Students read "The Magic School Bus in the Human Body" and discuss the importance of maintaining a healthy body. They create a hinge and joint paper skeleton, follow the journey of a hamburger through the digestive tract, jump rope and...

Is there a relationship between height and the number of siblings? Classmates collect data on their heights and numbers of brothers and sisters. They apply statistical methods to determine if such a relationship exists.

There's nothing quite like a glass of ice-cold, freshly squeezed lemonade. Lesson seven of this series explains how the water humans need to survive can come in many forms. Teach your class about how much water humans require every day...

Triangle centers and the segments that create them easily become an exercise in memorization, without the help of engaging applications like this instructional activity. Here the class investigates the measure of center that is...

Speed up your scholars' understanding of ratios. Class members compare ratios related with speeds presented in different representations. They then use the unit rates to make the comparisons. 

Using the provided blank face template, learners of any age draw to learn how to create proper facial proportions. This lesson focuses on two dimensional facial proportions, how to estimate those proportions, and drawing techniques. If...

Groups collect data describing the number of times a bag of microwave popcorn pops at given intervals. Participants discover that the data fits a normal curve and answer questions based on the distribution of this data.

Approach the lesson from the right angle. A discussion-based lesson leads helps learners understand angles in terms of rotation. Individuals use manipulatives to explore the properties of angles and learn how to name them. The lesson is...
