Beginning with a word problem that poses the question of making groups of 10 pennies to translate into a single dime, pupils are challenged to make sense of the amount of dollars 33 cents is in expanded form.

Mathematicians go on a virtual shopping trip in an interactive designed to boost the concept of estimation. Scholars read and answer five questions—multiple-choice, true or false, and a discussion—with help from a drag-and-drop shopping...

Even money states that the resource is good to use. Scholars manipulate an interactive to adjust the portion of a graph to the left of the y-axis. The interactive allows them to switch between even and odd modes that show the right side...

In this daily math problem activity, students complete three activities that help them compare and order numbers. Students show their work using pictures, numbers, or words and may use cubes, number lines or hundred boards for help.
