One of my favorite DIY projects this summer has been the Flip Chute. As soon as I saw it my mind began to race with ideas for the cards to go with it! Knowing that my kids will love this activity I've been saving my cartons to make multiple chutes.
If you click on the Flip Chute link you will see a video tutorial by Julie from Make, Take and Teach. A couple tips from my experience -- cut a cardboard pattern for your rectangles, trace onto the carton, and use an x-acto knife to cut it out. Don't worry about getting your covering on perfectly. I used duck tape and it was easy to cut small pieces and patch areas that weren't totally lined up. Also, measure and cut the card stock to the dimensions of your rectangles. That makes your cards slide through better (my first ones were a little too narrow). Last, try cards after taping your card stock and before covering the carton -- just in case you need to adjust a bit.
And now for some cards to use with your new flip chute! You can certainly just use index cards, but I wanted a template that I could use for many different sets to go with standards I'm teaching. I copy them back-to-back on card stock, laminate, and they are ready to go. You can get this starter set for your own classroom here. Enjoy!
