Simple Math at Home

In the previous post, we learned about Place Value. This time we’re going to learn to rename a place value.

We have learned that 1 ten equals 10.
Now, 1 ten = _______ ones.

In 10 how many ones (1 individual piece) are there?

Looking at the graphic above, breaking apart the group of 10 into individual pieces, we will have 10 individual pieces.

1 ten = 10 ones.

Let’s see now how many tens (groups of 10) are there in 1 hundred?

Breaking 1 hundred into groups of 10 or tens, we will have 10 groups of ten.

1 hundred = 10 tens.

Let’s recap:
1 ten = 10 ones.
1 hundred = 10 tens.
So, 1 hundred = 100 ones.

Let’s discover the concept further

If we have 14 ones, how can we rename this?

Let’s make a group of 10; it’s easier to count.
In 14 ones, we can make 1 group of 10 and have 4 blocks left.
Therefore, 14 ones can be renamed into 1 ten and 4 ones.

Let’s see few more examples:

Renaming does not change the amount. It simply gives us another way to name the same amount.

Once your child understands this idea, they have an important foundation for learning addition and subtraction with renaming later.

Happy teaching! I hope math feels a little simpler at home.
