This product is a Power Point that goes through Subtraction Facts within 20. Each slide is set for 3 seconds and is on auto play. The facts start at "0 - 0 =" and run through all of the facts ending at
"20 - 20 =." The subtraction problem is on one slide and the answer is on the other slide. There are a total of 466 slides.
These Power Point slides are set up like flash cards. Students can look at the slide, read the problem, and give the answer. I use the Power Point whole class using my document camera. I like using it for my transition times, cool down time, and as a quick filler. I also like having students get out their whiteboards and see if they can give the answer before it is given. If you don't have a document camera or a way to have students view the Power Point whole class it can be used for independent practice on individual computers.
I find Power Points to be a great way to squeeze in a couple extra minutes of learning time. They are a tool I use regularly. Please visit my site for other Power Points or to view my other products.
