Strengthen Addition Through the Relationship with Subtraction

One powerful way of building proficiency in the addition concept is by exploring the relationship between addition and subtraction. This missing addend worksheet incorporates the missing addend addition sum plus asks students to show the matching subtraction sum. This worksheet reinforces addition skills and encourages students to utilise the inverse relationship between addition and subtraction as a strategic approach to three-digit addition.

An answer key is included with your download to make grading fast and easy! 

Tips for Differentiation + Scaffolding  

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

• Math rotations
• lesson exit ticket
• fast finisher activity 
• homework assignment
• whole-class review (via smartboard)

For fast finishers, write some additional missing addends on the whiteboard in the thousands and have them work it out with the matching subtraction sum.

For students who need extra assistance, allow them to use manipulatives or provide them with two-digit addition sums initially.
