Comparing apples with apples 1

The Ministry is migrating nzmaths content to Tāhurangi.           
Relevant and up-to-date teaching resources are being moved to Tāhūrangi (tahurangi.education.govt.nz). 
When all identified resources have been successfully moved, this website will close. We expect this to be in June 2024. 
e-ako maths, e-ako Pāngarau, and e-ako PLD 360 will continue to be available.

Activity

Prior knowledge.

  • Work with fraction strips

Background

In different resource books working with fractions is placed at different stages. Problems with like denominators are certainly at a lot lower level than stage 8. Book 8 would suggest stage 5, but since students at that stage have just learned part whole strategies and are only dealing with small numbers for this, it seems harsh to suddenly "change the rules of addition" for them. Working on symbols like this thus seems to logically fit at stage 6.
