Curated OER
Is the System Fair?
Students investigate shapes and patterns. In this algebra lesson plan, students move from concrete to abstract understanding of shapes and concepts. They use variable to identify the unknown.
Curated OER
Polynomial Multiplication
Students review information about how to multiply polynomials and then work in pairs to complete a worksheet. They use graphing calculations to help them solve their math problems.
Curated OER
Writing Variable Expressions for Physical Models
Explore the concept of writing variable expressions by examining the similarities between expressions with numbers and expressions with variables. Emerging mathematicians determine rules for sequences and patterns before writing a rule...
Curated OER
Patterns and Functions
Students investigate properties of perimeter and area. In this middle school mathematics activity, students explore patterns in a problem solving context. Students model and solve problems using various representations for the data as...
Curated OER
Cartesian Coordinate System
Young scholars explore the Cartesian coordinate plane and plot points on the graph. They interpret coordinates for a point from the graph and give the ratio of rise over run for slope.
Curated OER
Figure This!
Second graders explore the concept of inequalities. They use the mathematical symbols =, <, > to show relationships among numbers. Students devise and use problem solving strategies to explore the situation.
Curated OER
Perimeters, Patterns, and Conjectures
Students discover patterns and write conjectures relating to perimeters and polygons. Working in cooperative learning groups, they use manipulatives and graphic organizers to solve problems then answer a series of questions in which they...
