A pictogram uses pictures or symbols to represent data. A key shows the value represented by one picture or symbol. It is important to identify the value of the whole picture or symbol in a pictogram, as part symbols are often used to show lesser values. Discuss the pictogram below and explain what you can infer from the chart. Number of different coloured cars in Amy's Street 4 cars 4 cars 4

The key tells us that each whole circle represents 4 cars. As there are 2 circles in the 'black car' column we need to multiple this number by 4, so we know there were 8 black cars! Similarly we can use this knowledge to work out the total number of cars for each colour represented in the pictogram. 4 cars 2 x 4 = 8 black cars Black 6 x 4 = 24 silver cars Silver 1 x 4 = 4 blue cars Blue 6

First we need to work out the value of the whole circles and then the number represented by the fraction value. For example, there are 3 whole symbols in the yellow column, which represent 3 x 4 cars = 12 cars. However, there is also half a circle in the yellow column, half of 4 is 2, therefore to get the total number of yellow cars we must 4 cars complete 12 + 2 = 14! Yellow 3 x 4 + 2 = 14 yellow cars 7

There are 2 symbols in the red column, which represent 2 x 4 cars = 8 cars. However, there is also a quarter of a circle in the yellow column, a quarter of 4 is 1, therefore to get the total number of red cars we must complete 8 + 1 = 19 4 cars Red 2 x 4 + 1 = 9 red cars 8
