1st Grade Common Core Word Problem Worksheets Review- Addition and Subtraction 1.OA.3, 1.OA.5. 1.OA.6 and 1.OA.7

**In the yearlong progression, these worksheets were designed to be taught in the 2nd nine weeks; however, they could be used any time after you have taught the review concepts. You could also use the front of the worksheets in isolation.

The following attachment is a five day series of worksheets, which includes a test for Friday. Each day has two worksheets, designed to be copied front and back. The front sheet of each day is the focus standard of the week and the back page has concepts previously taught.

The focus concepts this week are:

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.C.5 Relate counting to addition and subtraction (e.g., by counting on 2 to add 2).

CCSS.Math.Content.1.OA.C.6 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).

CCSS.Math.Content.1.OA.D.7 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.

The review concepts on this week of worksheets are standards 1.0A.4, 1.MD.3 and 1.NBT.1

Each set of worksheets incorporates word problems and place value every day.
