Examine the unique graphs coined broken-line graphs. Using the phase change of water for data, learners answer questions related to the temperature and energy at different times in the cycle of the phase change. Questions focus on the...

Fifth graders construct data graphs based upon sets of data. In this graphing lesson, 5th graders read the text If the World Were a Village and discuss how types of graphs accurately represent a large population. Students construct their...

Eighth graders experiment to determine the number of drops of water a heads up penny hold. They create a stem and leaf graph of the class results and use the data for further experimentation on a tails up penny.

Students make a graph identifying the immigration of Mexicans to the US. In this algebra instructional activity, students practice graphing as they review different trends in immigration over the past 100 years. They interpret and...

Young scholars excavate an artifact. In this archaeology lesson, students get a bucket filled with dirt and a broken up artifact. They work in groups to take it out and to find what its purpose was. 

Programming a robot is a mathematical task! The activity asks learners to examine the process of programming a robot to vacuum a room. They use a coordinate plane to model the room, write equations to represent movement, determine the...

Circles are the foundation of many geometric concepts and extensions - a point that is thoroughly driven home in this extensive unit. Fundamental properties of circles are investigated (including sector area, angle measure, and...
