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.

Tere takes 6 hours to paint a fence. Ihaka takes 3 hours to paint the same fence.
How long does it take them to paint the fence together?
Solution:
Find how much of the fence each person can paint in 1 hour.
Tere can paint 1/6 of the fence per hour.
Ihaka can paint 1/3 of the fence per hour.
Together, they can paint 1/3 + 1/6 = 3/6 (or 1/2) of the fence in 1 hour. Therefore it will take them 2 hours to paint the whole fence.
