MFM1P – Foundations of Mathematics – Grade 9 Math Applied

Learning Targets:

• Interpret the meanings of points on scatter plots or graphs that represent linear relations, including scatter plots or graphs in more than one quadrant.
• Carry out an investigation or experiment involving relationships between two variables, including the collection and organization of data, using appropriate methods, equipment, and/or technology.

Minds On

Scatter Plot Diagnostic Assessment

Students will analyse the scatter three scatter plots given on the page comparing:

• Scatter Plot #1:
  Leg Length vs. Tibia Length
• Scatter Plot #2:
  Number of Baskets vs. Distance from the Basket
• Scatter Plot #3:
  House Price vs. Age of House

Students will then state whether they agree or disagree with the three statements next to each scatter plot.

Submit Your Results in the Google Form

Once complete, students will submit their answers via a Google Docs Form.

Think, Pair, Share

Answer the Statements & Compare

Students will complete the following relationship statements individually, then they will share their answers with a partner.

On the sheet, indicate whether you and your partner agree or disagree. If you disagree with your partner, have a conversation to determine which view makes the most sense and make the appropriate changes on your worksheet.

Action

Measure and Record Height, Forearm, Arm Span, & Foot Length

With a partner, measure and record each measurement to the nearest centimetre. Enter your data into the class data collection chart.

• In the HEIGHT column, measure total height.
• In the FOREARM column, measure from wrist to elbow.
• In ARMSPAN column, measure from fingertips on one arm, across chest to fingertips on other.
• In FOOT LENGTH column, measure from heel of shoe to toe of shoe.

Consolidate

Creating a Scatter Plot

Individually, students will now consolidate their learning by creating two scatter plots:

• Scatter Plot #1 – Height vs. Arm Span
  (Teacher-Led)
• Scatter Plot #2 – Forearm Length vs. Foot Length
  (Individual)
