Unit 5 Resources - Multiplying and Dividing Fractions
To get an overview of the skills students will learn in this unit, please read the Overview Parent Letter for Unit 5 on the Bridges in Mathematics website.
Strategies for Multiplying A Whole Number by a Fraction
Use the strategy chart below to remind your child of the various strategies that could be used to multiply a whole number by a fraction. The simplest strategy is strategy # 1 - repeated addition, as it can be used for any fraction. We will revise the chart to only incude universal strategies that can work for equations with ANY fractions.
Students have not learned how to multiply a fraction by a fraction, so I would not emphasize strategy # 5. Although it seems simple in terms of calculation, it won't make sense to student conceptually.

Math Stations - January 9th
Place Value Station
After you finish the activity at your station, watch at least the first Khan Academy video. Then try a practice activity to see how well you can solve the problems. If you have enough time remaining, watch the other videos from this list. Remember, if you can't watch them all, you can always watch them at home!

Khan Academy Links
The following Khan Academy links have been selected by us to reinforce the skills that will be learned in this unit. We encourage you to use these links to provide support with the learning of prerequisite math skills that are needed for success in this unit, as well as skills that will be taught in the unit.
- Intro To Decimals. This link leads to a series of videos including Identifying whole number and decimal place values, the relationship between fractions and decimals, expanded notation for place value, writing decimals as words, and representing decimals in a grid. Follow the link at the bottom of the Intro to Decimals series, for the next series of videos on decimals.

- Adding and subtracting decimals to the hundredths place
- Rounding decimals to the nearest one, tenth, and hundredth
- Comparing pairs of decimals to the thousandths place
- Explains patterns in the placement of zeroes when multiplying by 10 (Although this is a skill that students only need to be familiar with by the end of the unit, it will be on the test, so you might as well practice this too!)
