This is a great, quick practice for simplifying ratios to basic ratio that makes things a little more fun than just another worksheet. Students will practice identifying ratios from real life situations, writing part to part and part to whole ratios, and then simplify ratios. It allows students to choose their own problems and to also check their own work. Thus providing excellent differentiation and scaffolding. Students choose three problems in a row to solve and find the corresponding answers in the grid below. They color the problem and the solution the same color to make it easy for the teacher to quickly check their work. If more practice is needed, they can always go for blackout! My students love these tic-tac-toes and beg for them daily! I often give them as formative assessments at the end of lessons and the students don’t even realize they are being tested!
