Bar charts use bars to show amounts. The taller the bar, the bigger the value.
Always check the scale on the y-axis — each line might be worth 2 or 5!
Pictograms use pictures or symbols to show data.
🍎🍎🍎 = 3 symbols × 2 = 6 apples
Half a symbol = half the key value.
Venn diagram: overlapping circles show things that belong to two groups.
Carroll diagram: a grid sorted by yes/no for two properties.
A bar chart shows books read per week. The bar for Monday reaches 5.
A pictogram uses 🌟 where each 🌟 = 2. Row shows 🌟🌟🌟.

Table shows: cats=25, dogs=4, fish=7, birds=13, rabbits=6, other=2. Total pets?
Venn: Left circle (multiples of 2), Right circle (multiples of 3), overlap = multiples of both.
A bar chart shows favourite pets. Read the value for each bar.
Count the symbols and multiply by 2 to find the total.
Count each tally to find the frequency.
Use the frequency table to answer each question.
Table: Cats=25, Dogs=4, Fish=7, Birds=13, Rabbits=6, Other=2, Hamsters=9, Guinea pigs=5, Snakes=3, Turtles=8
A Venn diagram has Region A (left only), B (overlap), C (right only). Count the items in each region as described.
