Get your students comfortable with relating addition and subtraction facts. This product has an activity and worksheets to provide plenty of practice.
Fact family example mini-poster
Activity: Write a fact family to match a picture
These could be used as task cards for centers, small groups, or early finishers. They could also be used as a solve-the-room activity. Just hang the cards in various spots around the room. Students then walk around with their recording sheets and solve.
12 picture cards
These could be used for practice, homework, or formative assessment.
3 sheets where the numbers are given: students write the fact family for the set of numbers.
3 sheets with pictures: students write a fact family to match the picture.
3 sheets that have fact families with missing numbers: students fill in the missing numbers.

Common Core State Standards Addressed:
CCSS.Math.Content.1.OA.B.3Apply 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.B.4Understand subtraction as an unknown-addend problem. For example, subtract 10 - 8 by finding the number that makes 10 when added to 8.
CCSS.Math.Content.1.OA.C.6Add 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.2.OA.B.2Fluently add and subtract within 20 using mental strategies.2 By end of Grade 2, know from memory all sums of two one-digit numbers
