Using Algebra Tiles to Explore Distributive Property
Math is fun with algebra tiles! Young mathematicians explore eight expressions involving the distributive property and use algebra tiles to expand simple expressions. The resource is perfect for both guided and independent practice.
Illustrative Mathematics
Red and Blue Tiles
Here, second graders are tasked to find the patterns that have an even number of tiles. They are asked to think about why these patterns are even or odd and explain how they know.

Exploring Tessellations
Tessellations are patterns of repeating shapes that don't overlap and don't have any gaps. Middle schoolers take this simple definition and engage in a instructional activity that combines visual art and mathematics. They cut out index...
Curated OER
Perimeter All Around
Students explore perimeter and area of regular and irregular polygons. They experiment with color squares and create different arrangements using the same number squares. Then they compare the area and perimeter measurements of each.
Curated OER
Prime and Composite Numbers
Eighth graders explore prime and composite numbers. Given division problems, they use color tiles to model solutions to division problems. Through activities and observation, 8th graders discover the meaning of prime and composite...
