Students have learned that:
- a pictograph displays information using symbols instead of numbers
- each symbol represents a specific number or amount
- when creating a pictograph, we must also creat a key or legend
- when only half the symbol is displayed, it means just half the amount (as per the key) is represented. So if one happy face represents 4 people, then half a happy face represents 2 people
- when creating your pictograph, it's best to stick with one symbol representing an even number
- there will be times when we are asked to interpret pictographs where one symbol represents an odd number, but we'll cross that bridge when we come to it
- your ruler is a very important tool when creating pictographs (or an graph for that matter)
- the biggest mistake students make when interpreting data from pictographs is to count each item displayed as "one" and ignore the key
- we use surveys and polls to ask questions and then create different kinds of graphs such as pictographs, to display this information
