Contents Keep a word problem notebook. You can look back at strategies youve used for other problems to help you solve new ones. Word Problems: Problem Solved! Tips for Solving Word Problems Word problems might be part of your homework, on a test, or in your life. These tips can help you solve them, no matter where they show up. Be positive! When you get a problem right the first time, thats great! When you dont get a problem right the first time, dont worry.

If you dont understand todays problem, tomorrows problem will be even harder to understand. Practice! The more you practice anything, the better you become at it. Do your homework problems as thats your practice for solving word problems. Move on! If you get stuck, move on to the next problem. If you work on the ones you know how to solve first, youll feel more confident. Ask questions! When someone is helping you, asking good questions tells the person what you dont understand. Ask questions! When someone is helping you, asking good questions tells the person what you dont understand.

If you dont ask questions, you will never get answers! Take a breather! If you have tried everything you can think and are getting frustrated, take a break. Take a deep breath.

They can be solved by following four easy steps, though. The greatest speed of the fastest steel roller coaster is 134 mph (216 km/h). The greatest speed of the fastest steel roller coaster is 134 mph (216 km/h).

The greatest speed of the fastest wooden roller coaster is 78 mph (126 km/h). How much faster is the steel roller coasters greatest speed? Step 1 Read and understand the problem. Read the problem carefully. Ask yourself questions, such as: Modern steel roller coasters like this one move pretty fast. They are made to give riders the biggest thrills their dollars can buy! What do you know? The greatest speed of the fastest steel roller coaster is 134 mph. The greatest speed of the fastest wooden roller coaster is 78 mph.

What are you trying to find? How much faster the steel roller coaster is than the wooden roller coaster. What kind of problem is this? You want to know the difference between the two greatest speeds. Problems that find a difference are subtraction problems. Step 2 Make a plan. Some problems tell you how they should be solved. They may say draw a picture or write an equation.

For other problems, you will need to make your own plan. Most problems can be solved in more than one way. Some plans you might try are:

How can you solve this problem? Lets write an equation. Thats our plan. Next page
