The big idea핵심

To compare two groups, we say which one has more and which one has fewer. With numbers, we say greater than, less than or equal to.

Look at the tens first. The greater number has more tens. If the tens are the same, look at the ones.

36
29 — 36 is greater than 29

Get ready준비물

  • Tens and ones: Lego towers of 10 and single bricks, or bundles of 10 straws and single straws
  • Two plates, one for each group
  • Paper and a pencil

More and fewer

DOPut 3 tens and 6 ones on one plate. Put 2 tens and 9 ones on the other plate.
YOU“Which plate has more?”
LIAThis one.
YOU“How do you know?”
LIAIt has 3 tens. That one has 2 tens.

Greater than, less than

YOU“This plate is 36. That plate is 29.”
YOU“36 is greater than 29. Can you say it?”
LIA36 is greater than 29.
YOU“Now start with 29. 29 is …?”
LIA29 is less than 36.

The same fact can be said two ways. Practise both. Lia will hear both at school.

9 ones are still less than 1 ten

YOU“The 29 plate has 9 ones. That is a lot of ones! Is it greater?”
LIANo. 9 ones is less than 1 ten. The tens are more important.
YOU“Yes. The greater number has more tens.”

Equal to

DOMake the two plates the same: 4 tens and 1 one each.
YOU“Which is greater?”
LIAThey are the same.
YOU“Yes. 41 is equal to 41.”

    Point at the tens. “How many tens here? How many tens there? Which has more tens?”
