K-2 Problem of the Month

I have a blueberry bush with 9 blueberries and a raspberry bush with 7 raspberries. I ate some blueberries and some raspberries. Now there are 4 blueberries and 4 raspberries on my bushes.

Did I eat more blueberries or more raspberries? How do you know?

Check your thinking by using pictures or numbers to show how many blueberries I ate and how many raspberries I ate.

3-5 Problem of the Month

Every year a carnival comes to Hallie's town. The price of tickets to ride the rides has gone up every year.
Big picture
  1. In 2008, Hallie’s allowance was $9.00 a month. How many carnival tickets could she buy with one month's allowance?
  2. If her allowance had stayed the same, $9.00 a month, how many carnival tickets could she buy in 2012?
  3. In 2012, Hallie’s allowance was $14.00 per month. How much did her monthly allowance increase between 2008 and 2012?
  4. How much more did a carnival ticket cost in 2012 than it did in 2008?
  5. Was Hallie able to buy more carnival tickets in 2008 or in 2012 with one month's allowance?
  6. What would Hallie's allowance need to be in 2012 in order for her to be able to buy as many carnival tickets as she could in 2008?
  7. What happens to your ability to buy things if prices increase and your allowance doesn’t increase?

6-8 Problem of the Month

On a recent trip to a local orchard, the Nomial family picked four different kinds of apples - Braeburn, Cortland, Fuji, and Rome. When they were done, they discovered that they had picked

  • a total of 360 apples,
  • twice as many Braeburn as Fuji,
  • twice as many Cortland as Rome,
  • 50% more Fuji than Rome.
How many of each kind of apple did they pick?

Extra: The Factore family went to the same orchard and picked the same four kinds of apples. When they finished, they found that

  • they had picked four times as many Fuji as Rome,
  • they had 25% more Braeburn than Fuji,
  • the number of Cortland exactly equaled the difference between the numbers of Fuji and Rome.
What fraction of their total apples are Fuji?
