standard_description: Construct and interpret two-way frequency tables of data when two categories are associated with each object being classified. Use the two-way table as a sample space to decide if events are independent and to approximate conditional probabilities. For example, collect data from a random sample of students in your school on their favorite subject among math, science, and English. Estimate the probability that a randomly selected student from your school will favor science given that the student is in tenth grade. Do the same for other subjects and compare the results.
problem_activity: Activity
In this activity, students practice making connections between different representations of the same situation. If desired, they can also identify and create any missing representations (this would require removing some cards from the sets you distribute). The practice will be helpful when students make connections between verbal and tabular representations in the associated Algebra 1 lesson. A matching task gives students opportunities to analyze representations, statements, and structures closely and make connections (MP7).
Launch
Arrange students in groups of 2. Distribute 1 set of slips from the blackline master to each group. (A complete set if students will only do the matching. A set that is missing a few cards if you would like for students to create some representations.)
Student Facing
Your teacher will give you a set of cards. Each card has either a verbal description, a table, or a graph. Find the three cards that represent the same situation. If one of the three representations for a situation is missing, use the blank cards to create that representation.

Activity Synthesis
Select groups to share their matches and how they determined which verbal descriptions, tables, and graphs were a match. Look for groups that created different representations for the missing ones. Attend to the language that students use to describe their matching representations, giving them opportunities to describe them more precisely.
