What children learn in Level 42
- Decimals are everywhere: prices, race times, and distances. A book costs 6 dollars and 49 cents, and a pen costs 1 dollar and 75 cents. What's the total?
- Paying with 10 dollars? Subtract to find the change.
- Tables use decimals too. Read this one to see how far each boat sailed.
- Swift sailed farthest. It went 2.75 miles farther than Reed. The numbers are small, but the thinking is the same as always.
- Try it with a grown-up. Find three prices at home or in a store, add them, and check with an estimate.
