# Building Blocks

Wooden cubes can be used for a variety of building activities that develop spatial skills and mathematical reasoning. In this activity, students make a 3-dimensional shape using a given number of cubes.

Curriculum Topics: 3-dimensional Shapes, Spatial Skills, Mathematical Reasoning

6.G.4. 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.||Common Core Mathematics||Grade 6||Geometry||Solve Real-World And Mathematical Problems Involving Area, Surface Area, And Volume

3.6 Visualize, describe, and make models of geometric solids in terms of the number of faces, edges, and vertices; interpret 2-D representations of 3-D objects; and draw patterns for a solid, that when cut and folded, will make a model of the solid.||CA Mathematics||Grade 4||03. Measurement and Geometry||3.0 Students demonstrate an understanding of plane and solid geometric objects and use this knowledge to show relationships and solve problems.
