A lesson based on the story, "Oliver's Fruit Salad," where students explore the concept of proportional reasoning through modeling, student sharing, and questioning. A great introductory lesson for this concept that is sure to engage...

A comprehensive lesson on algebraic thinking where students create and identify patterns using proportional reasoning. Research based, this lesson includes technology connections, items for discussion, and extension activities.

The object of this project is for students to learn how to find univariate and bivariate statistics for sets of data. Also, the students will be able to determine if two sets of data are linearly correlated and to what degree. The...

On this site, there are several math problems to explore and solve. Look through some solutions by famous mathematicians and expand your thinking about some interesting math concepts. Teachers of elementary grades may want to use this...

This lesson provides young scholars with opportunities to practice writing equivalent equations and expressions for finding perimeter and patterns on a calendar. It also gives extension and remediation ideas as well as related...

This question examines the algebraic equations for three different spheres. The intersections of each pair of spheres are then studied, both using the equations and thinking about the geometry of the spheres. Aligns with A-CED.A.2 and...
