Challenge The Least Number of Blocks
jOb ective Use the least number of cubes to make a figure.
1. Textbook Instructions Challenge The Least Number of Blocks
Students have learned how to find patterns, 1 . Use the least number of Blocks A and B to make the shapes on
the number of cubes, including hidden cubes,
and how to build upon existing figure. the cards. In this challenge, students will use two kinds of block pieces to make different
In this exercise, they will use geo cubes to
make various figures using the least number figures. Have them assemble each figure using the least number of pieces.
of blocks.
Let’s Play
What you need:
1. Use geo cubes to make Blocks A and B. Geo Cubes
2. Use Blocks A and B to make the shapes on the

using the same number of cubes. They will
use combinations of Blocks A and B to make
other figures.
How many ways are there to assemble
Blocks A and B to achieve the
configuration at the bottom of the page? Block A Block B
Two ways. Block A: 2 pieces First, have students assemble the two
Block B: 3 pieces pieces using their geo cubes.
Which way uses the least amount of Block A: 3 pieces
So, the number of They should use multiple number of Block B: 0 pieces
blocks is 5. pieces for each problem.
So, the number of
pieces? The second way. blocks is 3.

2. Build Understanding
Using the Least Number of Pieces
There are two ways to solve this problem.
Method 1: Make two pieces of L-shaped blocks (Block A), each using three cubes. Place the pieces side by
side. Put one Block B on each piece of Block A, to form a square. Then put another Block B on
top of one Block A.
2 Block As 3 Block Bs 5 pieces
Method 2: Set two pieces of Block A side by side. Put another Block A piece on top of the side that is only
one block deep.
3 Block As 0 Block Bs 3 pieces
