How to Read and Write Decimals
Tenths and hundredths shown on grids and in a place value chart with the matching fractions, 7/10 = 0.7 and 23/100 = 0.23, and why 0.05 needs a zero.
Shade the Decimal
Tenths strips and 10 × 10 hundredths grids to shade, with the fraction or decimal to finish. More also shows shaded grids to name both ways.
Fractions and Decimals
Changing fractions like 7/10 and 23/100 to decimals and back. More adds mixed numbers like 3 45/100 = 3.45.
Tenths to Hundredths
Problems like 6/10 = 60/100 = 0.60 on graph paper. Fewer shows tenths and hundredths grids, and Standard and More also go from hundredths back to tenths.

How to Add Tenths and Hundredths
3/10 + 4/100 worked out with hundredths grids and on graph paper, and why 3/10 + 4/100 is not 7/110.
Add Tenths and Hundredths
Problems like 3/10 + 4/100 on graph paper, with a box to change the tenths first. Standard and More mix up the order and use bigger hundredths.
Decimals on a Number Line
Number lines from 0 to 1 in tenths and between two tenths in hundredths. More adds number lines from 1 to 2.

How to Compare Decimals
Why 0.5 is more than 0.45, shown with hundredths grids and a place value chart, and putting 0.6, 0.06 and 0.16 in order.
Compare and Order Decimals
Pairs of decimals that look tricky, like 0.7 and 0.07, to compare with <, > or =. More adds sets of four decimals to order.
Money as Decimals
Bills and coins to count and write as amounts like $3.45 and as 345 hundredths of a dollar. More includes five-dollar bills.

What it is
Decimals are another way to write tenths and hundredths. 7/10 is 0.7 and 23/100 is 0.23. Fourth graders shade tenths and hundredths grids, change tenths to hundredths (6/10 = 60/100), add fractions like 3/10 + 4/100, place decimals on number lines, and compare decimals like 0.5 and 0.45. Money is a great example: $3.45 is 3 dollars and 45 hundredths of a dollar.
What comes next
Converting units, where decimals and fractions help measure.
How to teach it
- Use a 10 × 10 grid. One column is a tenth and one square is a hundredth.
- Read decimals like fractions. Say "twenty-three hundredths," not "point two three."
- Show that 0.5 and 0.50 are the same by shading 5 columns and 50 squares.
- Change tenths to hundredths before adding, just like making equal fractions.
- Practice with money, since dimes are tenths of a dollar and pennies are hundredths.
Common mistakes
- Thinking a longer decimal is bigger, like 0.45 > 0.5.
- Writing 5 hundredths as 0.5 instead of 0.05.
- Adding tenths and hundredths without changing them first, like 3/10 + 4/100 = 7/110.
- Lining up decimals by the last digit instead of the decimal point.
