Use tiles to represent variables and constants, learn how to represent
and solve algebra problem. Solve equations, substitute in variable
expressions, and expand and factor.
Pre-K-2, 3-5, 6-8, 9-12
Need a pentagonal pyramid that's six inches tall? Or a number line that goes from ‑18 to 32 by 5's? You can create all those things and more! Place the images you want, then export it as a PDF or as a JPG image.

This tool allows you to manipulate various geometric solids and investigate their properties.
3-5, 6-8, 9-12
Using this interactive tool, you can practice arithmetic and algebraic skills, and investigate the important concept of equivalence.Pre-K-2, 3-5, 6-8, 9-12
Use this tool to create a spinner to examine experimental and theoretical outcomes.
9-12
Explore the amplitude, period, and phase shift by
examining the graphs of various trigonometric functions.
6-8, 9-12
In this lesson, students will explore reflections,
translations and rotations. Students participate in a modeling activity where
they will learn the rules for translations and reflections. Then students
will practice using these transformations, as well as explore the rules for
rotations, in the game
Flip-n-Slide on Calculation Nation®.
9-12
In this lesson, students will manipulate three paper circles
to explore four circle theorems. Using paper folding allows the lesson to be
more accessible to kinesthetic learners.
6-8, 9-12
In this lesson, students will develop an understanding of the Fibonacci Sequence (and its connection to Golden Rectangles), Golden Ratio, Golden Rectangle, and the term
ratio (as it applies to rectangles). Students will use tools and construction techniques to demonstrate geometry prowess and be able to observe the Golden Rectangle in nature and in the classroom.
9-12
This lesson allows students to explore the idea that
rainforest deforestation is occurring at an exponential rate. Students will use
provided research about Amazon deforestation and conduct their own research to
determine whether deforestation is occurring exponentially.
