Mathematics Grades 7-9

These colourful, visual representations of numbers were inspired by a digital clock. The images get more interesting as the numbers increase, so take your time or use the forward button to move on. Click 'About' on the bottom left to get a deeper understanding of the process.

Explore this video and the interactive learning objects to explore the mathematical relationships in three term ratios. The subject of photography is used to connect mathematical concepts with real world problems.

This site has activities for several different math operations. You can practice your times tables, halves, doubles, square numbers and more.

This interactive resource lets students explore the order of operations (brackets, exponents, multiplication, division, addition and subtraction).

The activities explore the calculations of squares and square roots to solve equations involving right triangles. Explore both the video and the interactive components of this resource.

Play a fast-paced video game involving reasoning about ratios and equivalent ratios. This game from Math Snacks focuses on using ratios to complete a potion recipe in order to defeat your foe.

This video tells the story of physicist Enrico Fermi, who was very good at making fast estimations of big number problems. Learn how he used the power of 10 to make reasonable estimates of large numbers (like how many piano tuners in the city of Chicago).

Math is full of symbols: lines, dots, arrows, English letters, Greek letters, superscripts, subscripts ... it can look like an illegible jumble. Where did all of these symbols come from?
