A “Trick” with Nine and Eight

A “trick” with nine

Imagine that 9 wants to be ten! It's not happy—

it wants to become a full TEN!

So, nine asks the other number (this time, 7) to

give him some in order to make himself to be a ten.

↓

Seven says, “OK,” gives one to 9, and has only

six left for himself.

= 16

In the end, we have 10 and 6. We get 16.

We can also show the same thing this way →

9 + 7

| \

Notice: it will also work if the second

9 + 1 + 6

number is 9. Why? Because you can add

10 + 6 = 16

in any order. 5 + 9 is the same as 9 + 5.

1. Circle all of the blue marbles and some of the yellow ones so that you get a ten. Add.

10 + 5

= _______

10 + _____ = _______

2. Fill in the blanks. Imagine that nine wants to become a ten.

9 + 8

9 + 7
