Missing Addends

The directions on this activity tell learners to put the missing numbers in the box. They will use their algebraic reasoning to determine the missing addend for 18 different addition problems. 

In this math worksheet, student find the missing addend in 28 single and double digit addition problems and write the corresponding subtraction problem.

Using images helps budding mathematicians grasp difficult subtraction concepts. In this set of three word problems, they examine sets of objects which are reflected in each scenario. To approach subtraction in a more accessible way, the...

Introduce scholars to the commutative and additive identity properties of addition with two sets of practice problems. First, they fill in the missing addend by choosing from a group of three possible answers. These six addition...
