How do you get a theorem named after you? Euler knows what it takes! The third lesson of five asks pupils to use an interactive activity to compare the faces, vertices, and edges of seven different three-dimensional solids. They use...

Learners represent and solve problems using geometric models and apply geometric properties and relationships. They also practice constructing and measuring angles. By constructing, drawing, visualizing, and comparing geometric figures...

Students compare contemporary cultural differences with historical differences based on population percentage. In this cross-curriculum Gold Rush/math lesson, students analyze aspects of California's Gold Rush population and diversity...

Students create a quilt square for a class quilt using at least three, two-dimensional geometric figures. They research and write a brief description of at least two different quilt patterns that they find. Pupils discuss that quilts are...

Circles are the foundation of many geometric concepts and extensions - a point that is thoroughly driven home in this extensive unit. Fundamental properties of circles are investigated (including sector area, angle measure, and...

Students research the history of measurement in this lesson. They compare todays units of measurement to historical units of measurement. For example, they weigh themselves on a bathroom scale and figure out how many of them it would...

Make history come to life by using the Frontier House series to engage students in the past. Your class will "prepare" for a trip to 1833 Montana. They will learn about homesteading, frontier life, inflation, and cost of living. Using...

Tenth graders investigate the history of geometry and its different shapes. In this geometry lesson, 10th graders practice seeing three dimensional shapes and explain why there are only five polyhedra. They relate all the new materials...
