In a previous unit, students explored pattern blocks and filled in simple puzzles. In the previous section, students explored the attributes of and built individual flat shapes, such as rectangles and triangles. In this lesson, students explore putting together pattern blocks with sides touching to form larger shapes.

Count to answer “how many?” questions about as many as 20 things arranged in a line, a rectangular array, or a circle, or as many as 10 things in a scattered configuration; given a number from 1–20, count out that many objects.
Identify whether the number of objects in one group is greater than, less than, or equal to the number of objects in another group, e.g., by using matching and counting strategies.Include groups with up to ten objects
