Read and write numbers with up to 3 decimal places
Lesson details
Learning outcome
I can read and write numbers with up to 3 decimal places.
Key learning points
- There are 10 one thousandths in one hundredth.
- There are 100 one thousandths in one tenth.
- There are 1,000 one thousandths in one whole.
- Thousandths are recorded in the third decimal place so one thousandth is 0.001
Keywords
Thousandth - One thousandth is one part in one thousand equal parts.
One thousandth the size - When a whole is divided into one thousand equal parts, we can say one of those parts is one thousandth the size of the whole.
Thousandths column - The thousandths column places the number of thousandths a given number has.
Millimetre - A millimetre is a measure of length that can be abbreviated as mm.
Common misconception
Pupils record numbers like 29 thousandths incorrectly as 0.0029
Continue to link representations of thousandths to the place value chart and use language of ten thousandths being equal to one hundredth.
Teacher tip
Make sure pupils continue to develop a sense of magnitude for one thousandth in comparison to one whole, one tenth and one thousandth. Replacing place value headings for representative bars is a good way to continue to develop this.
