To Parents and Adults at Home…
Your child’s class is starting a math unit on statistics (data analysis).
In this unit, your child will learn:
SP5.1 Differentiate between first-hand and second-hand data.
SP5.2 Construct and interpret double bar graphs to draw conclusions.
They will know that:
• Tables and graphs can be interpreted as data.
• Data can be displayed in a variety of ways.
• Data can be collected and organized.
• Data can be collected from a sample, rather than from an entire population.
• Inferences can be made from data displayed in tables or graphs.
• Data can be used to make predictions.
They will gain skills to be able to:
-recognize the difference between first and second hand data
-compare a bar graph and double bar graph
-create a double bar graph
They will inquire:
When might you use first-hand or second-hand data in a real life situation?
Can you differentiate between first and second hand data?
What is the difference between a bar graph and a double bar graph?
Can you create a double bar graph?
Watch for examples of tables and double bar graphs in newspapers,
magazines or on the internet.
Ask your child what the tables or graphs convey.
