Here are some notes for pupils about how to convert between fractions, decimals and percentages. The idea is that they can add examples to them in the blank space around and inside the triangle:

Here is a grid-filling exercise where they can apply the ideas in the notes. Forming groups of 4 to discuss their answers, mark correct if they all got the same answer or discuss who is right if they have different answers is a nice way to mark this activity.

Thank you so much for this “easy to learn” idea! I teach Algebra I/Special Education (HS) and am always looking for ways to remediate skills my students somehow missed in their earlier years! This is perfect!!

I really like your diagram on converting fractions, thanks for sharing! One of my friends is building a 3D math adventure game that covers fractions as well, http://www.mathbreakers.com. If you get a chance, check out the trailer & let me know what you think!
