Unit 5, Lesson 7

Name and count shapes as parts of a whole, recognizing relative sizes of the parts.

EngageNY 60 min(s)

In this lesson, students explore composite shapes that have been made throughout the module and sort them into two categories of shapes: those made from equal parts and those made from non-equal parts. Then they count the number of equal parts that form one whole.

Standard 1.G.A.3

Partition circles and rectangles into two and four equal shares, describe the shares using the words "halves", "fourths", and "quarters", and use the phrases "half of", "fourth of", and "quarter of". Describe the whole as two of, or four of the shares. Understand for these examples that decomposing into more equal shares creates smaller shares.

1st Grade

1.G.A.2

Compose two-dimensional shapes (rectangles, squares, trapezoids, triangles, half-circles, and quarter-circles) or three-dimensional shapes (cubes, right rectangular prisms, right circular cones, and right circular cylinders) to create a composite shape, and compose new shapes from the composite shape.

2.G.A.3

Partition circles and rectangles into two, three, or four equal shares, describe the shares using the words halves, thirds, half of, a third of, etc., and describe the whole as two halves, three thirds, four fourths. Recognize that equal shares of identical wholes need not have the same shape.
