How many centimeters are in a meter?

100 centimeters make 1 meter and 10 millimeters make 1 centimeter. To change meters to centimeters, multiply by 100: 6 m is 600 cm.

How can I practice this at home?

Measure small objects with a centimeter ruler and say the length as a decimal, like 7.5 cm. Then measure the same object in millimeters (75 mm) to see the two names for one length.

Which standards do these worksheets support?

The conversion page supports CCSS 4.MD.A.1 (relative sizes of measurement units) and the ruler page supports 4.MD.A.2 (measurement problems with decimals).

What decimal skills do 4th graders learn?

4th graders learn decimals as another way to write tenths and hundredths (CCSS 4.NF.C.6). They write fractions like 7/10 and 37/100 as 0.7 and 0.37, place decimals on number lines and grids, and compare two decimals to hundredths using >, < and = (4.NF.C.7). Money and metric lengths give the decimals everyday meaning.

How do you compare decimals in 4th grade?

Line up the decimal points and compare place by place from the left: ones, then tenths, then hundredths. Writing 0.5 as 0.50 makes it easy to see that 0.5 is greater than 0.47.

Do 4th graders add decimals?

Yes, in a limited way. They add tenths and hundredths by writing tenths as hundredths (3/10 + 4/100 = 34/100), which is 4.NF.C.5. Adding and subtracting decimals with the standard method is a 5th grade skill.

Is there an answer key for each worksheet?

Yes. Every one of the 30 new decimals sheets has an answer key, and the two page sheets have a two page key.
