Curated OER
Reflection
Students examine how some transformations, such as reflections and rotations, do not change the figure itself, only its position or orientation.
Curated OER
Perimeter, Area and Volume
Middle schoolers compute area. In this perimeter, area and volume lesson, students examine given objects and determine the perimeter, area, and volume of each.

How Big is a Lunar Crater?
For this lunar crater worksheet, learners use an image taken by the Lunar Orbiter spacecraft to find the scale of the image and determine the diameter of the lunar crater Tycho. They also find the size of the smallest and largest...
Curated OER
Similarity and Congruence
Students determine that two figures are similar or congruent by
investigating figures that are similar and figures that are congruent. They prove that two figures are similar or congruent by using definitions,
postulates, and theorems.
Curated OER
How do You Stack Up? Revisited
Students estimate the thickness of coins. In this stack up lesson, students stack pennies, nickels, dimes and quarters. They calculate and record the thickness of each coin. Students stack coins and estimate the height of the stack.
Curated OER
Craters on the Moon
In this moon craters worksheet, students use a high resolution image of the lunar surface and calculate the image scale in meters per millimeter. They use the image scale to find the largest crater in the image, the smallest crater, the...
