The Nine Pattern

Our world is made up of patterns. From the way deer antlers grow, to petals on a flower, patterns are everywhere for us to observe.

Multiplication and division using 9 also show many patterns. Look carefully at the x9 facts. What patterns do you see?

After you have found several patterns, click on the pattern button to see some of the patterns I found. Each click shows a different pattern.

9 x 1 = 9
9 x 2 = 18
9 x 3 = 27
9 x 4 = 36
9 x 5 = 45
9 x 6 = 54
9 x 7 = 63
9 x 8 = 72
9 x 9 = 81
9 x10 = 90

Using some of the patterns we found, fill in the blanks by typing the correct numerals.
The box will stay empty until the correct answer is entered.
Press Tab to move from box to box.

9 x 3 =	so	/ 3 = 9
9 x 5 =	so	/ 9 = 5
9 x 8 =	so	/ 8 = 9
9 x 4 =	so	/ 4 = 9
9 x 9 =	so	/ 9 = 9
9 x 6 =	so	/ 6 = 9

You’re doing great! Don’t let these trick you. Use the patterns we found to help you fill in these blanks.

The box will stay empty until the correct answer is entered.
Press Tab to move from box to box.

27 / 9 =		36 / 9 =
45 / 9 =		18 / 9 =
63 / 9 =		72 / 9 =
54 / 9 =		81 / 9 =

You’re on a roll!

Now try the multiplication wheel.

Type the correct answer in the box for
each x9 fact.

After you practice the nines, change the numeral in the middle and practice other multiplication facts.
