Building back up confidence in math throughout Summer

I find it somehow arduous to follow what my daughter, Rosie, 8, learns in math on a daily basis during the school year. But in Summer, I usually am committed to catch up with what I have missed, especially as we usually have quite low key Summer at home.

  • Two years ago, I decided to use the Common Core Math Standards (here) to come up with weekly activities to review with Rosie what she had learned in K. We had a fun Summer of learning, but it was quite time-consuming to plan it.
  • Last Summer, I tried to take the same path, but could not keep up with the M.Ed. Summer courses I had to take in paralell. Rosie was a happy child in 1st grade, seemed confident in her math skills, so we ended up doing math mostly informally throughout Summer.
  • This year, I decided to try something new with my now rising 3rd grader. I had to, as Rosie came home one day, the last week of school, claiming “I know I am not smart, I don’t even know my multiplication facts *”. Sigh. I have 10+ weeks to build back up her confidence.

So here is what we have been doing:

  1. Every day, Rosie explores a word problem “in any way that makes sense to her”, as recommended in Carpenter et al, 2014. We have been using the pool of word problems discussed in one of our previous posts (here).Summer Bridge
  2. She also works on a daily worksheet from Summer Bridge. I rarely give worksheets to my kids, but I was curious to connect our Summer learning with some of the math activities that Rosie does at School, and see if she needed any kind of reassurance on that front.  There are dozens of books to review Standards throughout Summer, I picked one that does encourage children to explain their reasoning in math. So far, I have liked it.
  3. Once a week, we go to the library to pick up books related to math that we read informally throughout the week (click here for more details) .

And so far, it has been working quite well ! You may want to give it a try, it is not too late !

  • It is short. Within 15-20 min, Rosie is usually done with her “formal” learning time and has the rest of the day to keep learning… through free play!
  • The exploration of word problems has been quite nurturing. She started Summer with trying to remember the procedure she was taught at school, doubting of herself when she could not, to reaching out a new level of confidence, making sense of the problems on her own. As always, I mostly listen, asking questions from time to time to make sure I follow her reasoning.
  • Observing Rosie filling up worksheets has been quite instructive as well. Most of the Summer Bridge activities encourage math thinking. Still, a few do not.
    • Practicing additionI could see Rosie’s face change the first time she had to solve a dozen addition or subtraction problems in a row (see picture on the right), her eyes begging me to let her skip the few pages providing such a repetitive task. “Let’s just try to make it a little bit more exciting, Rosie. If you had to pick 5, which ones would you pick?”. Now she does not solve them like a machine, she thinks first. “I will do 688+102 because adding 102 is like adding 100 and then 2 more, so I already know it is 790!”.  I understand that practicing a skill develops fluency, but fluency  should not Subtractioncome with… a lack of thinking. At the CGI conference I attended last month, we were shown a video of  a high schooler, enrolled in advanced math courses,  solving 4001 – 3998 … with a standard algorithm (see representation on the left). He was so used to using the procedure that he did not notice that the subtraction could be performed mentally (believe me, it happens to the best of us… See one of our previous posts “When I got swallowed into the symbolic level“). En garde !
    • Word ProblemI also noticed how being invited to solve a problem in a little square puts Rosie back in some kind of school tracks, away from freely showing her way of thinking. She did mention though that I should feel lucky, she could have just written 34 or 32, without any units or equations.
  • Exploring math book has also boosted our math talks, as discussed here.

We shall see what the rest of Summer may bring, but so far, combining word problems, worksheets, and math books has provided us with a good balance of learning. Indeed, I even found a little fairy waiting for me on the kitchen table last week. A math fairy. She seems rather happy and confident, don’t you think? I just hope she does not fly away at the end of Summer. MathFairy


It is by the end of 3rd grade that students are supposed to know their multiplication facts, so obviously, Rosie, you still have plenty of time.

CCSS.MATH.CONTENT.3.OA.C.7
Fluently multiply and divide within 100, using strategies such as the relationship between multiplication and division (e.g., knowing that 8 × 5 = 40, one knows 40 ÷ 5 = 8) or properties of operations. By the end of Grade 3, know from memory all products of two one-digit numbers.

“Exploring the math shelf #1” – How to pick math books for a meaningful discussion

I often write about how much I enjoy listening to a child making sense of a math problem. But something I find quite fulfilling as well is reading books with my children (any child, actually). No need to say that I am quite excited about our new journey, “Exploring the math shelf”, that takes us weekly to our public library to explore their selection of math books.

Before I start discussing books we have checked out, I thought that sharing our book selection process could be helpful as well. It has indeed been working quite well for us, considering the math discussions that have popped up at our house in the past few weeks.

At some point, I expect, well, I hope, my kids will be naturally attracted to the math section, and pick math books on their own. For now though, I think they count on me to do so :-).

  1. FullSizeRender-1I usually do not have any specific math books in mind when I arrive at the library. I like to browse the shelf.
  2. Often, I take several books around a math concept my kids have been talking about, such as place value, multiplication or fractions.
  3. I try to mix stories (e.g. “Earth Day – Hooray”, by S. J. Murphy and R Andriani, a story illustrating place value) with books specifically detailing a math concept  (e.g. Place Value, by D. A. Adler). That way, we can have an informal math talk while reading a story, and have access to other more detailed sources if my children raise a particular math question.

