Statistics - Draw pictograms 2, 5 and 10 - Presentation

The teaching slides for Year 6 statistics introduce the concept of drawing pictograms with symbols representing 2, 5, or 10 units. The first activity involves helping Leanna record the number of fruits seen at a fruit stall by completing a pictogram. The key initially indicates that one symbol equals one piece of fruit. Students are prompted to identify issues with the pictogram and consider the effects of changing the key. They are asked which key they prefer and why, encouraging them to think critically about the representation of data.

Further activities explore the theme of communication with relatives via face-time. Students are tasked with drawing a pictogram to represent the number of calls made to different family members. They must determine the appropriate key for the pictogram, considering that twenty grandmas were called, twice as many uncles as grandmas, and five fewer cousins than uncles. The key changes from representing 10 relatives called to 5, and students must adjust their pictograms accordingly. The exercises challenge students to think about the representation of partial units, odd numbers, and the most suitable symbol values for different quantities. A final discussion prompts students to consider when to use symbols for different values and how to accurately represent data in a pictogram.
