 Build and name numbers (to 500)

Lesson

We can use blocks to make numbers. When we're using blocks we need to think about how many numbers are in each block.

We can start with one block which represents $1$1 unit.
If we put $10$10 unit blocks together we get $10$10 units.
If we put ten $10$10 unit blocks together we get $100$100 units!

$1$1 $10$10 $100$100   We can use blocks to make whole numbers. If we want to make the number $7$7 we can use $7$7 unit blocks. $+$+ $+$+ $+$+ $+$+ $+$+ $+$+ $=7$=7

Let's use the blocks to make the number $117$117

How many hundreds, tens and units (ones) are there in the number $117$117?

$117$117         Examples
