I was at Walgreens last night to buy my sick teenager some Gatorade when I was faced with the following scenario, so I decided to put it into a task for review of division of decimals. I also thought it might be a good primer for the measurement chapter they are on. Standard 5.NBT.B.7. Here is the Nearpod Link.
Estimate how much each bottle cost per ounce. Give a too high estimate for each and a too low estimate for each.
What information do you know? What information do you need?
How much does Cool Blue cost per ounce? How much does the Orange cost per ounce if you buy two? If you buy only one?
What’s the math?
Please leave me feedback on how I could make this task better. It’s my first one!
Would it be better to start with a video of me opening a wallet with $5 in it and reveal with a video of me checking out and the change I get back from the cashier? Come to think of it, that would be a great 3 act on percentages (for tax).
