14. Define and develop a probability model, including models that may or may not be uniform, where uniform models assign equal probability to all outcomes and non-uniform models involve events that are not equally likely.

a. Collect and use data to predict probabilities of events.

b. Compare probabilities from a model to observed frequencies, explaining possible sources of discrepancy.

27) Identify data needed to create a model or simulation of a given event.

Examples: When creating a random name generator, the program needs access to a list of possible names.

a. Collect and use data to predict probabilities of events.

b. Compare probabilities from a model to observe frequencies, explaining possible sources of discrepancy. [Grade 7, 14]

In this lesson, students will use an online spinner to explore theoretical and experimental probabilities. Students will also make predictions and support their reasoning before completing a probability experiment. Then students will design a spinner where all the sections are not uniform. To be able to compare results, the only variable changed is the size of the sections. Students will express probability results in both percent and fraction forms. Finally, students will reflect on a simulation of a given event.

13. Generate expressions in equivalent forms based on context and explain how the quantities are related. [Grade 7, 7]

In this activity, students will create equivalent expressions using an online tool. Students are provided two expressions and asked to find the value of the variable to make the two expressions equal. Then, students are provided an expression and a value of the variable and asked to generate a different expression equal to the original expression. Through the online digital tool, students are able to substitute values and develop strategies for creating equivalent expressions. This provides a great opportunity for students to investigate how to solve problems using multiple methods.
