Idea details:

My brother and I collected returnable recycled bottles to give to a charity.

We sorted our bottles into different bags of 100. Some bags were for 10 cent returns and some for 5cent. The 10 cent bags were worth $10.00 each (100 x 0.10). The 5 cent gas were worth $5.00 each.

We ended up after 6 months with 23 $10 bags and 14 $5 bags. This gave us a total of: $230+ $70=$300 for our donation. We practiced adding and multiplying as we gathered up bottles. My brother made a graph each week to count up what we saved. The garage was very full at the end! Mom borrowed our Uncle’s truck to take them to the recycling depot. We also learned about giving.
