# 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.

` `

- A car An airplane

- 73 5.921

` `

- A computer A calculator

- 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.)- a) Two kips b) A gorf.

### 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."
