Ch4 & 5 Test Review

You should be able to:

• create word problems for each type of model for multiplication and division . . . this means that you understand when they are best applied
• pictorially represent percentage problems and solve them using logic
• state whether your estimate is slightly higher or slightly lower than the actual answer without knowing the actual answer . . .this means that you are able to evaluate what you did to get your estimate
• use number sense to locate the decimal point in an addition, subtraction, multiplication or division problem answer (as opposed to the algorithm)
• when given a division problem, estimate the percent it represents
• convert very small and very large numbers into scientific notation, and use scientific notation to solve problems
• set up a problem so that it results in appropriate units (i.e. change seconds to hours or miles per hour to number of hours).
