ORDERING NUMBERS REVIEW

•How do we compare decimals?

•Order from least to greatest:0.6, 0.57, 0.62, 0.518

•Line up the decimal points vertically and compare from left to right.

•0.60.570.620.518

•0.518, 0.57, 0.6, 0.62

•How do we compare fractions?

•1) Use the LCM of the denominators to find a common denominator.

•2) Make all fractions have the common denominator by multiplying the numerator AND denominator by the same number.

•3) Compare numerators.

Direct Station• We will do problems that require us to order both positive

and negative numbers.

Collaborative Station• For each round, you and your partner will have a different

fraction.• Compare your fractions and find the LCM.• Each partner converts their fraction into its equivalent

form with the new denominator.• Both partners then write down the comparison (>, <, or =)

on their paper.

Collaborative Station Example• For round 1, Partner A has , partner B has • Partner A and B find the LCM of 4 and 6 is 12.• Partner A calculates • Partner B calculates • Both partners write down
