Mummy Number Line

This interactive website is great for primary-age students to learn subtraction with a number line. Students are given subtraction problems and a number line to help them determine the difference. When students correctly answer the question, the mummy begins to unravel. If the answer is incorrect then the mummy keeps the wrap. Using the number line allows for students to demonstrate how to subtract and what is happening when they are subtracting.
