# Bricks In Fraction

## Explore equivalent fractions with bricks.

Objective:
Child will be able to visually represent equivalent fractions by overlapping different sizes of bricks.

Essential Question(s):
How do fractions with different denominators relate to each other?

Special Materials:
Paper and pencil for labeling

Bricks Required:
16×16 plates; 1×2, 2×2, 2×4, 2×8, 1×3, 1×4, 1×6 bricks

Project Structure

Engage/Explore

1. Have child lay out enough bricks to cover two rows of a 16×16 plate, using each type of brick (e.g., two 2×8 bricks and sixteen 1×2 bricks).
2. Ask child to place their plates on a sheet of paper and label each row: 1 whole, 2/2, 4/4, etc.
3. Ask child to find various equivalent fractions, such as 1/2 and 2/4.

Explain

1. Ask child to solve a few addition and subtraction problems with common denominators.
2. Ask child to use their boards to show the pieces for their fractions.
3. Have child develop an explanation and reasoning for the correct addition/subtraction of the problems, using the bricks as evidence.
