Multiplication Tricks
ZERO
When you multiply by zero,
the product is ALWAYS 0!
0x4=0
DOUBLE IT
When you multiply by two,
double the other number.
2 x 4 = 8 because 4 + 4 = 8
SAME NUMBER
When you multiply by one,
the product is ALWAYS
the same number! 1 x 9 = 9
THREE TIMES
Remember the “Three Times” song:
3,6,9,12,15,18,21,24,27,30
3 x 7 = 21
CLOCK
5 x 3 = 15
Think of the minute
hand on the clock and
Double the double.
how we count by 5s.
4 x 6 = 24 because12 + 12 = 24
When the minute hand is on the 3, it is :15
DOUBLE DOUBLE
RIDDLES
6 x 6 lollipop licks, 6 x 6 is 36
6 x 7 at the zoo, 6 x 7 is 42
6 x 8 is really great, 6 x 8 is 48
FOOTBALL
San Francisco 49ers
got a touchdown, 7 points.
7 x 7 = 49
PATTERN
(think 5,6,7,8)
56 = 7 x 8
RHYME
8 times 8 went to the store,
to buy Nintendo 64
8 x 8 = 64
FINGER TRICK
9 x 8 = 72
The product
will begin
with one
digit less
than the
multiplier.
8 -1 = 7
The product,
when multiplied
by 1-10, will
always add to 9.
ones + tens = 9
7+2=9
