This file contains a PowerPoint with 77 slides that can be used as assessment or for practice. These slides cover adding or subtracting the numbers 0,1,2,3,4 or 5 (9 + 5 is the largest addition problem). Students will see the addition or subtraction fact and be given 3 second to answer before the correct sum or difference appears. I've thrown in a few motivational slides here and there to encourage them to keep going.
I wonder if it has to do with format. This was made on a pc...I just checked the file again, and when I am in slideshow view mode, the problem shows up, but the answer doesn't until I click my mouse an extra time. Are you on a pc or a mac? Let me know. I don't want you to end up with a product that doesn't work correctly for you.
