Missing Numbers & a Freebie

One skill that has been particularly hard this year for many has been finding missing addends and subtrahends. It feels like we have been reviewing it over and over again.

We have done the activities where use a balance and cubes to figure out the missing number.
We have used hundred charts as a game to pick any number then your partner does and figure out how to get between the two numbers.

I finally put together a packet of some of the other activities we have been doing in math centers to help with this skill.

The packet includes 6 activities. Each activity comes in an addition version and subtraction version. Within both of the addition and subtraction versions are versions working with numbers up to 20 or numbers up to 100.

Also while making this I was inspired to work with ten frames and came up with this freebie. 

It is meant to work with the K.OA.4 standard but can still be helpful with first graders.
