More Geoboard Fractions

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

Background

Unlike the Creating Farctions activity, creating unit fractions for thirds, fifths, sixths, sevenths ... on geoboards requires the students to use multiplicative thinking to define what one whole means.

For example, with fifths, only 15, 10, and five squares on the geoboard may be used to represent a whole. The diagram shows a whole with an area of 15 squares that has been divided into fifths.

Activity
