In this math lesson, learners use hinged mirrors to discover that regular polygons are composed of triangles tessellating around a center point.

In this math lesson, learners apply the concepts of ratio and proportion to determine the length of the Statue of Liberty's torch-bearing arm.

In this math lesson, learners use a variety of manipulatives to explore spatial relationships of squares and their transformations.

In this lab activity, learners explore how to initiate a density current. Learners measure six flasks with different concentrations of salt and water (colored blue).

The major goal of this math lesson is to have learners collect data from a variety of experiments, determine what models best fits their data, and explain why their models are best.

In this math lesson, learners analyze the density of liquids in order to explore linear functions.

In this math lesson, learners explore polynomial and rational function patterns.

In this math lesson, learners compare products to determine the best product.

In this math lesson, learners estimate distances between landmarks and use a map and scales to determine the actual distances.

In this math lesson (on Page 13), learners predict and simulate the likelihood of an event occurring.

In this math lesson, learners extend their understanding of basic probability concepts as they learn to name all of the possible outcomes of an event as well as ways to express the likelihood of such

In this math lesson, learners construct box-and-whisker plots to analyze and compare data sets. Learners investigate whether or not long-legged people run faster than short-legged people.

In this "Sid the Science Kid" activity, learners use their bodies to measure a room. Instead of inches or feet, how many kids does it take to measure the length of a room?

In this "Sid the Science Kid" activity from Episode 103: Enough With the Seashells!, learners practice estimating numbers of objects (like shells) and then check their estimates by counting.

In this math lesson, learners explore the relationship between the thickness of a spaghetti bridge, the length of the bridge, and the amount of weight that can be supported by the bridge.
