The multiples of 100
Understand that the multiples of 100 (100–900) each represent a number of hundreds with 0 tens and 0 ones
What a learner can do afterwards
- Identify that 300 means 3 hundreds, 0 tens, 0 ones
- Place multiples of 100 on a number line to 1000
- Read and write multiples of 100 and explain their place-value structure
The lesson
You already know that a hundred is ten tens. Now let's count by hundreds. Numbers like 100, 200, 300, and so on are called multiples of 100. Each one is some number of hundreds, with 0 tens and 0 ones left over.
Mia packs marbles into bags of 100. She fills 4 bags and has none left outside. She has 400 marbles: 4 hundreds, 0 tens, 0 ones.
Look at the last two digits of the number. A multiple of 100 always ends in two zeros, and those zeros are your clue: 0 tens, 0 ones.
A multiple of 100 is some number of hundreds with 0 tens and 0 ones, and it always ends in two zeros.
