Your teacher will demonstrate how to use the Block Builder interactive.

INTERACTIVE: Block Builder

Build an arrangement of cubes when given the front view and side view of the arrangement.

The figures show the front and right side views of a construction made of cubes.

Use the Block Builder interactive, actual blocks, or paper and pencil to complete the following tasks.

- What is the least number of cubes that you could use to make a cube structure that has a front view and right side view as shown above?
- Sketch a diagram by hand, use blocks, or use the Block Builder interactive.

You can start by building the bottom layer first. Look at the structure from the front: how many cubes do you need based on this view?

Look at the structure from the side: how many cubes do you need based on this view?

If you have difficulty getting started, try this describing the task in your own words to your partner.

- What do you know?
- What are you trying to find?
- What tools can you use to help you?
- What strategy can you try?

If you have a solution, try this:

- Explain your strategy for solving the problem.
- Why did you approach the problem that way?

INTERACTIVE: Block Builder

Prepare a presentation about your solution to the cube problem. What steps did you use to help you solve this problem? Use illustrations and explain your approach to the class.

Now, think of the problem you just solved, and create a new problem that's similar. Then trade with a partner and solve each other's problem.

Remember to include a front and side view of your building. If the left and right side of your building look different, you must include both views.

Take notes about other classmates' approaches to the cube problem. Think about the problem-solving process you used to find the number of cubes needed to make this structure.
