Use this applet to create patterns to cover the screen using regular polygons.
Pre-K-2, 3-5, 6-8, 9-12
Use this tool to create a spinner to examine experimental and theoretical outcomes.
3-5, 6-8
This applet allows you to examine various two-dimensional figures to determine which ones can be folded into a cube.
6-8
Use this tool to determine how the length of the base and the height of a
triangle, parallelogram, or trapezoid can be used to determine its area.
Pre-K-2, 3-5, 6-8
This tool allows you to create any geometric shape
imaginable. Squares, triangles, rhombi, trapezoids and hexagons can be created,
colored, enlarged, shrunk, rotated, reflected, sliced, and glued together.

In this lesson,
students learn the definition of like terms and gain practice in identifying
key features to sort and combine them. Most middle school students are adept at
recognizing the nuances of dress and manner that identify groups and cliques
among their peers. This lesson applies the observation and sorting skills that
students already possess to the important task of identifying and combining
like terms. Students will play the game Ker-Splash and derive rules for working
with like terms.

Studying the behavior and motion of dinosaurs is obviously a
challenge since these creatures are extinct. If researchers wish to examine the
running velocity of a dinosaur, they must instead consider other evidence of
dinosaur motion and make an indirect estimate. In this lesson, students will
play the role of researchers who field test the Alexander Formula—a formula that uses paleontology data to estimate dinosaur running
velocities. Students will serve as human analogues, making measurements on
themselves, computing predicted running velocities using the Alexander Formula,
and calculating their actual running velocities. They will then evaluate the
accuracy of the formula by comparing estimated and actual running velocities
for the class.

The lesson is based upon Aesop’s fable,
“The Crow and the Pitcher,” and involves students making predictions and conducting
experiments to determine how many pebbles the crow would need to add to the
pitcher in order to bring the water to drinking height. In the course of the
investigation, students gain a real-world understanding of linear functions and
such concepts as slope,
y-intercept,
domain, and range.

In this lesson, students will play card
and computer games by adding fractions to make 1. Students will determine how
the fractions are related, by first determining what they have and then how
much more is needed. Through different interactive games, students will utilize their skills and build upon them to expand their
understanding of fractions. Students will be able to determine common
denominators and other strategies to add fractions with like and unlike
denominators.
3-5, 6-8
In this lesson, students use their previous knowledge of
multiplication to identify factors and form products. Students will use Illuminations’
Times Table to identify various patterns in a multiplication table. They will then
play the Multiple Factors Game and Times Square to reinforce their
understanding of factors and multiples.
