Skills:
K-2: subitizing, counting, colors, shapes, pattern
3-5: counting, shapes, even, odd, addition, subtraction, multiplication
Subitizing, being able to quickly recognize the total amount without having to count each member of the group, is an important part of developing number sense. In the primary grades, students who subitize are able to count on from the subitized number. In upper elementary, students can use subitizing to break a larger group into smaller equal groups to find the total. In this 10 x 10 grid, I used colored sticky dots to create opportunities for students to subitize.