Once home, we read books when we feel like it. Sometimes at night, sometimes during the day. Unlike with the story books, we rarely read our “math” books from beginning to the end. Rather, we discuss a page or two at a time, such as page 8-11 in Place Value, where the number system is compared to the alphabet. But we go back to the books several times during the week.

One more thing: I do read the math books with my kids. Indeed, you would be surprised by the imprecision, and even inaccuracies you may find in math books. I checked out recently a book about multiplication, and was quite excited to see that the equations included the units. I always encourage my child Rosie, 8,  to do the same when she solves problems (e.g. 2 cats + 3 cats = 5 cats). Indeed, there is no need to wait for a Chemistry course to begin such a helpful habit. Alas, in the book, to illustrate 2 baskets containing each 7 tomatoes , the equation was:

7 tomatoes X 2 baskets = 14 tomatoes.

Somehow, magically, the “basket” unit disappeared (to produce more tomatoes???). Now if the equation had been written as follow, I would have highly recommended the book:

7 tomatoes/basket  X  2 baskets = 14 tomatoes.

I have to say, though, that once you are aware of possible misconceptions, and discuss such eventualities with your child, it opens a new door to more meaningful math. Rosie is now on a new quest:  “See, Mom?  They say that you have to use the zero mark when you use a ruler. But you don’t have to ! It is easier, but you don’t have to !”. Never too early to become a critical reader.

Have fun reading !


Exploring the e-community of math education

Sometimes, I feel like I am rowing upstream, supporting mathematical thinking at home while so many school decisions are still based on test results, leading numerous parents and educators to teach quick “tricks” rather than providing daily opportunities to make deep sense of math. Meeting people sharing my beliefs in math elementary education at a conference last month was extremely refreshing. Fortunately, such revitalizing feeling did not end with the conference. I noticed that, indeed, plenty of ideas and thoughts related to mathematical thinking are daily shared through the web.

Twitter, for instance, seems to be a puissant platform. I knew about it, of course, but I had never taken the time to explore it before the conference. Since it was widely used by the organizers as well as many of the participants, I decided to give it a try. I do not expect to tweet a lot. Indeed, the cogitative person I am is truly out of her comfort zone on Twitter: I have seen me drafting a Tweet, thinking about it, amending it, redrafting it, and ending up … deleting it, as the “time” to tweet my thought had past. But there is another powerful angle of Twitter I look forward to digging into: its use as a database. Whether you follow people from the field of math elementary education or search hashtags related to math education, Twitter seems to open the door to endless resources.

Also, it is time for me to explore further the blogosphere. The conference made me discover three blogs that I will follow with deep interest. I sure will keep you posted with other findings.

Whether you read my blog as a parent and/or an educator, I sure hope this post will help you connect with the e-math-community. The more, the merrier !


It sure is a journey !

When I decided, a couple of years ago, to start this blog, I saw it as a journey, my journey as a parent helping my children with math at home, willing to share all the good stuff I would learn as a M.Ed. student in math elementary education to, hopefully, inspire other parents.

It has, indeed, been an instructive journey. And attending recently a conference dedicated to Cognitively Guided Instruction (CGI) makes me feel like embracing the journey even more. In the past two years, I have enjoyed listening to my children solving problems “a way that makes sense to them” (Carpenter et al, 2014) and meeting the CGI community deeply confirmed my beliefs in such approach. CGI can be complex to describe, but in the context of this blog,  I would define it as a math instruction focused on how children think in math i.e. children’s mathematical thinking: children are invited to explore problems prior to receiving any formal instruction, prior to being introduced to any symbols or procedures. While children make sense of a problem, adults listen. In a CGI classroom, as children share their work, teachers embrace opportunities to build up their math instruction. At home, of course, one may not expect a nurturing classroom discussion. Still, I believe the exploration as such, without time pressure or peer pressure, the “out-loud” thinking is quite valuable. I have opened the door of my house to CGI, and I have enjoyed sharing my experience as a parent on this blog.

I often wonder, though, how I can reach out to more parents. Because it was, of course, my main goal in blogging: helping other parents. I use pen names, which makes it trickier to use social media as a megaphone, and I am more of a “behind-the-curtain” kind of person. So I guess the key will be to get back to more regularity  in my posts. Luckily, I came back from the conference with plethora of new activities to do with my kids, new blogs and resources to explore. So from now on, you can expect to find, once a week, at least one of these posts :

  • “Solve and Share”:  I will continue to post word problems to explore across elementary grades but I will include additional children strategies from the literature to complete the experience I have with my own children. Hopefully, these posts will inspire you to welcome CGI at home.
  • “How many?”: I am super excited about sharing this activity as I have done it a couple of times with my kids, and they loved it. I will dig further to let you know the genesis of it and explain it in further details when I write our first post but basically, you show the kiddos a picture, and ask them “how many?”. And they can count … whatever they want. They may start with counting items one by one, but the picture can open up to counting by groups, finding arrays, discussing fractions, etc. Here is a picture to help you start thinking about it.

