Compare: Tell what is the same and what is different Describe: Use words to create a mental picture for the reader Determine: Use math to find a solution to the problem List: Use point form Explain: Use words and symbols to make your solution clear Simplify: Put the current question into it’s most simplest form Justify: Give reasons and evidence to show that your answer is correct Show your work: Record all calculations and all the steps you went through to get your answer. You may use words, number, graphs, diagrams, symbols and/or charts **NOT FOLLOWING THESE DIRECTIONS MAY CAUSE YOU TO ANSWER A QUESTION INCORRECTLY OR MAY CAUSE YOU TO LOSE SIGNIFICANT “COMMUNICATION” MARKS. ** 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, ÷)? 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 are 1400 pieces of fruit at the market
