Steps for Solving Math Problems Integrated Science Glencoe Chapter 3 Calculations

Step #1 – Draw a picture • It is said “A picture is worth 1000 words” • In Mr. Neely’s science class it is worth 1 point out of 6. • Stick figures are okay, but it must represent the situation.

Step #2 – Write a variable list • A variable list does just that, it lists variables. • It lists the given and unknown variables that are in the problem to be solved. V=? unknown D = 5. 0 m given T = 2. 5 s given

Step #3 – Write the equation to be used to solve the problem. • What equation will you use? • If you write it out, you will not forget later, and I can see your logic. • Write it out with no numbers, only the variables so you can be sure to use the right numbers in the correct places.

Step #4 - Show your work. • Plug in the variables you do know into the equation you just wrote down. • Leave the unknown value as the variable letter, and then solve for the unknown. V = 5. 0 m 2. 5 s

Step #5 – Calculate the correct answer • Use a calculator to compute the correct answer. • Add, subtract, multiply, divide • Use correct math operations to compute the correct answer.

Step #6 – Correct units / labels on all numbers. • Numbers without units are meaningless in science. • For example: “Give me 20!” Twenty what? • There must be correct units for each number so we know what the values represent.

Summary • Math problems are generally worth 6 points each in Mr. Neely’s class. • One point per step. • The answer by itself is worth zero points. • You MUST show me how you got the answer to earn points. • Even if you do not know how to do the problem, at least draw a picture, and write the variable list. That will earn you partial credit.
