The 100th day of school is upon us and Caleb was tasked to collect 100 small things in a non see-through bag for his classmates to shake about and guess its contents.
Caleb picked OmniPod batteries.
Each Pod has 4 small batteries. Getting the batteries out of Pods is not necessarily a speedy process. This all lent nicely to doing some math.
- How many Pods do we need to pry open to get 100 batteries?
- We have 36 batteries. Have we collected more or less than a quarter of what we need? A third?
- We’ve opened 12 Pods and have 48 batteries. What percentage of completion have we reached?
- We have 76 batteries. How many more Pods do we need need open to reach 100?
- And so on and so on.
It was fun! Who knew Pods could be such a useful math tool?
