### The Fifties

• Counting further On The Number Strip
• Count And Write The Numbers In The Boxes
• Read And Write The Numbers In Tens And Ones

### The Sixties

• Counting further On The Number Strip
• Count And Write The Numbers In The Boxes
• Read And Write The Numbers In Tens And Ones

### The Seventies

• Counting further On The Number Strip
• Count And Write The Numbers In The Boxes
• Read And Write The Numbers In Tens And Ones

### THE EIGHTIES

• Count And Write The Numbers In The Boxes
• Read And Write The Numbers In Tens And Ones

### The Nineties

• Counting further On The Number Strip
• Counting further On The Number Strip
• Read And Write The Numbers In Tens And Ones

#### Steps

8 Ones + 5 Ones = 13 Ones.
13 Ones = 1 ten 3 Ones.

10 Ones = 1 ten
6 Tens and 3 Ones = 63.

Write 3 in the Ones column and take 1 ten to the Tens column.

1 ten + 2 Tens + 3 Tens = 6 Tens.
Write 6 Tens in the Tens column.

Write 3 in the Ones column and take 1 ten to the Tens column.

### Subtraction (Count Backwards)

• Subtract 6 from 50.

Start from 50. Count 6 spaces backwards. You will reach 44.So,

• Subtract 9 from 32
• Subtract 5 from 29

### Subtracting Tens

• Subtract 40 from 50.
If we subtract Ones, zero subtracts zero equals to zero.
So, we subtract the Tens only. Cross out the Tens and show it.
• Subtract 60 from 90.

### Subtraction With Regrouping

• Subtract 28 from 42.

Steps

• Subtract the Ones.
2 Ones < 8Ones
There is not enough Ones. So, we regroup:
4 Tens and 2 Ones = 3 Tens and 12 Ones.
12 Ones - 8 Ones = 4 Ones.
• Subtract the Tens
• Subtract 47 from 81.

### Checking Subtraction

• For checking subtraction, we add the number which is subtracted to the difference.
• Subtract 36 from 52 and check the difference.

So, after checking, we can see that the sum of difference and the number which is subtracted is equal to the number which subtracts.
