In our school district we are expected to assess our students in trimester 2 on missing addends, but our current curriculum does not have any lessons to teach this concept.
After I looked over our district assessments and what they expect our students to do, I created several worksheets for practice in each area:
1. Write and solve addition and subtraction problems with missing numbers.
2. Read and solve addition and subtraction WORD problems with missing numbers.
3. Solving addition and subtraction number sentences with missing numbers.
4. Match a missing addend number sentence with the correct word problem.
This packet provided my students extra practice with the types of problems they would be seeing on their district assessments.
I also used some of the sheets as formative assessments throughout my lessons. These sheets could also be used as summative assessments as well.
