Information transfer
You could read a report about the weather conditions around the country, and the students could draw the appropriate weather symbols onto a map of New Zealand. The place names could be in English or te reo Māori (as in resource sheet 4.6).
Information transfer tasks of this kind encourage deep processing of information. You could use resource sheet 4.7 for another information transfer task involving the reomation Ngā tohu huarere mō āpōpō (Weather forecast for tomorrow), where the students provide text to correspond with the reomation pictures. More about information transfer tasks is also available.
As your students become confident with the language structures we use to describe the weather, they can take on the role of the teacher and write short weather reports to read to the class while their classmates record the appropriate symbols on a map.
