Who's Better at Speed Ball?

The photo shows the latest best times for each block in speed ball.

F and B are Math 6+ and E, A, and C are Math 6.  All of the Math 6 classes are faster than the Math 6+ classes!  But does this mean that Math 6 is better at speed ball?  Can you tell which class is actually the best?

Here are the number of students in each class:

F: 24 students

B: 24 students

E: 19 students

A: 19 students

C: 19 students

Use unit rates to prove which class is actually the best at speed ball.

Ratios and Fractions Oh My!!

A very inquisitive math student said,

"All fractions are ratios, but not all ratios are fractions."

Do you agree or disagree?  Explain why using models or examples.

Super Gummy Bears!!

VAT19 has Super Gummy Bears for $30 (each Super Bear is equivalent to 1,400 Mini Bears).

The candy warehouse has 5 lb bags of mini gummy bears for $19.50. There are 145 mini gummi bears per pound (yep- that’s a unit rate!).

Which shop has the better deal if you want to get the most gummy bear for your money?

Challenge: After you figure out which shop is cheaper... How much will it cost to buy the same amount of gummy bear at the more expensive shop?
