# Comparing Unit Parts

Thursday 12/11/08

### Do-now: Comparing with <, >, and =

If two things are not the same size, I can use < or > to indicate which is bigger. Remember that the "alligator mouth" always points toward the bigger thing.

Fill in >, <, or = between the pair of objects in the problems below to indicate whether the first object is greater than, less than, or equal to the other.

1.

2. A car              An airplane

3. 73              5.921

4.

5. A computer              A calculator

6. 6 * 7              84 / 2

### Comparing units and parts

For each of the problems below:
• Draw the two things listed.
• Write a math sentence comparing them with <, >, or =
• Write a sentence in words comparing the two, using "is smaller than", "is bigger than", or "is the same size as."
(Hint: if you break up all the units, it is easy to figure out which pieces are bigger: whichever piece is smaller, more of them will fit in.)
1. a) Two kips b) A gorf. 2. a) 1/2 blig b) 1 turp 3. a) A zib b) A half of a turp 4. a) 1/4 ulum b) 1/2 blig 5. a) A third of a turp b) A half of a kip 6. a) 1/5 ulum b) 1/2 turp ### Comparing fractions of numbers

For each of the problems below, figure out how the two things compare. If the problem is written in math, fill in <, >, or =. If the problem is written in words, fill in "smaller than", "bigger than", or "the same size as."

1. Thirty two is                      fifty six.

2. 14      3

3. A third of sixty is                      twenty.

4. 39      1/2 × 72

5. A quarter of forty is                      a third of thirty.

6. 1/2 × 24      1/6 × 72

7. A fifth of one hundred is                      one quarter of seventy two.

8. 1/3 × 36      1/4 × 56
