Comparing Fractions

100

2/5  ___  3/6

Less than

2/5 is less than a half, 3/6 is equal to a half

200

1/5  ___  1/8

Greater than.

Fifth are bigger than eighths because you only cut the cake into five pieces vs. cutting the cake into eight pieces.

300

2/7  ____  6/7

Less than.

The wholes have the same number of pieces, so they are the same size. Two of them is less than six of them.

400

5/6  ___  6/7

Less than.

They are both missing one piece. 6/7 is missing a smaller piece, so there's more of it.

500

5/8  ___  3/7

Name 3 different ways  5/6 can be decomposed (broken apart)

2/6 + 2/6 + 1/6

1/6 + 4/6

3/6 + 2/6

200

4/6 + 3/6 =

4/6 + 3/6 =  7/6 OR 1 1/6

300

5/9 + 5 8/9 =  

5/9 + 5 8/9 =  5 13/9... 6 4/9

400

3 1/4 + 4 2/4 =

3 1/4 + 4 2/4 =  7 3/4

500

5 4/8 + 3 7/8 =

5 4/8 + 3 7/8 =  8 11/8...  9 3/8

Subtracting Fractions

100

7/8 - 2/8 =

7/8 - 2/8 =  5/8

200

1 2/4 - 3/4 =

You can use a number line or "standard algorithm"

1 2/4 (OR 6/4) - 3/4 =  3/4

300

4 2/9 - 2 4/9 =

You can use a number line or "standard algorithm"

4 2/9 (OR 3 11/9) - 2 4/9 = 1  7/9

400

6 2/5 - 2 4/5 =

You can use a number line or "standard algorithm"

6 2/5 (OR 5 7/5) - 2 4/5 =  3  3/5

500

5 1/3 - 3 2/3 =

You can use a number line or "standard algorithm"

5 1/3 (OR 4 4/3) - 3 2/3 = 1  2/3
