These are super easy for the kids to make! I just cut a bunch of 3"x 3" squares, and had the kids cut off the corners and "round" TLC style. (I didn't draw dotted lines for them - too much work! I just did it here for example's sake!) The cone I just drew on a paper that was 4" x 3". I tried having the kids draw their own cone on the paper, but for whatever reason it was harder for them than I thought! I had them glue it on a half sheet of 12x18 white paper. When I tried it without the paper background, there was glue everywhere, the ice cream scoops overlapped so much you couldn't read their math problems, etc.
Then I made them pick a number between 5 and 20 (or you could have them roll a die) and take that many unifix cubes, and make them into a "train". In this case, the student chose the number 12. Then they break their train into 2 pieces. Here, the student broke his into 7 and 5. This is the math problem they write on the ice cream. 7+5=12. Put your train back together, and break it a new way. Ex: 2+10=12.
I think they turned out quite nice! They kids really liked trying to figure out what flavor scoops of ice cream they were using - "I'm picking green because I like Mint, I think the pink is bubblegum!"
All this ice cream talk is making me want to scoop a bowl for myself! Lol!
Have a great summer!
