```									Learning intention: To multiply a two digit number by a one digit number. Useful when you’re working with money - and
lots of other things you do!

Example:

36 x 4 =

Partition the number to make it easier: 36 = 30 + 4. So, to work it out, calculate 30 x 4, then 6 x 4, and add the answers
together.

30 x 4 = 120    6 x 4 = 24   120 + 24 = 144. The old fashioned way is this:              36
x 4
______
120
24

144

Now use the method to work these out: remember to estimate first, so you know if                 your answer is sensible.

a) 49 x 3 =                         g) 26 x 9 =
Now make up some of your own to
do - you can use one from each of
b) 54 x 4 =                         h) 68 x 7 =                  these sets of numbers or choose
c) 57 x 5 =                         i) 41 x 9 =
39                56                98                47

22                90                44                75
d) 23 x 7 =                         j) 84 x 5 =

e) 55 x 5 =                         k) 66 x 4 =
2                 7                 9                 4

3                 8                 6                 5
f) 67 x 6 =                         l) 70 x 7 =
l) 70 x 7 =
