Teachers encourage children to describe the pattern in a favorite story book.

Why is this important?

Children need practice and support to identify what repeats in a pattern. In the case of a growing pattern, it’s a quantitative change that repeats.

Identifying the rule of a pattern brings predictability and allows one to make generalizations. More

Mouse Collections

In this video, two teachers use Ellen Stoll Walsh's "Mouse Count" to illustrate the concept of "less and more."


People Sort

Children sort and re-sort each other, based on various attributes. This activity involves an open sort in which the categories can include a wide range of attributes that must be identified and described by the sorter.

    […] Another video shows the moment when the class discovers the “growing pattern” — a regular increase in quantity over time — in The Napping House by Audrey Wood. After reading the book, the class charts how many characters appear on each page: one additional character per page. “It looks like stairs!” says one boy. Another chimes in, “It’s adding up. First there’s one, then there’s two, then there’s three. We’re adding one more to each [page].” The video shows how the teacher structures the activity and the conversation to lead to math discoveries. A description on the site explains that recognizing patterns like this is one of the foundations for algebraic thinking. Watch the video […]
