As summer ends, let’s give a big thank-you to Harry Burt, who in 1920 figured out how to coat ice cream in hardened dark chocolate. Thanks to him, suddenly people could drive ice cream around in trucks! So our fan Lisa B. asked, how many bars and popsicles does an ice cream truck sell in 1 day? Well, at a park or beach a truck can unload 20-30 bars to one crowd. After 10 stops like that, a truck could sell 200 to 300 bars in a day. And we’re happy to stand in line for one.

*Wee ones:* Lots of ice cream bars look like rectangles. How many sides does a rectangle have? Is the floor of your room a rectangle?

*Little kids:* If a driver sells 4 ice cream sandwiches and 2 popsicles, how many ice cream treats is that? *Bonus:* If he sells an orange popsicle, then a lemon, then a cherry, then orange, lemon, cherry…what flavor is the 11^{th} popsicle?

*Big kids:* If they keep selling orange, lemon, cherry, then orange to repeat, what flavor is the 25^{th }popsicle? See if you can get it without counting up! *Bonus:* If the truck sells twice as many treats at the second stop as at the first, and sells 60 *total*, how many did it sell at each stop?

*The sky’s the limit:* If the driver buys each treat for $1, which way will make more money, selling 20 of them for $5 each or 30 of them for $4 each?

__Answers:__

*Wee ones:* 4 sides.

*Little kids:* 6 treats. *Bonus:* Lemon.

*Big kids:* Orange, since it’s the first treat in a new set of 3. *Bonus:* 20 treats, then 40 treats.

*The sky’s the limit:* Selling 30 of them for $4. In the first way, selling them for $5 will make $4 extra on each, so 20 treats make $80. Selling for $4 will make only $3 on each, but 30 of those will make $90 total.
