In this activity, we will be adding coins.
We will be adding 10ps and 1ps.
We can think about place value to help us work these out.
Let's add up these coins together:
In the tens column, we count the coins in 10s. There are 4 of these coins so we need to count in 10s 4 times:
10, 20, 30, 40
So, we have 40p in the tens column.
Now, let's count the ones column. There are 7 of these coins so we need to count in 1s 7 times:
1, 2, 3, 4, 5, 6, 7
So, we have 7p in the ones column.
Now we can just put the tens and ones together: 40 + 7 = 47p
Can you add the coins together to work out the missing number in the calculation below? Write the number in the box below.
What is missing in this number sentence?
We have the total as that number is after the equals sign.
We have the tens as these are the numbers that end in zero, there are two 10s so that makes 20.
This means we are missing the pennies. Count how many 1ps there are and that is the missing number.
There is 1p.
Are you happy with that?
Then let's get started!
