How do you write a fraction as a decimal in 4th grade?

If the bottom number is 10, write the top number one place after the point (3/10 = 0.3). If it is 100, use two places (3/100 = 0.03). A fraction like 4/5 is first rewritten with 10 on the bottom (8/10), then written as 0.8.

What is the difference between 0.3 and 0.03?

0.3 is 3 tenths and 0.03 is 3 hundredths, so 0.3 is ten times as much. Shading both on a 100-square grid (30 squares and 3 squares) is the quickest way to see it.

Which standard do these worksheets support?

They support CCSS 4.NF.C.6, using decimal notation for fractions with denominators 10 or 100, and lead into 4.NF.C.7, comparing decimals to hundredths.

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.
