Parties, Balloons, and Elementary Math Skills!

Aug 10, 2018 | Tustin

Did you know that helium balloons have been used on other planets? That’s right! The Russian space probes Vega 1 and Vega 2 used helium balloons to drop scientific instruments into the atmosphere of Venus in 1985. We think of balloons as pretty party favors, but they’re actually pretty amazing things! 
This week’s word problem challenge asks you to figure out the number of party balloons Emily originally had based on how many blew away in the wind. You’ll need foundational elementary skills such as addition and subtraction to solve this one. Let’s get started! Question: Emily was bringing balloons to a party, but a gust of wind blew 11 of them away. If she has 18 balloons left, how many balloons did she start with?
