The Standard

Draw two dimensional shapes and build or create models of three-dimensional shapes.

Maryland College and Career Ready Standards for Mathematics (2025) · WORK WITH TWO-DIMENSIONAL AND THREE-DIMENSIONAL SHAPES.

Teacher's field guide

What Students Need to Do: Students draw flat shapes, such as circles, triangles, squares, and rectangles. They use materials to make models of solid shapes, such as spheres, cubes, and cylinders.
What Mastery Looks Like: Students draw shapes with closed outlines and the right number of straight or curved sides. They make a solid model that can be picked up and name the shape they made.
Common Misconceptions: Students may leave gaps between lines or draw rounded corners on squares and triangles. They may think a drawn circle and a clay sphere are the same kind of shape.
How to Assess It: Give each student paper and clay. Ask them to draw a square and a circle, then make a cube and a sphere.

Lesson moves

Set out paper, clay, and craft sticks; children draw squares and circles, then build cubes with sticks and clay and roll clay spheres.
Show a paper circle and a clay ball; ask, “Which one can you pick up, and how would you draw each one?”
Put shape cards in a bag; children pick one, then draw it if it is flat or build it with clay if it is solid.
Show a soup can and a ball; children make clay models of both, then draw the flat shapes they see on the objects.
