What This Standard Means
What Students Need to Do
- Students recognize and name cubes, spheres, cylinders, and cones when they see objects around them. They match everyday items to the solid they resemble.
What Mastery Looks Like
- A student correctly matches common objects to cubes, spheres, cylinders, and cones. The student uses the solid names rather than flat shape names.
Common Misconceptions
- Students may call a sphere a circle or a cube a square because they focus on one flat face. They may confuse cones and cylinders or think object size changes the solid’s name.
How to Assess It
- Show a ball, soup can, party hat, and number cube. Ask students to name the solid each object resembles.

Ways to Teach It
Set out a ball, soup can, party hat, and number cube, then have students sort and label them with solid-name cards.
Ask, “How is a soup can like a cylinder, and how is it different from a sphere?” Record students’ observations.
Play Mystery Bag: students feel one hidden solid, name it, then pull it out to check.
Take a classroom solid hunt and photograph one object resembling each solid for a class chart.
