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...
Curated OER
Wing Shapes and Areas
Students, after reading the explanation given below, use FoilSim to determine the weight of the aircraft that can be lifted by a pair of wings of each type. They also design a unique platform of a wing to lift a plane weighing 11500 pounds.
Curated OER
How Many Bears in the Forest?
Third graders model the tag and recapture of bears and use proportions to estimate the population of the bears in their forest. This is a statistical sampling method used by scientists and naturalists to determine population numbers.

Better Lesson: Inequalities
If a < b, what do we know about a and b? If b < c < d, how could we show that on a number line? Students continue creating inequalities and graphs to represent situations.

Alex: Graphing Is Great!
Students will explore graphing individually and in groups. They will also use an interactive activity to discuss slope and intercepts. To assess the lesson, students will use the floor tiles in the classroom as a large sheet of graph...

Alex: Focusing on Graphs
In this lesson, students will solve systems of linear equations by graphing. Systems of linear equations are two or more linear equations together.

Alex: Human Slope
Students will participate in this discovery activity intended for them to uncover the role each variable plays in the graph of a line in the form y = mx + b. Students will actually demonstrate lines in slope intercept form on a life size...

Alex: A Piece of Pi
This lesson uses graphing to help young scholars understand that pi is a constant and is the slope of the line graphed on a circumference vs. diameter graph.This lesson plan was created as a result of the Girls Engaged in Math and...

Alex: Finding the Slope of a Line
This instructional activity will use a slide presentation to facilitate teaching young scholars how to find the slope of a line when given the graph of the line or two points. Students will interact with the presentation in two ways:...

Alex: Systems of Equations: What Method Do You Prefer?
The purpose of this lesson is to help students apply math concepts of solving systems of equations to real life situations. The students will use the three methods of graphing, substitution, and elimination to solve the system of...
