Teaching strategies for the learning experiences and assessment opportunities

The teacher:

assesses students’ understanding of target language required for the unit of work
pre-teaches target language required for the unit of work
defines area as the amount of surface and models the concept of area by covering all parts of a surface without gaps or overlaps
supports students’ conceptual understanding by providing examples and non-examples of area
initially provides students with informal units that cover given surfaces/areas with no parts of units left over so that students can record whole units. Fractions of units are introduced after students have demonstrated an understanding of the concept of area.
questions students about why they selected particular informal units, eg ‘Why did you select a unit with a straight edge?’, ‘What happens if you try to cover the area with a unit with a curved edge?’
