Presentation Transcript
draw a picture
DRAW A PICTURE
  • When problems involve objects, distances, or places you can draw a picture to make the problem easier to understand.
  • You will often use your picture to solve the problem.
use concrete models
USE CONCRETE MODELS
  • If a problem involves objects, you can sometimes make a model using (or drawing) those objects to act out the problem.
guess and check
GUESS AND CHECK
  • If you do not know how to solve a problem, you can always make a guess.
  • Then check your guess using the information in the problem.
  • Use the result to make a better guess.
  • Repeat until you find the correct answer.
work backwards
WORK BACKWARDS
  • Some problems give you a sequence of information and ask you to find something that happened at the beginning.
  • To solve a problem like this, you may want to start at the end of the problem and work backwards.
find a pattern
FIND A PATTERN
  • In some problems, there is a relationship between different pieces of information.
  • Examine this relationship and try to find a pattern.
  • You can then use this patter to find more information and the solution to the problem.
make a table
MAKE A TABLE
  • When you are given a lot of information in a problem, it may be helpful to organize that information.
  • One way to organize information is to make a table.
solve a simpler problem
SOLVE A SIMPLER PROBLEM
  • Sometimes a problem contains large numbers or requires many steps.
  • Try to solve a simpler problem that is similar.
  • Solve the simpler problem first, and then try the same steps to solve the original problem.
determine a reasonable answer
DETERMINE A REASONABLE ANSWER
  • In some problems, it is possible to find the correct answer by determining which answers could make sense in the situation.
  • Estimate or use mental math skills to determine a reasonable answer.
act it out
ACT IT OUT
  • Some problems involve actions or processes.
  • To solve these problems, you can act it out.
  • Actively modeling the problem can help you find the solution.
make an organized list
MAKE AN ORGANIZED LIST
  • In some problems, you will need to find how many different ways something can happen.
  • It is often helpful to make an organized list.
  • This will help you count the outcomes and be sure that you have included all of them.
