Want to use Illuminations resources but don't know where to begin? We've got you covered!

Product Game: The Product Game is a fun, interactive game that exercises your skill with factors and multiples.

Pan Balance: Use this tool to strengthen understanding and computation of numerical expressions and equality. In understanding equality, one of the first things students must realize is that equality is a relationship, not an operation. Many students view "=" as "find the answer." For these students, it is difficult to understand equations such as 11 = 4 + 7 or 3 × 5 = 17 – 2.

Fraction Models: Explore different representations for fractions including improper fractions, mixed numbers, decimals, and percentages. Additionally, there are length, area, region, and set models. Adjust numerators and denominators to see how they alter the representations and models. Use the table to keep track of interesting fractions.

Turtle Pond Guide a turtle to a pond using computer commands, number of steps, and degrees of movement.

Cube Nets: A net is a two-dimensional figure that can be folded into a three-dimensional object.

Deep Sea Duel: Okta challenges you to a duel! That crazy octopus wants to play you in a game where the first person to choose cards with a specified sum wins. You can choose how many cards, what types of numbers, and Okta's level of strategy.

The Factor Game is a fun, interactive game that exercises your factoring ability. You can play against the computer or against a friend.

Tessellation Creator: A tessellation is a repeating pattern of polygons that covers a plane with no gaps or overlaps. What kind of tessellations can you make out of regular polygons?

Isometric Drawing Tool: Use this interactive tool to create dynamic drawings on isometric dot paper. Draw figures using edges, faces, or cubes. You can shift, rotate, color, decompose, and view in 2‑D or 3‑D. Start by clicking on the cube along the left side; then, place cubes on the grid where you would like them.

Geometric Solids: This tool allows you to learn about various geometric solids and their properties. You can manipulate and color each shape to explore the number of faces, edges, and vertices, and you can also use this tool to investigate the following question: For any polyhedron, what is the relationship between the number of faces, vertices, and edges?
