For whom does the bell fit? Pupils begin by working in groups gather data on three different variables. They then determine the mean and standard deviation of each data set and create bell curves. To finish, they answer guiding questions...

Otters swim through numerical gates carrying multiplication equations with a missing factor. By choosing the gate with the correct missing factor, players make the otter swim faster in the online game.

Upper elementary and middle school scholars study the economic factors that caused so many Arkansans to migrate to different parts of the country looking for work. Use this history lesson plan to help your charges gain a better...

The title says it all: Could King Kong exist? Investigate how increasing the dimensions of an object affects its surface area and volume to mathematically conclude whether a creature with the weight and height of King Kong could actually...

Streets, bridges, and intersections, oh my! Parallel lines and transversals are a present in the world around us. Learners begin by discovering the relationship of the angles formed by parallel lines and a transversal. They then...

Liability, deductible, premium ... what do these words mean, and how do they relate to insurance? Scholars complete a pre-test, matching vocabulary activity, and insurance timeline worksheet and become familiar with these terms. Next,...

What do a zoo, snow, and a moving particle have in common? The six free-response items from the 2010 AP® Calculus BC exam allow teachers and pupils see how items may show up in context. Three of the questions are from only the BC portion...

Identifying patterns is a crucial skill for all mathematicians, young and old. Explore the multiplication table with your class, using patterns and symmetry to teach about square numbers, prime numbers, and the commutative and identity...

Once I told a chemistry joke, but there was no reaction. Get young chemists involved in changes and reactions with a presentation that begins with physical and chemical changes and chemical reactions. It moves on to chemical...

Let's go fishing together. The lesson looks at the giant catfish from two perspectives. Mathematically, pupils develop a scatter plot and a best-fit line for the size, while others take a scientific look at the reasons for their...

Explore linear inequalities in a contextual situation. Using data from the first lesson of the series, groups graph linear inequalities to predict future shooting percentages. Their work focuses on defining regions and relating their...

For this place value worksheet, young scholars circle groups of "ten cubes" and write how many tens they counted all together. Students are grouping cubes in ten's.

Students brainstorm healthy food choices. In this health science lesson, students calculate how much of each food group they need daily. They plan a menu based on the "MyPyramid for Kids" food guide.

If at first you cannot graph, substitute. The lesson introduces the substitution method as a way to solve linear systems if the point of intersection is hard to determine from a graph. The 28th installment of a 33-part series finishes...

As an introductory activity, young statisticians measure their heart rate at rest and after exercise and compute the mean and median, and create a box & whisker plot.  This is followed by watching a video (that no longer seems...

In this grouping activity, students observe models of groups. They identify the number in each row, the number in each column and then identify the total in the group. This one-page activity contains four grouping problems.
