Pre-K – Grade 2

Numbers Many Ways

Students work with subtraction at the intuitive level as they explore number families and ways to decompose numbers to 10. They will also identify members of fact families, a set of three (or two) numbers that can be related by addition and subtraction.


Grades 3–5

High Temperature

In this lesson, students complete a chart by adding or subtracting from a given value, use graphs to compare two categories of information, and identify number patterns.


Grades 6–8

Polygon Capture

In this lesson, students classify polygons according to more than one property at a time. In the context of a game, students move from a simple description of shapes to an analysis of how properties are related. This lesson was adapted from an article that appeared in the October 1998 issue of Mathematics Teaching in the Middle School.


Grades 9–12

Building Connections

This lesson focuses on having students make connections among different classes of polynomial functions by exploring the graphs of the functions. The questions in the activity sheets allow students to make connections between the x-intercepts of the graph of a polynomial and the polynomial's factors. This activity is designed for students who already have a strong understanding of linear functions, some knowledge of quadratic functions, and what is meant by a polynomial function.
