In this math lesson, learners apply measurement skills to determine, in dollar bills, the capacity of a suitcase.

In this math lesson, learners apply the concepts of ratio and proportion to the capture-recapture statistical procedure.

In this math lesson, learners measure, predict and determine the frequency of an event as it relates to how close Whirlybirds land to a target.

In this activity, learners make an electromagnet motor to demonstrate the most basic method of changing electrical energy into mechanical energy.

In this math lesson, learners identify the likelihood of an event by using a walk-on probability scale.

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

In this math lesson, learners arrange pattern blocks to create tessellations and to explore geometric patterns. Learners first explore making patterns with a variety of pattern blocks.

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

In this activity, learners play an evolution card game to see how selective pressures can affect an organism's evolution.
