This sample contains a few slides for you to try. The full version contains 20 slides designed to provide students with extra addition/subtraction practice. The operations are within 10, except for a few challenging ones that go up to 13. I use it in my class as a game with buzzers. Students buzz when they think they know the answer, and they respond before I show them the correct answer. This presentation also has fun animal sounds clips which my students find hilarious. The sounds play automatically after the correct answer is revealed. You can try this short version for free. If you like it, you may want to purchase the full version. Look for it in my store.
