How about one with two rows of 13? Why wouldn’t there be a box for 7 eggs? Children make posters of their designs, display them around the room, and have a “gallery walk” so everyone gets a chance to see the various containers. ) After the gallery walk Madeline convenes a math congress. Using a pocket hundred chart, the children record the numbers by placing colored transparent inserts in the chart to highlight the sizes of all the containers they have made. Although not all the even numbers are highlighted, enough are for children to begin to notice some patterns and to make predictions of other numbers that might be doubles.

I felt the focus was really on their development. It felt so genuine. Halfway through the session I realized I had been doing all of this Algebra: Structures or Structuring? 19 20 YOUNG MATHEMATICIANS AT WORK factor rainbow practice and no one was even using it! Instead they were using what they knew about multiplication. It made me wonder about so many of the cute things we do that we think will help kids but that are nothing but trivial activities. I like that my kids and all of us this morning were really finding so many new relationships among numbers.

He offers an interesting observation, although a bit tentatively. “I think maybe the numbers in the third column are the square roots of the numbers. Four is the square root of 2 and 9 is the square root of 3, and like that. ” In the past, Camille would have immediately focused on Anthony’s misuse of terminology. But correcting him at this moment may cause him to shut down, just as he’s beginning to shift the class discussion to multiplicative structuring. Therefore, she probes his thinking. ” “Well, 2 times 2 is 4, 3 times 3 is 9, 5 times 5 is 25.
