Today when we did d.i.m.i.c we had someone to come in and help us. Our problem was " A child ate 100 cookies in 5 days. Each day they ate 6 more than the day before. How many cookies did they eat on the first day?"
My group worked it out by using the guess and check strategy. But first, we tried taking 6 away from 100 but that didn't work. We started with 15 and added 6 five times but after adding them together it was too high so then we tried 5 and it was too low so we tried 10 but that was too high. The last one we tried was 8 and it was correct. The people in our group were Jessica, Ailie Shyla and me. this was our paper. the numbers with the circle were the correct awnsers
