Lesson details

Key learning points

  1. Objects can be put into groups of 2 to make them easier to count.
  2. It is more efficient to skip count in twos instead of ones.
  3. Groups of 2 can be called twos.
  4. Counting back in twos from the amount altogether can be used to check that the count was accurate.

Keywords

  • Groups of 2 - Groups of two objects that can be counted in twos.

  • Twos - Another name for the multiples of two or even numbers.

  • Altogether - The amount in the whole set or group.

  • Accurately - An accurate result means a result that is correct.

  • Efficiently - Not wasting time or effort. An efficient strategy is one we can carry out easily.

Common misconception

Children may confuse the number of groups with the amount altogether, for example, they may count 3 groups of 2 as 3 not 6 They may also confuse the number of groups with the group size.

Draw a ring around each group of 2 whilst using the stem sentence to help describe what you are seeing as you identify each group.

Confidence in counting in twos must be developed through frequent practice across the year as it lays the foundation for multiplying by 2 in Year 2. Provide opportunities to sing songs and recall rhymes that aid this and, wherever possible, count real objects grouped in twos.
