This time, I'm sharing my math experiences regarding planning a First Birthday party for my son. Specifically, I want to talk about the process I went through in order to make sure I had enough punch and water for everyone (capacity).
First, I had to think about how many people would be there. There were 9 adults and 1 baby.
Then, I had to estimate about how much each person would drink. I wanted to have MORE than enough, so I I purposefully estimated a little more than I really thought each person would drink. I guessed that 4 cups would be enough for everyone.
Then, I had to multiply the number of cups by the number of adults (4 x 9 = 36). So I needed at least 36 cups.
Next, I had to figure out how many cups are in a gallon. This is where I had to visualize my "King Gallon".
It helped me remember that there are 16 cups in a gallon. If I need to provide 36 cups total, I would need 3 gallons of punch or water because 16 cups x 3 gallons would give me 48 cups, with 12 extra cups in case someone was extra thirsty.
Finally, I was ready to make the punch and buy the gallons of water!
Do you have a saying or graphic that helps you remember the standard units of capacity? I'd love to hear your ideas!
