In this article, we have focused on worksheets for the addition of single and double-digit numbers. We have also included examples where the concept of “regrouping” (carry-over) is used. Below, we have a collection of 10 printable worksheets in JPEG and PDF formats for free download. Please feel free to share this worksheet for non-commercial educational purposes. These worksheets teach addition using pictures as a strategy. This is compliant with CCSS2.OA.B.2, CCSS1.OA.C.6, CCSS1.NBT.C.4, and CCSS 2.NBT.B.5 standards, which are used in most schools in the USA.

Common Core State Standards
- Standard CCSS2.NBT.B.5: Fluently add and subtract within 100 using strategies based on place value, properties of operations, and/or the relationship between addition and subtraction.
- Standard CCSS1.NBT.C.4: Add within 100, including adding a two-digit number and a one-digit number, and adding a two-digit number and a multiple of 10, using concrete models or drawings and strategies based on place value, properties of operations, and/or the relationship between addition and subtraction; relate the strategy to a written method and explain the reasoning used. Understand that in adding two-digit numbers, one adds tens and tens, ones and ones; and sometimes it is necessary to compose a ten.
- Standard CCSS1.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).
- Standard CCSS2.OA.B.2: Fluently add and subtract within 20 using mental strategies. By end of Grade 2, know from memory all sums of two one-digit numbers.
