Lesson details

Key learning points

  1. 10 is ten times the size of 1
  2. A digit in the tens column is 10 times the value of a digit in the ones column
  3. Multiples of 10 have a zero in the ones column

Common misconception

Pupils may start talking of 'adding a zero' to multiply by 10

Don't dismiss this as it is disguising an understanding of a pattern but reassure the pupils that this will be explained later through place value discussions in the coming lessons.

Keywords

  • Multiple - A multiple is the result of multiplying a number by another whole number.

  • Digit - A digit is one of the symbols of a number system. In our number system we use the digits 0, 1, 2, 3, 4, 5, 6, 7, 8 and 9

Use countable objects here. Physical resources support this learning really well to begin with.
