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:(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
