Not the greatest picture (sorry!)
Another way to just mix up basic addition! The kids seem to love any activity involving a dice or a spinner. You can get these spinner boards in packs at Lakeshore Learning.
It's just as simple as it looks with a spinner, addition paper, and two bowls with different objects.
It's fun to switch out the objects throughout the year and relate it to the current season, holiday, or unit that you're studying. I put this out in late spring hence the frogs and butterflies. Switching the type of addition paper to a different format or using graph paper keeps them coming back over and over again!
