Can you work this out? 73 x 58 =

Did you get it right? 73 x 58 = x 70 3 50 3500 150 8 560 24 3650 + 584 + 584 4234

The GRID METHOD Easy as: 1 2 3 4

1, 2, 3, 4 1. Split each number into hundreds, tens, units 2. Put them in a table one number in a row, the other in a column 3. Multiply each number in the row by each number in a column 4. Add together all of the numbers obtained by multiplying

The Grid Method 25 x 35= 20 + 5 30 + 5 x 20 5 30

25 x 35= X 20 5 30 600 6 150 15 10 100 25

What next? 25 x 35 = X 20 5 30 600 150 100 25 6 1 5 +   2 8 7 5

Try this one… Use the Grid Method or any other method that works  71 x 43 =

71 x 43 = X 70 1 40 3 2800 28 40 210 21 3

71 x 43 = X 70 1 40 3 2800 28 40 2 8   1 4 + 3 5 210 21 3

Can you multiply three digit numbers? How would you set this one out? 124 x 45 =

124 x 45 = X 100 20 4 40 4000 800 160 5 500 4   8 1 6 5 + 2

Self-assessment: Can you work these out? 46 x 25 560 x 28 245 x 152 Choose a smiley face and write a comment expressing how you feel about today’s learning objective

L.O. To be able to perform Long Multiplication By the end of the lesson we will be able to: multiply a 2 digit number by a 2 digit number multiply a 3 digit number by a 2 digit number multiply a 3 digit number by a 3 digit number Date automatically changes to today’s date.
