Try This• What does x equal? How can you show this? What do you

have to do to each side?

Page 8: Algebra Tiles

Try This• The zero pairs cancel each other out leaving x=9. In order to

keep our equation balanced we have to make sure to do the same thing to each side.

Page 9: Algebra Tiles

Try This• When working with variables we want to “isolate the variable”

getting it on one side of the equals sign and everything else on the other.

Try This• Try modeling this,

Page 11: Algebra Tiles

Try This• Now try to isolate the variable. Remember, you want to get

the x on one side of the equation and everything else on the other side. Also, remember, whatever you do to one side of the equation you must do to the other.

Try This• Now try to isolate the variable. Remember, you want to get

the x on one side of the equation and everything else on the other side. Also, remember, whatever you do to one side of the equation you must do to the other.

Page 18: Algebra Tiles

Try This• Now isolate the variable. Remember, whatever you do to one

side of the equation you have to do to the other to keep it balanced.

Try This• Now we need to put our tiles into equal groups to determine

what x equals.
