• Tenths and hundredths4th grade

  A hundred grid is one whole. Each column is one tenth (0.1) and each small square is one hundredth (0.01). 35 shaded squares are 0.35, or 35/100.

• Decimal place value4th and 5th grade

  Places to the right of the decimal point are tenths, then hundredths. In 4.62, the 6 is worth 6 tenths (0.6) and the 2 is worth 2 hundredths (0.02): 4.62 = 4 + 0.6 + 0.02.

How to teach decimals

1. Start with money. A dime is 0.10 of a dollar and a penny is 0.01. Children already know that 10 pennies make a dime.
2. Shade hundred grids. A column is a tenth and a square is a hundredth. Seeing 0.3 and 0.30 shade the same area settles a lot of confusion.
3. Say it properly. Read 3.45 as "three and forty-five hundredths", not "three point four five", while children are learning what it means.
4. Fill with zeros. Writing 0.5 as 0.50 makes comparing and subtracting much easier.
5. Line up the points. In adding and subtracting, the decimal points must sit in a straight column.
