Comparing decimals means lining up the decimal points and comparing place by place. Each sheet has twenty pairs of decimals with a line between them, and your child writes >, < or = on the line.
Building Confidence uses tenths, On Level uses tenths and hundredths together, and Challenge Me uses numbers with different lengths and whole parts, such as 3. 07 and 3. 7.
What your child will learn
Compare decimals to the hundredths
Compare decimals with different lengths
Know that 0.5 and 0.50 are equal
Common Core standard: 4.NF.C.7
Worked example
0.45 < 0.5, because 0.5 is 0.50 and 50 hundredths is more than 45 hundredths.
Common mistake
Thinking the longer decimal is bigger, so 0.45 looks larger than 0.5.
Helpful hint
Line up the decimal points, write in any missing zeros, then compare place by place from the left.
