Friday: Freddy's place value game

Freddy the Frog hops onto a lily pad with a big grin.

"Ribbit! Welcome to the Place Value Pond," he says.

"Each lily pad holds one digit."

"Hop to a pad, and tell me what its digit is worth."

Bennie sets a basket of stones on the bank to keep score.

"Remember," he says, "each place is worth ten times the place to its right."

Ferris takes a deep breath and gets ready for the first hop.

Round 5,280 to the nearest thousand.
Round 47,815 to the nearest ten thousand.
Round 649,999 to the nearest hundred thousand.
Round 3,950 to the nearest hundred.
SentenceTrue or false?
10 × 80,000 = 800,000?
512,040 > 512,400?
500,000 + 6,000 + 30 + 2 = 506,032?
5,280 rounded to the nearest thousand is 5,000.?
WHY THIS EXERCISE512,040 has 0 hundreds and 512,400 has 4, so 512,040 is less.
Try it
Hop like Freddy three times while you count by thousands.
Say 1,000, then 2,000, then 3,000.
Now count by ten thousands for three more hops.
◇ PLACE VALUE CHALLENGE
Each of you writes a five-digit number in secret.
Take turns giving clues, like "my ten thousands digit is 4."
Guess each other's number from the clues.
Then compare the two numbers with > or <.

Ribbit! Great game. Tomorrow is a Number Hunt.
