GRASS Method of Solving
Math Questions
G.R.A.S.S.

Given: What do you already know?

Required: What do you need to find out?

Analysis: How are you going to solve it?

What formula? What operation (+,-, x, &divide;)?

Solve: Use chosen method to solve question

Statement: A sentence that states your solution
Example:

At the market there are 600 oranges, 500
apples, 74 carrots, and 300 bananas.
How many pieces of fruit are there?

Given:
 Oranges
= 600
 Apples = 500
 Carrots = 74
 Bananas = 300

Required:
 Fruit

=?
Analysis:
 Oranges

Solve:


+ Apples + Bananas = Fruit
600
+
500 + 300
= 1400
Statement:
 There
