This is a 2-page worksheet in which students will glue the missing addend puzzle piece in the appropriate square needed to complete the addition sentence. 

When the student correctly identifies all 9 missing addends, they will see a fun outdoor scene on their worksheet! 

Through this activity, students demonstrate the operations ability to complete addition equations up to 200. 

Missing Addend Worksheet: Scaffolding + Extension Tips 

In addition to individual student work time, use this worksheet as a:

• Math center activity
• Post-lesson exit ticket 
• Homework assignment
• Whole-class review (via smartboard)

Got fast finishers? Students who need a challenge can create their own missing addend puzzle board working on addition within 1,000.  

Students who need extra support can refer to a number line or use manipulatives to help them visualize the missing addend. Or move them down to the level 1  or 2 worksheets (see bottom of page).
