Friday: Freddy's measuring game
Freddy the Frog hops onto a lily pad with a tape measure around his neck.
"Ribbit! Welcome to the measuring pond," he says, straightening his bow tie.
"Each lily pad has a puzzle about units, area, line plots or fractions."
Hazel the Hedgehog sharpens her pencil. Bennie the Bear unrolls a big sheet of paper.
"Remember to change to the same unit first," says Bennie.
Freddy grins. "And remember that frogs measure jumps in centimeters!"

Game 4: True or false?
Check each fact one step at a time.
| Sentence | True or false? |
|---|---|
| 6 × 12 = 72 | ? |
| 2 × 9 + 2 × 7 = 63 | ? |
| 5/10 + 30/100 = 80/100 | ? |
| 1 yard = 3 feet | ? |
| 1 liter = 100 milliliters | ? |
WHY THIS EXERCISE2 × 9 + 2 × 7 is 32, the perimeter. 63 is the area. And 1 liter is 1,000 milliliters.
