Today’s lesson... What: Comparing And ORDERING RATIONAL NUMBERS Why: To compare and order groups of fractions, decimals, percentages.
3
Comparing and Ordering Fractions, Decimals, and %’s STRATEGY #1: Convert everything into ____________ first! STRATEGY #2: Start with the __________ #’s, move onto the tenths, etc. decimals whole
4
When comparing decimal #’s... Start with the __________________________ place value digit and compare. If there is a “tie,” move on to the next digit, etc. In other words... 1) Compare the whole numbers. 2)If there is a “tie,” move on to the ______________________________. 3)If there is another “tie,” move on to the _______________________________. 4)If needed, keep moving on to the next place value digit(s). greatest tenths hundredths

Remember: CONVERT TO DECIMALS FIRST!!!! Guided practice: Place a greater-than (>), less-than (<), or equal (=) sign in the blanks: 1)0.023 _____ 0.6 2) 35% _____ 3.5 3) 2 / 5 _____ 40% <<= Comparing Fractions, Decimals, and %’s Your turn: Place a greater-than (>), less-than (<), or equal (=) sign in the blanks: 4) 4.5 _____ 45% 5) 1.5% _____ 0.0092 6) 3 / 8 _____ 0.4 > > <
