Creating 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.

Description of Mathematics

Number Framework Stages 5 - 7.

Required Resource Materials
Geoboards

Rubber Bands

Fractions on Geoboards (Material Master 4-20)

Activity

Activity

Get the students to fold a piece of paper a number of times and name the unit fractions created after each fold: halves, quarters, and eighths.

Activity

Get the students to create halves, quarters, and eighths on a geoboard in as many different ways as they can. For example, all of these geoboards show halves:

createfractions.

All of these geoboards show quarters:

createfractions2.

Once they have created the fractions on geoboards, the students can record them on geoboard sheets.

Extension Activity

Draw different-sized geoboards using dots on squared paper and show fractions on them. For example, draw an 8 x 3 dotted geoboard and show sixths on it.
