Explore the numbers 6 to 10 using the parts and wholes on a number line

I can identify the whole and parts of the numbers 6 to 10 using a part-part-whole model and number line.

Lesson details

Key learning points

  1. Numbers 6 to 9 can be represented as two parts, one part of 5 and a smaller part.
  2. Part-part-whole relationships can be represented as a bar model or on a number line.
  3. A variety of representations, including a number line, can be used to explore the five and a bit structure.

Common misconception

Pupils may not connect more abstract representations of part-part-whole relationships with practical examples showing the five and a bit structure.

Take time to connect the representations pupils are familiar with e.g. show finger numeral representation alongside part-part-whole models and bar models to help pupils understand these all show the same relationship.

Keywords

  • Partition - To split a whole up into parts.

  • Whole - All of something. Complete.

  • Part - A piece or section of a whole.

  • Bar model - A pictorial representation of a problem where bars are used to represent the known and unknown quantities.

  • Number line - A line with numbers placed in their correct position.

Aligning cubes and a number line can be a powerful way of showing part-part-whole relationships using this more abstract representation. Using connected cubes emphasises the two parts of the whole and allows connects to be made between bar model and number line representations.
