**Place Value (within 100)**

Use the random number picker link below to read 2-digit numbers (set the min number to 10 and the max number to 99). Remember 2-digit numbers have TENS and ONES!

**Representing 2-digit numbers**

All 2-digit numbers have TENS and ONES. Each digit has a value. Look at the number 37 in the Part-Whole Model below. The number has been partitioned into tens and ones. The 3 has the value 30 because it is 3 tens, the 7 has the value 7 because it is 7 ones.

If you wrote this as a number sentence it would look like this: 30+7=37. The switcher would look like this: 7+30=37.

**Activity**

Use the random number picker above to generate a number. Write the number, read the number, partition the number into tens and ones using a Part Whole Model, write the number sentence and the switcher, if you have some Lego make your own sets of dienes and make the number. Look at the example below to see what your learning may look like.
