Multiplying a 2 digit number by a 1 digit number Using the grid method

First, split the 2 digit number into tens and units For example; 42 is split up as 4O and 2 89 is split up as 80 and 9 56 is split up as 50 and 6

Then put the tens and units into the top part of the grid and the number that you are multiplying by down the side of the grid. For example: 42 x 7: x402 7 Then multiply the tens (40) by the number on the side (7): x And then multiply the units (2) by the number on the side (7): x Finally, add the 2 answers (280 and 14) together: 42 x 7 = = 294
