About Introduction to Decimals

What this skill is

An introduction to decimals grounds decimal numbers in visual models: a flat grid represents one whole, a column represents one tenth (0.1), and a single square represents one hundredth (0.01).

When children learn it

Introduced in 4th grade under Common Core standards (CCSS 4.NF.C.6) to bridge fraction knowledge to decimal notation.

Teaching Tips

  • Use 100-grid graph paper: have your child color one whole column blue (1/10 or 0.1) and one tiny single square red (1/100 or 0.01). Comparing the column to the tiny square visually proves that tenths are ten times bigger than hundredths.

Common Mistakes

  • Shading entire columns when meaning hundredths.
  • Not seeing that 10 hundredths make 1 tenth.
  • Thinking 0.1 is smaller than 0.01.
