This app is designed to help students master the following Common Core Math Standards:

CCSS.MATH.CONTENT.1.OA.B.3 - Apply properties of operations as strategies to add and subtract.2 Examples: If 8 + 3 = 11 is known, then 3 + 8 = 11 is also known. (Commutative property of addition.) To add 2 + 6 + 4, the second two numbers can be added to make a ten, so 2 + 6 + 4 = 2 + 10 = 12. (Associative property of addition.)

CCSS.MATH.CONTENT.1.OA.D.8 - Determine the unknown whole number in an addition or subtraction equation relating three whole numbers. For example, determine the unknown number that makes the equation true in each of the equations 8 + ? = 11, 5 = _ - 3, 6 + 6 = _.

CCSS.MATH.CONTENT.1.OA.C.6 - Add and subtract within 20, demonstrating fluency for addition and subtraction within 10.

First grade students need scaffolded experiences to develop problem these solving skills. This app includes 240 equation cards that are presented in 6 levels of increasing complexity.
