• djunk, It would be nice if everyone did have a clear understanding of each problem. However, some students really struggle to have that understanding. In these cases, instead of not trying, or writing 'I don't know', or leaving an answer blank; it's my opinion that it is better to try 'an' approach, rather than 'no' approach. I appreciate your input.

• Just really bad advice to teach clue wirds and to just choose numbers. Developing good problem solving skills involves solving the problem by understanding the situation as a whole. When students have a good understanding, they do not need clue words (which can be misleading anyway), nor do they need to guess which numbers to use. Using the strategies described in the power point will not provided the opportunity for students to become good competent problem solvers!

### How To Solve A Math Problem!-new and improved

1. 1. How to solve a math problem!
2. 2. Step One <ul><li>Read </li></ul><ul><li>the </li></ul><ul><li>problem </li></ul>
3. 3. Step Two <ul><li>Find out, </li></ul><ul><li>What am I supposed to find out? </li></ul>
4. 4. <ul><li>IF it’s too </li></ul><ul><li>complicated to understand the 1 st time… </li></ul>
5. 5. <ul><li>Read the problem again and AGAIN! </li></ul>
6. 6. Look for clue words Step Three
7. 7. To show you… <ul><li>which operation to use </li></ul>
8. 8. Addition <ul><li>and…add… </li></ul><ul><li>addend …plus… </li></ul><ul><li>sum …more… </li></ul><ul><li>more than… </li></ul><ul><li>in all…total… </li></ul><ul><li>all together… </li></ul><ul><li>perimeter… </li></ul><ul><li>combined </li></ul>
9. 9. Subtraction <ul><li>Minuend…subtrahend </li></ul><ul><li>difference…subtract </li></ul><ul><li>minus…take away… </li></ul><ul><li>less than…remain… </li></ul><ul><li>are left…have left </li></ul><ul><li>how much more </li></ul><ul><li>fewer…are not… </li></ul><ul><li>decreased by… </li></ul><ul><li>how much change (money) is left </li></ul>
10. 10. Multiplication <ul><li>factor…product… times…of… </li></ul><ul><li>multiplied by… </li></ul><ul><li>area…volume… </li></ul><ul><li>each…twice=2x…thrice=3x… …how many times more… </li></ul>
11. 11. Division <ul><li>dividend…divisor </li></ul><ul><li>… quotient… </li></ul><ul><li>divided by…per… </li></ul><ul><li>half = ÷ 2… </li></ul><ul><li>separated…rate… </li></ul><ul><li>ratio…fraction… </li></ul><ul><li>decimal…part… </li></ul><ul><li>percent… </li></ul>
12. 12. Beware… <ul><li>Of red herrings! </li></ul><ul><li>(false clues) In this case, numbers that are just there to trick you, but are not needed to solve the problem. </li></ul>
13. 13. What to do… <ul><li>if you’ve read the question more than once, and you still don’t know which way to turn.. </li></ul>
14. 14. Then just do something! <ul><li>You know there are four operations and you’ll have to do at least one of them. So pick one. </li></ul><ul><li>You know you need to do that operation using at least two numbers, so pick two of the numbers in the problem . </li></ul><ul><li>Then either add ‘em, subtract ‘em, multiply ‘em, or divide ‘em. </li></ul><ul><li>You may be wrong, but YOU MAY BE RIGHT! </li></ul>
15. 15. Step Four <ul><li>Solve the problem </li></ul>
16. 16. Step Five <ul><li>Now think… </li></ul><ul><li>Does this answer make sense? </li></ul><ul><li>Would I expect this to be the answer? </li></ul>
17. 17. Step Six <ul><li>Ask yourself… </li></ul><ul><li>Are there more parts to this question? </li></ul><ul><li>(Some questions have two or more parts!) </li></ul>
18. 18. Remember <ul><li>If you ONLY answer </li></ul><ul><li>half the question , </li></ul><ul><li>EVEN if you get that half </li></ul><ul><li>100% right… </li></ul><ul><li>That’s only 50% of the question... </li></ul><ul><li>And 50% is an F! </li></ul>
19. 19. Step Seven <ul><li>Check your work… </li></ul><ul><li>just work backwards, using the opposite operations and see if you end up where you began. </li></ul>
20. 20. Congratulations! <ul><li>That’s how to solve a math problem. </li></ul><ul><li>Some more clues for math sleuths… </li></ul><ul><li>Always try something. </li></ul><ul><li>Never try nothing. </li></ul><ul><li>Show your work and hand it in. Even if you don’t make it the whole way, you may have come close. </li></ul>
21. 21. Notes for teachers on texts correlation: <ul><li>Coordinates with Glencoe Mathematics (Florida Edition) texts: </li></ul><ul><li>Mathematics: Applications and Concepts Course 1: (red book) </li></ul><ul><li>Chapter 1 Lesson 1 A Plan for Problem Solving </li></ul><ul><li>Mathematics: Applications and Concepts Course 2: (blue book) </li></ul><ul><li>Chapter 1 Lesson 1: A Plan for Problem Solving </li></ul><ul><li>Pre-Algebra: (green book) </li></ul><ul><li>Chapter 1 Lesson 1: Using a Problem Solving Plan </li></ul><ul><li>The language these texts use is a little different. </li></ul><ul><li>They follow a 4 step plan </li></ul><ul><li>Explore 2. Plan 3. Solve 4. Examine </li></ul><ul><li>For more information on my math class see www.walsh.edublogs.org </li></ul>
22. 22. Notes for teachers on design. <ul><li>This slide presentation was created using Microsoft Office PowerPoint 2003 part of Microsoft Office Standard Version for Students and Teachers </li></ul><ul><li>Clip Art came from Microsoft Office PowerPoint 2003 without exception. </li></ul><ul><li>Original font used was Ghostwriter. It provided a “clue-solve a mystery” aura which I haven’t been able to get SlideShare to retain in the transformation. You can download this font for FREE (PC or Mac) at this web address: </li></ul><ul><li>http://simplythebest.net/fonts/fonts/ghostwriter.html </li></ul><ul><li>Finally, thank you.
