# Build a Structure from 3 Different Views

## Curriculum Goal

#### Primary: Geometry and Spatial Sense

• Compare two-dimensional shapes and three-dimensional figures and sort them by their geometric properties.
• Compose and decompose two-dimensional shapes and three-dimensional figures.

#### Junior: Geometry and Spatial Sense

• Identify and classify two-dimensional shapes by side and angle properties, and compare and sort three-dimensional figures.
• Sketch three-dimensional figures, and construct three-dimensional figures from drawings.

## Context

• Children will do this activity on the carpet initially and then individually either at their desks or on the carpet.​
• Children should have experience playing with interlocking cubes.​

## Lesson

• Facilitate a discussion to prompt students to think about how to transform a 2-D drawing into a 3-D structure.
• Provide students with interlocking cubes (about 20) and the Three Views Picture.
Ask students to imagine if they were a bird flying over and round a building. How would they describe the structure and its different views?
• Then, ask students to look at Three Views Picture
• Ask students to make a building that has the same top view, front view, and side view as Three Views Picture
• Encourage students to compare their structures with each other to verify that their structures match the examples in Three Views Picture

## Look Fors

• What directional or positional language does the child use? (e.g. over, under, left, right)​
• Do they use the proper names of 2-D and 3-D shapes?​
• Can they articulate how they interpreted the 2-D pictures and applied that to the 3-D structures?​

A possible extension, students transform a 3D figure into a 2D drawing from 3 different viewpoints.

In this lesson, students will use multilink cubes to recreate an image of a structure.
