Study Guide — 6.G.A.4
Represent three-dimensional figures using nets made up of rectangles…
Compare flat (2D) and solid (3D) shapes and describe their features.
What this standard means
- Represent three-dimensional figures using nets made up of rectangles and triangles, and use the nets to find the surface area of these figures. Apply these techniques in the context of solving real-world and mathematical problems.
- Apply represent three-dimensional figures using nets made up of rectangles… with models and explanation
- Identifies 2D vs 3D shapes

How to use the 20 practice sets
| Sets | When to use | | --- | --- | | 1–5 | Intro — explore together, short written items | | 6–10 | Core skills — diagrams and written practice | | 11–15 | Mixed review — explain thinking | | 16–20 | Stretch — word problems and mastery tasks |
Pacing: 10–15 minutes per session.
How to practice
1. Match real-world objects to shape names 2. Draw flat faces of solids 3. Build solids with clay or blocks
_See printable PDF for diagram._
Common mistakes
- Calling a flat drawing a solid
- Missing faces on 3D models
Review and practice tests
1. Start Review 1/10 when sets 1–3 feel comfortable. 2. Move up one review level with little help. 3. Use Practice Test 4/10–6/10 for mid-standard checks. 4. Practice Test 10/10 is the mastery bar for 6.G.A.4.
