Georgia 1.GSR.4

1.GSR.4 is a Georgia mathematics standard. These are the expectations under it.

• 1.GSR.4.1

  Identify common two-dimensional shapes and three-dimensional figures, sort and classify them by their attributes and build and draw shapes that possess defining...

• 1.GSR.4.2

  Compose two-dimensional shapes (rectangles, squares, triangles, half-circles, and quarter-circles) and three-dimensional figures (cubes, rectangular prisms, con...

• 1.GSR.4.3

  Partition circles and rectangles into two and four equal shares.

01

What Students Need to Do

Students join two or more shapes to make a new shape. They describe shapes using sides, corners, faces, and other visible features. They explain how smaller shapes form a whole figure.

02

What Mastery Looks Like

A student can combine given shapes to make a target shape or an original figure. The student names the parts and describes attributes of both the parts and the whole.

03

Common Misconceptions

Students may think a rotated square is no longer a square. They may name shapes by color or size instead of sides, corners, and faces. They may see only the finished figure and miss the smaller shapes used to make it.

04

How to Assess It

Give each student two paper triangles, one square, and one rectangle. Ask, “Make a new shape with at least two pieces, name each part, and describe one attribute of the whole.”

1. 01

   Build a larger shape with pattern blocks, trace it, and label which smaller shapes make each part.

2. 02

   Show two composite figures and ask, “How are their parts and attributes alike and different?”

3. 03

   Play Shape Builder: draw a target card, then combine two or more cutout shapes to match it.

4. 04

   Study a window, sign, or floor tile and sketch the smaller shapes that form the whole design.

• 2.GSR.7

• K.GSR.8

  Identify, describe, and compare basic shapes encountered in the environment, and form two-dimensional shapes and three-dimensional figures.
