Estimating Pi as a Length
In this pi learning exercise, students evaluate the curve of a quarter of a circle. They analyze the length of the curve, and explain that if the area under the curve is equal to pi, the length of the curve above is also equal to pi....

Popcorn Math
Everyone loves popcorn! Use this treat to teach math concepts including place value, estimating, graphing, and volume. Eight possible activities are included, and they can be modified to fit all grade levels.
Curated OER
One Hundred Things
Learners practice estimating by handling items in groups of ten. They visualize how much space 100 items, such as pennies, peas, or beans, will take up after holding 10 of them. Students measure the difference in volume between 10 and...
