Virginia SOL 2.MG.4.a
The Standard
Trace faces of solid figures (cubes and rectangular prisms) to create the set of plane figures related to the solid figure.
Virginia Standards of Learning for Mathematics · The student will describe, name, compare, and contrast plane and solid figures (circles/spheres, squares/cubes, and rectangles/rectangular prisms).

What This Standard Means
What Students Need to Do
- Students place each face of a cube or rectangular prism on paper and trace around it. They name the resulting plane figures and match them to the solid.
What Mastery Looks Like
- Students can rotate a solid, trace each of its six faces, and name each tracing as a square or rectangle. They recognize that opposite faces match and that each tracing represents one flat face.
Common Misconceptions
- Students may trace only one face instead of rotating the solid to trace all six. They may call a square tracing a cube, or count the same face twice.
How to Assess It
- Give each student a cube or rectangular prism and paper. Ask, “Trace every face, name each plane figure, and circle the matching pairs.”

Ways to Teach It
Let students trace every face of a cube and rectangular prism on paper, marking each finished face with a removable sticker.
Ask students to write: “How are a cube and its square face different?” Then compare answers with a partner.
Play Face Match by having students pair mixed square and rectangle cards with the solid each card could come from.
Open empty food boxes and compare their flat faces with the rectangles students traced from assembled boxes.
