This is part of a 5 day series of worksheets that gets students thinking of the number sentences in fact families differently. The expression is may be on the right or the left with the sum or difference also being on the right or left.
The last section of each page also has them completing 2 digit fact families which really helps expand the role of the knowledge of how fact families worth beyond basic facts.
This series also helps build and reinforce balancing equations knowledge and helps students get out of the mindset that after the equals sign they should always expect to write the "answer" to a "problem." It gets them thinking more about how the equals sign means balanced and equal on each side.
