🧱 What Is 47 Made Of? Tens and Ones

Pandi found a big pile of sticks in the garden. How many could there be? Counting one by one takes ages! Let’s learn an easy way with tens and ones.

Let’s count the sticks one by one: that makes 10! When 10 ones are tied together with a band, they make 1 ten. In Number Garden, 10 seeds also go into one packet.

How many sticks are there? First we count the tens, counting in tens: 10, 20, 30, 40. Then we add the ones: 41, 42, 43, 44, 45, 46, 47. 4 tens and 7 ones make 47!

We put numbers into the place value house. In 47, the tens place on the left has a 4 and the ones place on the right has a 7. So 47 is 4 tens and 7 ones.

The 4 in 47 is really worth 40, because it sits in the tens place. This is called the place value of the 4. The place value of the 7 is just 7. 40 + 7 = 47.

Careful! 47 and 74 are written with the same digits, but they are not the same number. 47 has 4 tens and 74 has 7 tens. When the places of the digits change, the number changes too!

Let’s jump along the number line in tens: 10, 20, 30, 40, 50, 60, 70, 80, 90, 100. Every jump is 1 ten! 47 is between 40 and 50.

What if we put 10 tens side by side? 10, 20, 30, 40, 50, 60, 70, 80, 90, 100! 10 tens = 100. We say 100 as “one hundred”.

Summary: 10 ones = 1 ten and 10 tens = 100. 47 is 4 tens and 7 ones, and the 4 is worth 40. 47 and 74 are different numbers! Now try it in Number Garden!
