Friday: Freddy's decimal game
Freddy the Frog hops onto the biggest lily pad in the pond.
"Ribbit! Today every lily pad has a decimal or a fraction on it," he says.
Lizzy the Lizard peeks at the numbers through her magnifying glass.
"I see tenths, hundredths, and even some fractions from last week," she says.
Bennie the Bear nods. "Read each number carefully. Say its places out loud."
Freddy straightens his bow tie. "Let the games begin!"

Game 4: True or false?
Write tenths as hundredths to check.
| Sentence | True or false? |
|---|---|
| 0.72 = 72/100 | ? |
| 0.06 > 0.6 | ? |
| 4 × 3/10 = 12/10 | ? |
| 2/10 + 35/100 = 0.55 | ? |
| 0.4 = 0.40 | ? |
WHY THIS EXERCISE0.06 is 6 hundredths and 0.6 is 60 hundredths, so 0.06 < 0.6.
Try it
Make 10 hops like Freddy. Each hop is 0.1 of your trip.
Stop after 7 hops. What decimal of the trip is done?
How many tenths are left?

Draw a lily pad with a decimal on it. Draw its picture on a hundred grid.
Ribbit! Tomorrow is a Number Hunt for decimals.
