  1. Starter Activity 5 minutes • 7505 ÷ 5 = • 12 – 6.01 = • 54 x 23 = • 15.4 – 8.88 = • 3,016 ÷ 13 = Reasoning

  2. TOPIC: Introduction to Bar Graph LESSON OBJECTIVE(S) 1. All of you will be able to identify types of graphs used in collecting, organizing and representing data 2. Most of you will be able to interpret data in tables, tally charts, frequency tables, pictograms and bar charts 3. Some of you will be able to compare representations where scales have different intervals KEY WORDS 1. Pictograms 2. Bar charts 3. Frequency table 4. Tally charts 5. Interpret 6. Scales 7. Intervals

  3. BAR GRAPH A bar graph is a chart that uses bars to show comparisons between categories of data. The bars can either be horizontal or vertical. A bar graph will always have two axes. ADD A FOOTER

  4. Bar Charts Data that is counted and has no in-between value is called discrete data. Discrete data is usually collected in a frequency table and then presented as a bar chart. A bar chart has a horizontal axis and a vertical axis. • A bar chart must always have a title explaining what it shows. • Bars must be carefully drawn to show the data. • There must be a gap between each bar. • Each bar must be the same width. A number line is marked on the vertical axis. The scale of this number line is chosen based on the data range. The data categories are organised on the horizontal axis. Each axis must have a label explaining what it shows.

  5. Interpret and present discrete and continuous data using appropriate graphical methods, including bar charts and time graphs Look at the bar chart then answer the questions.

  16. Pictograms A Pictogram to Show How the Children in KS2 Travel to School Key: = 2 children Key: = 4 children A pictogram uses pictures or symbols to represent discrete 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 different values. A Pictogram to Show How the Children in KS2 Travel to School In both of these pictograms, the data is the same but the value of the symbol is different.

  35. Favourite Children’s Toys of the 1980’s. (it wasn’t that long ago!!!) When we are collecting information and data about a particular topic, we need to do so in an organised way, so that we can later present it. Miss Crawford asked 50 friends (25 boys and 25 girls) from when she started school in 1988 what their favourite toy was from a selection of 8 popular toys of the time. The choices were as follows: (On the Next Slide)
