I'm working with a little girl who is learning how to subtract.
The touch math strategies were very successful in helping her learn to add, so we are continuing with those materials and cues. However, when she was learning to add, she
had already mastered the skill of counting up. She has not yet learned how to consistently and accurately count backwards from 20. So while she is learning the concept of subtraction with differences from 5 and manipulatives, we are also working on counting backwards from 20.
I created a simple power point that she likes to "play" when we practice. I have her manually click to forward the slides. You can download the manual click power point here. I also added an automatic slide transition for those of you who may want to use this in the classroom. You can download the automatic transition power point here.
In addition to using the power points during our tutoring session, her mom is also helping her count backwards during the many opportunities to wait during the day. They count backwards in the grocery store line, while waiting for her brothers at baseball practice, while the microwave is heating something, while a DVD is loading, etc. She has found lots of times during the day to practice with her!
