Is that a problem for your kids? Do they just guess whether they should add or subtract? I decided to let my kids practice listening to the problems and just decide on which action they should do.
They don't even have to find the answer (although you could if you wanted to).
I made these paddles with add + on one side and subtract- on the other. I used two small paper plates with the stick in between them. The plates spoon each other so they are easier to store for another time. I hot glued a craft stick to them.
Read the problems in the file attached below. Let them hold the paddle to their chest so their neighbors can't see how they voted. And you can easily get a feel for their understanding.
This can be practiced over and over
until you think they finally get it.

Remember if you grab them, to leave me a comment. I'd love to hear if this is a problem for your kiddos and if you think this would work for them too.
