Georgia 1.GSR.4.2
The Standard
Compose two-dimensional shapes (rectangles, squares, triangles, half-circles, and quarter-circles) and three-dimensional figures (cubes, rectangular prisms, cones, and cylinders) to create a shape formed of two or more common shapes and compose new shapes from the composite shape.
Georgia's K-12 Mathematics Standards · Compose shapes, analyze the attributes of shapes, and relate their parts to the whole.

What This Standard Means
What Students Need to Do
- Students fit familiar flat pieces together to make a larger picture or outline. They also stack or join solid blocks, then reuse completed groups as parts of another design.
What Mastery Looks Like
- A student can select, turn, and join two or more pieces to match a target or create a design. The student names the parts and rearranges them into a different design.
Common Misconceptions
- Students may think turning a shape changes its name. They may leave gaps, overlap pieces, call every box a cube, or confuse flat shapes with solid figures.
How to Assess It
- Give each student shape cutouts and solid blocks. Ask them to build one flat design and one solid structure, name the parts, then rearrange each into something new.

Ways to Teach It
Give pairs pattern blocks and solid blocks to build a house, then rearrange the same pieces into a different object.
Show a composite picture and ask, “Which shapes do you see, and how could you move them to make something new?”
Play Shape Builder: draw a target card, choose matching pieces, build it without gaps, then name every part used.
Study a playground photo and recreate the slide, tunnel, and climbing structure with shape cutouts or solid blocks.
