1. What do these signs mean? What process are you doing to know the meaning of these signs?

2. Solve. 331 students went on a field trip. Six buses were filled and 7 students traveled in cars. How many students were in each bus?

3. LT I can solve equations that are word problems

4. Steps in solving word problems Step 1 Read the problem entirely – Underline/box the question Step 2 Work in an organized manner – Figure out exactly what you need but don’t have – Name/label things Pick variables to stand for the unknowns Draw pictures, if it helps you Look for “key” words that indicate certain mathematical operations.

5. Words that indicate an Operation Addition increased by more than Combined, together Sum Added to

6. Subtraction Decreased by Minus, less Difference between/of Less than, fewer than Multiplication Of Times, multiplied by Product of

7. Division Per, a Out of Ratio of, quotient of Percent (divide by 100) Equals Is, are, was, were will be Gives, yields Sold for

8. Consecutive Numbers 1 +1 2 +1 3 +1 4 n n+1 n+2 n+3 Even Consecutive Numbers 2 +2 4 +2 6 +2 8 n n+2 n+4 n+6 Odd Consecutive Numbers 1 +2 3 +2 5 +2 7 n n+2 n+4 n+6

9. Number Word Problems Hints Represent the first number by a variable, “n” When finding the sum of consecutive even or consecutive odd integers, you are always adding by 2’s.

10. Example The sum of two consecutive numbers is 15. Find the numbers.

11. Example The sum of 3 consecutive odd numbers is 147. Find the numbers.

12. Age Word Problems When solving age problems, you need to represent the following in terms of a variable: the present ages of the people or things involved the age, at the other specified time, of the people or things involved then, form an equation based on these representations

13. Example Cary is 9 years older than Dan. In 7 years, the sum of their ages will equal 93. Find both of their ages now.

14. Example Fred is 4 times as old as his niece, Selma. Ten years from now, he will be twice as old as she will be. How old is each now?
