Building with 3-D Shapes

MathematicsGeometryAges 6–7

Compose three-dimensional shapes (cubes, right rectangular prisms, right circular cones, right circular cylinders) and create composite shapes; build new shapes from component shapes

Teaching Table

Set out your lesson

Build a composite solid and name its parts.

Activity

Can discuss the supplied example in an accessible mode; adapt directions without supplying the target answer.

Policy

Check the learner can follow the model with support before moving on. Source prerequisite ordering is not learner mastery; return to prerequisite work when needed.

Use large stable blocks or closed light cardboard boxes; optional paper cone. Do not stack heavy objects, glass or cylinders that can roll off a table. Without solids, describe the supplied build recipes and record physical assembly pending. Open S first, G together, then T alone; put S and G away before T. Keys stay adult-only. No purchase or printing is required; an unavailable physical observation remains pending, not passed.

Materials are ready in each step. Use them on screen or print just the current step. Put teaching examples aside before the learner tries.

What this lesson covers and its limits

These are bounded opportunities, not learner attainment. Partial and blocked source requirements remain so.

partial: Compose three-dimensional shapes (cubes, right rectangular prisms, right circular cones, right circular cylinders) and create composite shapes; build new shapes from component shapes
Physical building and access to all named solids are conditional; text recipes are not a substitute for observed construction.
partial: Stack cubes and prisms to build towers or structures
Physical building and access to all named solids are conditional; text recipes are not a substitute for observed construction.
partial: Combine 3-D shapes to make a new solid (e.g. cone on top of cylinder)
Physical building and access to all named solids are conditional; text recipes are not a substitute for observed construction.
partial: Describe a composite 3-D shape in terms of its component shapes
Physical building and access to all named solids are conditional; text recipes are not a substitute for observed construction.
partial: Can {{name}} combine 3-D shapes — like stacking cubes and cylinders — to build a new composite solid?
