A change is coming. Pupils use unit cubes to investigate how changes in the length, width, and/or height affects volume and surface area. They extend the results to write and test predictions on the effect of changing multiple sides on...

The ninth installment of a 21-part module has pupils compare integers and rational numbers in decimal and fraction form. They match stories to number lines and compare values in the stories.

Students participate in a physical education activity, Mission Possible, where they attempt to steal a jug of jewels. They must successfully overcome five challenge areas to complete the activity. Students develop cooperative...

Try your hand at scale models. Scholars create a scale model of an object using a scale factor of their choice. As part of the project, they give presentations on their processes and calculations. This is the last installment of the...

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. 

Sixth graders explore the scientific method by conducting an in class experiment. In this scientific averages lesson, 6th graders discuss the concept of the scientific method, and define the different mathematical averages, mean, median...

Two methods are always better than one! The eighth installment in this series asks pupils to convert decimals to fractions using two approaches. Individuals first use the more traditional approach of long division and then use reverse...
