If using guess and check – decide if you are right

List the items

Dothe problem by guessing numbers

Define variable: make one of the items a letter. Make an equation based on patterns you see. Do

A box of fruit has three times as many nectarines as grapefruit. Together there are 36 pieces of fruit. How many pieces of each type of fruit are there?

• Number of nectarines is three times the number of grapefruit.

• Number of nectarines plusnumber of grapefruit equals 36.

Pull out the key info and understand what is being asked

• # of nectarines (3 times # of grapefruit)

• # of grapefruit

List the items

Dothe problem by guessing numbers

If using guess and check – decide if you are right

x + 3x = 36

4x = 36

x = 9 (grapefruit)

3x = 27 (nectarines).

Define variable: make one of the items a letter.

Make an equation based on patterns you see. Do: solve the equation

• 9 grapefruit

• 27 nectarines
