In this practical task, students design a tally chart to record the number of different coloured ice-block sticks in an envelope. Students use the sticks as tally marks.
Students conduct a practical, statistical investigation. They decide on a question, categories, conduct the survey, tally and graph the results on a bar graph.
Students find the number of groups of a given size using division, reverse multiplication, trial and improvement, or iterative equal sharing. Students must show their working.
