What children learn in Level 66
- Let's go shopping! A pencil costs 35 cents and an eraser costs 25 cents. How much for both? Add: 35 plus 25 is 60 cents.
- Ava has $20 and buys a kite for $14. The change is what's left: 20 minus 14 is 6. Ava gets $6 back.
- Use cents with cents, and dollars with dollars. The ¢ sign goes after the number. The $ sign goes in front.
- Leo has 2 quarters and 1 dime. Is that enough for a 55-cent juice box? 25, 50, 60. 60 cents is more than 55, so yes!
