This is a sort game for students to use during centers. Students sort equations by true/false. Equations use alternate formats (10 = 5 + 5 OR 5 + 5 = 10) and are differentiated by page. The first 6 pages are simple true/false equations with sums totaling from 6 - 13. The next 2 pages are expanded form equations, focusing on combinations of 10. The final 4 pages are multi-expression equations. These pages could be printed on different colored paper to differentiate levels of difficulty.
