Curated OER
Perimeters, Patterns, and Conjectures
Learners 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...

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: 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: Finding the Slope of a Line
This lesson plan will use a slide presentation to facilitate teaching students 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: first, by taking...
