Are you looking for a purposeful warm up or number sense activity?! LOOK NO FURTHER! This download is perfect for partner work, independent handouts, or centers. It's also a learning tool! Have students bring their page to a group or carpet time and have conversations about HOW they KNEW the answer was correct or incorrect. I love to hear how different all of their reasoning is!

Students are asked to look over the equations and determine if the answer is correct or incorrect. The download comes with a page for addition and subtraction 1-20 and the answers. 80 pages total.
Fluently add and subtract within 20 using mental strategies. By end of Grade 2, know from memory all sums of two one-digit numbers.
Understand the meaning of the equal sign, and determine if equations involving addition and subtraction are true or false. For example, which of the following equations are true and which are false? 6 = 6, 7 = 8 - 1, 5 + 2 = 2 + 5, 4 + 1 = 5 + 2.
Add and subtract within 20, demonstrating fluency for addition and subtraction within 10. Use strategies such as counting on; making ten (e.g., 8 + 6 = 8 + 2 + 4 = 10 + 4 = 14); decomposing a number leading to a ten (e.g., 13 - 4 = 13 - 3 - 1 = 10 - 1 = 9); using the relationship between addition and subtraction (e.g., knowing that 8 + 4 = 12, one knows 12 - 8 = 4); and creating equivalent but easier or known sums (e.g., adding 6 + 7 by creating the known equivalent 6 + 6 + 1 = 12 + 1 = 13).
