Lesson details
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.
