1. Long Multiplication ++ + + - - ÷ ÷ + ÷ ÷ + Using the ‘Grid Method’

2. 14 x 5 How do we go about working out this sum? How good is your 14 times table? There is an easy way...

3. Easy as: 1 2 3

4. Step 1: 14 x 5 Split each double digit number into TENS and UNITS 104+14 = Tens Units

5. Place these at the top of your Grid Place the left over number down the side 5

6. Step 2: Multiply each number in the row by each number in a column: 5 x 105 x 4 5020

7. 5020 Step 3: Add the two numbers together: 50 +20 70

8. Therefore: 14 x 5 = 70
