standard_description: Derive the formula A = 1/2 ab sin(C) for the area of a triangle by drawing an auxiliary line from a vertex perpendicular to the opposite side.
problem_activity: Activity
In this activity, students use a large data set to compare the size of students with different dominant hands. Students must select a variable that best represents the size of the students and compare the two groups. By selecting the relevant variable to analyze, students are engaging in aspects of mathematical modeling (MP4). Additionally, students must choose the appropriate tools (MP5) to analyze a large data set such as this.
Launch
Arrange students in groups of 2. Distribute a copy of the blackline master to each group.
Representation: Internalize Comprehension.
Begin the activity with concrete or familiar contexts. Engage in a classroom discussion drawing attention to the relationship between height, foot length, and arm span of right- and left-handed students in the class. This will help students make connections between the large data set and specific students in the class.
Supports accessibility for: Conceptual processing; Memory
Student Facing
Is there a connection between a student's dominant hand and their size? Use the table of information to compare the size of students with different dominant hands.
