To solve complex problems involving interpreting line graphs

To solve complex problems involving interpreting line graphs. Year 5 - Statistics (GDS) Lesson 2

LI: To solve complex problems involving interpreting line graphs. I can identify what the axes of the graph are measuring. I can following the X axis first and then the Y axis to read the graph. I can draw conclusion from a line graph. Vocabulary Line graph Time X axis Y axis Title Measure Patterns Conclusions Recap from the last lesson… Look at the skills and then quickly check your understanding. Previously, we looked at how we can read and interpret two-way tables and timetables. Let’s quickly recap the rules of reading tables. . . Two-way tables: Use the heading on top and on the left of the table to understand what is being measured. Remember two-way tables are usually measuring two different variables for example food and drink. In two way tables you can use the information to help you fill in any missing information. Timetables: Timetables are basically a schedule telling what time certain things will happen. The most common type is a train or bus timetable. The main thing you need to remember is that each column is a different train so it might be useful noting that down on your table.

Learning check: You do…. QUESTIONS: 1. Timmy arrives at Sowerby Bridge at 11: 25. How long will he have to wait to get the train to Hebden Bridge? 2. Stacey wants to arrive at Mytholmroyd by 11: 53. Which train should she take from Bradford? Answers: 1. 20 minutes 2. The 11: 10 train from Bradford. If you are struggling or didn’t get the correct answers, rewatch the video above which breaks down how to read timetables. If you feel confident, carry on with the slides.

Which year was it and which city did it hit? c) In which year was the smallest difference of population between the two cities recorded and by how much? Learning check: You do…. Answers: a) 26 b) 55 c) 92
