Decimals are a way of writing fractions using a dot (decimal point). The first digit after the point is tenths, the second is hundredths, the third is thousandths.
Your goals
- ✓You can understand tenths, hundredths, and thousandths.
- ✓You can use decimal point, hundredth correctly.
- ✓You can name each place from the decimal point outward.
Words to know
- decimal point:
- The dot separating whole-number places from fractional places.
- hundredth:
- One of 100 equal parts of one whole.
Examples
- 10.3 = three tenths = 3/10
- 20.47 = four tenths and seven hundredths = 47/100
Check these
- • Do not treat 0.5 as smaller than 0.45 because 5 has fewer digits.
- • Keep every number, symbol, label, and unit in its correct place.
- • Show enough working to check how you reached your answer.
Helpful habits
- • Read the whole question before choosing what to do.
- • Show one clear step at a time and check each step.
- • If you are stuck, draw a model, try smaller numbers, or revisit the example.
