I can solve problems using data from a line graph
Line graphs usually show a change. You may be asked questions like: 1) What was the temperature in July? To find this, draw a line up from July until it meets the line and then along to the temperature. (Look at the pink line). The answer is 16oC 2) What month had a temperate of 8oC? This time, draw a line from the temperature and then down to the month. (Look at the black line). The answer is October.

I can solve problems using data from tables and timetables
Timetables look a bit different to normal tables.
To solve problems with tables it's important that you read the headings and then the information that falls under each one.
The top row (Mill Road) shows the time when four different buses start their journey. The middle rows (High Street and London Road) shows the time that each bus arrives at these locations. The bottom row (Green Avenue) shows the time that the bus ends its journey. There are four columns which means there are four different buses. Each number is a time.
Example question: What is the price of 2 adult and 2 child tickets on a Saturday?Answer: £9 + £9 + £7 + £7 = £32

I can solve problems using data from a bar chart
Bar charts have a vertical and horizontal axis with each bar showing a new category.Example questions: 1) What was the temperature on Thursday? Find Thursday on the chart and then read of the temperature from the top of the bar. Answer: 20oC 2) How many days had temperatures above 18oC? Find 18oC and see which bars are taller than this temperature. Answer: 2 days (Thursday and Friday)

I can solve problems using data from a pictogram
Pictograms are charts that use pictures or shapes. It's important to read the key next to the pictogram so that you know what each picture represents.
Key: = 2 ice creams The totals number of ice creams sold on each day are... Friday = 10 ice creams Saturday = 12 ice creams Sunday = 11 ice creams

I can solve problems using data from a pie chart
To read a pie chart you have to judge the fraction that a colour takes up.For example: this pie chart shows how 30 children get to school. If we wanted to know how many walked to school (blue section) we would estimate that it is half of the total children, as half has been coloured blue. The total number of children is 30 and half of 30 is 15 so 15 walk to school.

I can find averages, including the mean, median, mode and range
There are four types of averages: (Click on each one to learn how to find them) If you are asked to find the 'average' and it doesn't tell you which one, then find the mean.
