Describe and represent tenths as a decimal number
Lesson details
Learning outcome
I can describe and represent tenths as a decimal number.
Key learning points
- If a digit is moved one place value column to the right it becomes one tenth the size.
- One tenth is one tenth the size of one whole.
- Tenths are recorded in the column to the right of the decimal point so one tenth is 0.1
- The decimal point separates whole numbers from numbers with a decimal fraction part.
Keywords
One tenth the size - When a whole is divided into ten equal parts, we can say one of those parts is one tenth the size of the whole.
Tenths column - The tenths column places the number of tenths a given number has.
Decimal point - A decimal point is a small dot used in a number to separate the whole number from the fractional part.
Common misconception
Pupils put a digit in the ones column instead of the tenths column to represent a number of tenths.
Continue to ask what each digit that has been recorded represents, linking back to the place value chart and the role of the decimal point.
Teacher tip
Encourage children to notice that when the place value headings are removed, using zeros is not enough as each 1 is worth ten times more than it should be. This is why we need the decimal point.
