# Solid Shape Sort

Give your students a head start on 3D shapes with this lesson that has them use their observational skills to identify what differentiates the shapes.

Students will be able to identify different 3D solids given their characteristics.

(10 minutes)
• Pass out a set of 3D shapes to each group as well as the 3D Shapes worksheets to each student.
• Define a shape's faces as its flat sides, a shape's edges as the line where two faces meet, and a shape's vertices as the point where two edges meet.
• Having students stay in their groups, have them examine the 3D shapes together to identify the number of faces, edges, and vertices each has.
• Have students then look at the 3D Shapes worksheet to determine the names of the solids shown.
(10 minutes)
• Ask students to think about the characteristics of each shape and how it determines how the shape could move. For example, can the shape roll? Can it be stacked?
• Have students volunteer their thoughts and test them with the set of 3D shapes.
• Review the number of sides, edges, and vertices each shape has once more.
(15 minutes)
• With a partner, invite children to use the characteristics of the shapes to play I Spy.
• In this game, students should take turns identifying solids by listening to clues such as, “I spy with my little eye something that can stack.”
• Children get three guesses before another attribute is added, such as “I spy with my little eye something that can stack and has 6 faces.”
• The student who guesses will have to explain how he or she knows. They will then give clues for the next object.
(10 minutes)
• Students will work independently to complete the 3D Shapes worksheet.
• Enrichment: Advanced students may write a more detailed entry in their math journals.
• Support: Allow struggling students to continue to use the 3D shapes as they complete the lesson.
(10 minutes)
• Ask students to hand in their worksheets when finished.
• Have students write 4 sentences in their math journals about the characteristics of 3D shapes.
(5 minutes)
• Bring students together to review the characteristics of solids and how we use those characteristics to sort 3D figures.
