Ordered Pairs
Scholars learn to plot points on the coordinate plane. The lesson introduces the idea that the first coordinate of a coordinate pair represents the horizontal distance and the second coordinate represents the vertical distance.

Points in the Coordinate Plane
Map your way to success in understanding coordinate points. Individuals drag town landmarks to their appropriate locations on a coordinate plane representing a map. They answer a set of challenge questions to see if their answers are...

A Watery World
With about 70% of the earth's surface covered in oceans, it's fair to say that we live in a very wet world. Young scientists gain a better appreciation of this fact as they use maps to identify the world's ocean basins in the first...

Square
Don't be a square! Young mathematicians determine the slope and length of a line segment. They then prove whether four given coordinate points form a square.

Circles: A Geometric Perspective
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...

Similar Triangles
Proving triangles are similar is often an exercise in applying one of the many theorems young geometers memorize, like the AA similarity criteria. But proving that the criteria themselves are valid from basic principles is a great...

Snail Pace
Slow and steady wins the race? In the assessment task, scholars calculate the rates at which different snails travel in order to find the fastest snail. Hopefully, your class will move much more quickly in finishing the task!
