Missing Addend Information

Even though I know that you have this information in your child's math notebooks, I wanted to take a few minutes to send examples of how the children are expected to answer this type of math question.

Example One:

There are 2 birds in the tree. SOME MORE birds flew into the tree. Now there are 7 birds in the tree. How many birds flew in the tree?


How to draw it:

The children would be expected to draw two birds to represent the two that were already in the tree...then a "plus"...then A BLANK to represent the amount of birds they don't know yet...then an "equal sign"...and then the number 7.


They would next go back to "fill in their blank" with birds until their birds EQUAL 7.


They would then write their equation to match.

2 + ___ = 7


They would then go back to solve the "mystery."

2 + 5 = 7.

Example Two:

Mom put SOME cookies on my plate. Dad put 2 more cookies on my plate. Now there are 6 cookies on my plate. How many cookies did mom put on my plate?


How to draw it:

The children would be expected to start with A BLANK (because their first piece of information is the part that they don't know). They would then put a "plus." They would then draw the two cookies that Dad put on the plate...and then an "equal sign" followed by the number 6.


They would next go back to "fill in their blank" with cookies until their cookies EQUAL 6.


They would then write their equation to match.

_____ + 2 = 6


They would then go back to solve the "mystery."

4 + 2 = 6

In Conclusion...

It is important that their pictures "show understanding" of the math problem given. Their "blank" represents the piece of information that they do not know and should be shown in the correct location. We encourage the children to read the problem one sentence at a time and draw pictures to match as they go. This seems to help. I know that this can be a difficult concept. This skill will continue throughout the remainder of the school year.

I wanted to take a few minutes to send these examples so that you could practice over the break as needed, based on your child's math update sent earlier this week.
