# Math Without Worksheets

One of the best things about teaching math from a Constructivist perspective is the emphasis on metacognition, or “thinking about thinking”. In a good Constructivist classroom the teacher should know, and be constantly assessing, the thinking strategies her students are using to solve problems. One of the ways I accomplished this when I was a teacher was through small group white-board activities.  I would group three to five students according to ability level, and let them create and solve word problems on the white-board for me, while I reordered their thoughts and strategies.

From a Constructivist perspective, listening to how children solve problems is where the true art in teaching comes. You need to know when to ask probing questions, when to lead them on to more efficient ideas, and when to pick apart what they are saying. The idea behind Constructivism is not to let kids wildly flounder, but to gently encourage them towards efficiency and accuracy.

My son Bruce(6.5) attends a school where the district uses Houghton Mifflin Math Expressions, which I like, but would not describe as a Constructivist program. Although there are occasionally times built into the curriculum where Bruce is asked to write out his own math problem as part of his homework, or explain his thinking in words and pictures, there doesn’t seem to be the same heavy focus on metacognition that there was in my own classroom.

Last night after dinner, I decided to do an experiment. How would Bruce handle a third grade Constructivist classroom? How would he do if he was in one of my white-board groups, from long ago? It turns out, not so well, at least not without more practice. And let me tell you, after realizing this type of activity was a struggle for him, we will be working on it at least once a week from now on!

Here is our first example. I asked Bruce to tell me a subtraction story problem about the number 263. That was the first bit of difficulty as you can see!  Then I asked him to solve the problem with numbers on the left side of the paper, and to keep his work neat, and organized within the box. Second bit of difficulty! I also wanted him to write down his final answer and circle it, but I forgot to articulate this very well, so that was “my bad”. Lastly, I asked Bruce to explain his thinking to me while I reordered his strategies. This is when he really started to flounder.

Okay, let’s try again! If you look at this next example, you can see a slight improvement. The story follows the word problem, his number work stays to the left, and he circled his final answer…but his explanation? On paper it looks okay, but I really had to tease this out of him. It did not come clearly or easily even with me doing the writing for him!

In a Constructivist classroom, by the end of fourth grade I would expect a learner to be able to see a number problem, write a story to go with it, and then write out their proof of how to solve it both in numbers and words. I would expect to see clear thinking, organized work, and neatness. None of that, is as easy as it might sound.

Sometimes, these types of Constructivist activities make certain parents turn vinaceous with annoyance and anger that comes from misunderstanding. I would never expect a child to have to write about every problem they solved. Nor do I think it is fair to hold children back mathematically because they might struggle with reading, writing or language. But doing proof work like this once a week in a small group setting is really helpful for everyone. Teachers get insight into how children are thinking, kids learn from the strategies of each other, and mathematical communication skills get practiced.

As an at-home activity, this has the added bonus of being completely free. I am going to continue working on this type of proof work with Bruce in an Afterschooling setting. I like Houghton Mifflin and I am extremely happy with Bruce’s teachers, but I want him to be successful at work like this too.

Singapore starts those kinds of problems (on a simpler level) in the 1A book. The student isn’t expected to write much at that level for obvious reasons but it’s definitely a similar type of exercise. My DS did some the other day where the book showed a picture that had X items in one group and Y items in the other. He had to come up with 2 addition stories and 2 subtraction stories for each picture and write the corresponding equations. It took a bit of work because he kept wanting to write equations that didn’t match the picture (like 12 = 10 + 2 for a picture that had a group of 12 and a group of 4). But eventually he caught on.

Yet another example of Constructivism in Singapore!
