Math Test This Wednesday

What You Need To Know:

The math test is on addition and subtraction of fractions.

-Know how to find common denominators so you can add fractions.  You can use a rectangular model, fraction bars, or skip counting (least common multiple), to find common denominators.

-Know how to subtract fractions using a number line.  Also, know how to subtract fractions using fraction bars to show regrouping.  Making the  two fractions into improper fractions would be another way.

Hints to study:
Study with a friend
Ask me for help if you have a question
Rework and review your homework problems.

Sample problems for extra practice:

John ate 1/3 of and ice cream and his friend ate 4/6.  How much did they eat in all?

On Monday Fred worked on his homework for 1 1/3 hours. Tuesday he worked 2 1/6 hours.  Jane worked on her homework for 1 5/6 hours.   How much more time did Fred spend on his homework compared to Jane?

Sally had a rope that was 10 1/5 inches long.  Fred had a rope that was 5 2/3 inches long.  How much rope do they have all together?  How much more rope does Sally have then Fred?

If they tied their rope together and the knot took up 1 1/8 inches, how long would their string be?
