    EXPLORE / TŪHURA learning intentions:

    • We are EXPLORING organising data using graphs.
    • We are EXPLORING interpreting data displays for information.
    • We are EXPLORING the term measure of centre and finding mean, mode, median and range.
    • We are EXPLORING analysing graphs using measures of centre.

    Activities:

    1. Warm up - CAT Revision - Measurement
    2. Frequency tables - what does the name suggest? what does frequency mean?
    3. Video on constructing a frequency table - https://www.youtube.com/watch?v=lyRbCwDDnJo
    4. Students construct a frequency table for a given question 
    5. Frequency tables - https://www.transum.org/Maths/Exercise/Tally/Charts.asp?Level=4
    6. Finding mean, mode median from a frequency table
    7. Stem and Leaf graphs - show examples  - which part is the stem and which part are the leaves?
    8. Go over an example with class on how to read and interpret a stem and leaf graph
    9. Finding mean, mode median from a stem and leaf graph
