Math K-7 IRP Statistics and Probability (Data Analysis)

Students collect, display, and analyse data to make predictions about a population.


Prescribed Learning Outcomes Illustrated Examples
It is expected that students will:
  • collect first-hand information by counting objects, conducting surveys, measuring, and performing simple experiments
    		• -> Which flavour of ice cream do your classmates like best? To find out if they prefer vanilla, chocolate, or some other flavour, survey each of your classmates and record each answer on the class list.


    Use blocks on the graphing mat to show what you learned.

    What are three things your graph shows about ice cream flavours? Make up a question you might ask a friend about your graph.
  • sort objects by one attribute chosen by themselves or the teacher
    		• -> Here is a collection of pattern blocks, two of each shape and colour. What is one rule you might use to sort the blocks into exactly two groups? Sort the blocks by your rule. How many blocks fit your rule?

    Without looking, tell how many blocks do not fit your rule. How do you know? Make a new rule for sorting the blocks and sort them by your new rule. How many blocks fit your rule? How many do not?
  • construct a pictograph using one-to-one correspondence
    		• -> Make a pictograph to show how many like swimming and how many donžt like it.

  • compare data using appropriate language, including quantitative terms
    		• -> This is Marcožs graph. He wanted to know how many of his classmates have a dog for a pet. How many children did he survey? What did he learn?

  • pose oral questions in relation to the data gathered
    		• -> What do you think this graph is meant to show? What needs to be written down before everyone can understand the graph? What is a question you might ask a classmate about this graph? Can you think of another question to ask?
