Class Happenings - Numeracy

Kindergarten and year 1 students have been investigating the properties of 3 D objects. Students categorised the shapes according to how many faces each object has. Then they counted corners – vertices and edges. Running their fingers along each edge.

Year 2/3/4 have been using pattern shapes to investigate area, symmetry and tessellations. We played celebrity heads with 2 D shape names and students wrote questions about shape properties to give clues as to which shape they were.

Symmetry

Year 5/6 have investigated Statistics and Probability. We began with a task of gathering data using tally marks then graphed the results. Then we picked different coloured counters from a collection of 20. Students then assigned fractions, decimals and percentages of the picks, once they discovered what the value of each counter represented, it was easier to achieve.
