While at Dollar Tree (where else would I be), I found magnetic fishing games. Each game comes with a fishing pole that has a magnet on the end of the line and three little sea creatures that also have magnets.
The idea is to go fishing for two numbers and write an addition fact using those numbers, then write a related subtraction fact. There you have it- Fishin' 4 Addition!
I created a recording sheet. Click here for the printable version!
You could tweak this game and use the numbers they catch for greater than/less than, odd/even, or making two digit numbers and place value activities.
