When multiplying by ten encourage the student to look for patterns. Notice that whenever you multiply

ten times any number the answer is that number plus a zero. That is because 10 is made up of a 1 digit and a 0

digit. So 4 times 10 is 4x1=4 and 4x0=0, or 40. To make sure the student has this concept, I like to ask, “What is

banana times ten?” The answer is banana zero pronounced “banana-ty”. The “ty” stands for ten. These are

easy facts to learn and remember, but don’t take them for granted. Make sure they are mastered using any of the

techniques shown below.

On the skip counting sheets, there have been rectangles where the student wrote in the fact at the

end of the line in the space with an underline. These can be put to the same use by adding the

multiplication problem to the multiple of 10. Here are a few examples.

“ten counted one time equals ten”

or 10x1 = 10

“ten counted two times equals twenty” or 10x2 = 20

“ten counted three times equals thirty” or 10x3 = 30

“ten counted four times equals forty”

or 10x4 = 40

10•6=60

10•5=50

10•4=40

10•3=30

10•2=20

10•1=10

Another way to show this is on a number chart. Circling all of the 10 facts, or multiples of 10, reveals

the pattern that corresponds to the blocks above.
