My kiddos LOVE to do these. It is so fun and engaging. I use finger flashlights from Amazon (https://www.amazon.com/Tzou-80-LED-Finger-Lights/dp/B008JE5KZY/ref=sr_1_2?ie=UTF8&qid=1477177712&sr=8-2&keywords=finger+flashlights) $10 for 80!
The powerpoint just needs a click to move through. The first slide is the sight word for them to read. The second slide has one letter appear at a time for them to spell.
It includes Fry's first 100 words.
Hope you enjoy!