HowMany#3

  • “Exploring the math shelf”: I naturally add math questions to any book I read to my kids, but I discovered an entire shelf dedicated to math books at our library (I know, it is about time). I started reviewing them, I have to say that some are much better than others. No wonder why kids get easily confused with math ! So each time we go to the library, I will bring a few math books and share my thoughts with you.

MoreSummerBooks

Of course, I will continue to post about any relevant matter for parents I read  as a doctoral student. Please, do not hesitate to share your thoughts as well, and raise any questions you may have. Time to fully connect with the math e-community !

Exploring word problems throughout Summer

Summer break is here, and we are back to exploring word problems regularly.

Here is a good source of word problems if you want to do the same:

South Dakota Booklet

As always with our math journeys (e.g. Time 4 Fractions or WedWordPro), I simply invite my child Rosie, 8, to solve a problem in a meaningful way to her (Cognitively Guided Instruction, Carpenter et al, 2014), and share her thinking out loud. Drawing a visual representation on paper to make sense of the problem, using manipulatives (e.g. buttons, Legos®, Base Ten block, flashcards to fold and cut, etc), writing an equation and solving the problem using a strategy of her choice, it is up to her, I just listen 🙂

Enjoy !

An activity from Education.com

I was contacted recently by Education.com requesting that I post one of their hand-on activities. Since a component of blogging I truly value is supporting others on a similar journey, I decided to agree !

If you like the activity, you may want to check out their website, they have many more www.education.com/resources/math/


Activity : Tip the Scales for Estimation
Fifth Grade Math Activities: Tip the Scales for EstimationOkay, checking addition problems can be boring. Solving a math problem twice can be tedious. But finding the total weight of a group of family members can be hilarious, especially if your child is calculating and estimating the weight of a diverse group of subjects, like an 8 lb. cat, a 22 lb. toddler, and a 180 lb. grandpa!
  • Bathroom scale
  • Paper
  • Pencil
  • Family members

What You Do:

  1. Have your child record the weight of several willing family members. Have a scale available, if needed. These family members can include parents, siblings, grandparents, aunt and uncles, cousins and pets.
  2. Ask your child to add up the weights of all the participants to find the total number of pounds the group weighs.
  3. Using estimation, have your child check to see if his calculated results are reasonable. Suggest to your child that he first estimate the weight of each individual to the nearest ten pounds or five pounds. This is especially important if the individual is a pet. Sometimes it’s hard for kids to estimate the weight of adults. If your child’s estimation is not reasonable, suggest a more reasonable number. Then ask him to add all of the estimated numbers together.
  4. Have your child compare his estimation to his calculation. Discuss the use of estimation to verify, or check, calculations. Give examples of how this tool can be helpful in real world situations. If you’d like to extend the activity, start thinking about multiplication and division. How many cats would weigh the same a grandpa? How many baby sisters would weigh the same as Dad? Have fun calculating the numbers, and with your family, too!

Misconceptions in math

If you have visited this blog for a while, you may have noticed my continuous quest in helping children deepen their understanding in math. I share here what I do as a parent with my own children, hoping that it could help other parents as well. At home, I use games, math discussions,  explorations of word problems, etc. But I also try to identifying any misconceptions they may have in their learning.

Example.

My son Tom, 5, has learned how to count by Fives and Tens, while playing hide-and-seek with older kids.

– “Ten, Twenty, Thirty, Forty, Fifty, Sixty, Seventy, Eighty, Ninety, One hundred ! Ready or not, here I come !”.

I was quite surprised, initially, to hear him count by Ones, Fives, and Tens, as it is not a concept often mastered at a young age. So one day, as he was playing with his cars, I asked him if he could count them.

– “Sure !”, he said, pointing one car at a time, “One, two, three, four, five, six, seven, eight, nine, ten !”.

– “Could you count them by five?”, I asked

– “Sure !”, and pointing one car at a time as he did while counting by Ones, he counted : “Five, Ten, Fifteen, Twenty, twenty-five, thirty, thirty-five, forty, forty-five, fifty !”.

– “Could you count them by Tens ?”, I asked

– “Sure ! Ten, Twenty, Thirty, Forty, Fifty, Sixty, Seventy, Eighty, Ninety, One hundred !”, pointing again one car at a time.

He could root count by Ones, by Fives, by Tens up to a hundred and more. But he did not understand that counting by Fives means counting by groups of five, counting by Tens means counting by groups of tens. For him, it was just three independent ways of counting. You have ten cars when you count by Ones, fifty when you count by Fives, a hundred when you count by Tens. But since you “usually count by Ones”, you have ten cars. Seems logical in Tom’s world.

With Tom, 5, a discussion is usually the best way to assess his understanding, with a “tell me about what you are doing”, or “what does it mean to …”. With Rosie, 8, I like to use pretend-playing : she is the teacher, I am the child. I do not do it often during the school year, but Summer break is a fun time to do so. And since Summer break starts tomorrow… you should hear more about it pretty soon.

Stay tuned !
