Grade 7 Math - Unit XV Overview

Probability

Throughout Unit 15, students will recognize the physical and mathematical models that can be used to describe the experimental and theoretical probability of real-life events. Students will generate sample spaces for simple and composite experiments using various models. From these models, students will determine the probability of a specific independent event.

Problem solving, language and communication, connections within and outside mathematics, and formal and informal reasoning underlie this unit. Students use these processes together with technology and manipulative materials to develop conceptual understanding and solve problems as they do mathematics. Emphasis should be on the problem solving strategies of Make an Organized List, and .

Critical Questions

  • Does the act of replacement affect the outcome of composite events?
  • How does the sample space relate to probability?
  • What is the similarities and difference between theoretical and experimental probability?
