In a previous section, students identified and named shapes in the environment, including shapes in different orientations. In this lesson, students use pattern blocks to figure out which shapes are the same. Students may analyze the attributes of the shapes or may rotate the pattern blocks to determine which shapes are the same.

Determine pattern blocks that are the same when presented in different orientations.
Explain (orally) how to determine if two pattern block shapes are the same.
In an upcoming lesson, students will put together pattern blocks to compose the same shape in more than one way. What do you notice in their work from today’s lesson that you might leverage in that future lesson?

Write numbers from 0 to 20. Represent a number of objects with a written numeral 0–20 (with 0 representing a count of no objects).
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.
