Roll a Ratio Table is a computational game that can be used to reinforce students’ ability to generate a ratio table from two values and to use a unit rate, ratios with an equivalent quantity, or any ratios from separate tables to determine the table with the lower ratio of x:y. This game based lesson can be used at various times in the lesson cycle. In 6th grade, it can be used as skills practice after students have been introduced to the skill, or as a review lesson. For 7th graders it can be used to re-activate a pre-requisite skill.
The game also comes with the following supplements:
- Instructional Considerations:
that highlight the skills and understandings that the game is designed to build. They also provide ideas about how to structure post game discussions, questions that can be asked of students to gather formative assessment data, and game extensions.
- Pre-Game Strategy Sheet:
where students generate an example problem they can use to guide them through the game. This page can serve as a scaffold until students are more familiar with the math procedures associated with each game.
- After the Game Strategy Sheet:
where students identify math vocabulary relevant to the game, demonstrate the math procedures they used during the game, justify the quantitative comparisons used when assigning points, and where teachers can quickly asses student progress in skill mastery.
- Skills Based Rubric:
that teachers can use to provide specific feedback to students on their skill progress.
The implementation of the lesson is as follows:
- Teachers demonstrate examples of how to calculate unit rate, and students record the examples on their Pre-Game Strategy Sheet. This is a great opportunity to uncover multiple methods of which students can self-select which method is most comfortable for them.
- Students play the game and record their work on the provided activity sheet. Even though games are played in pairs, each student should complete their own individual activity sheet. Students can use their Pre-Game Strategy Sheet as a guide during game play.
- Teachers can assess student work by either using the skills based rubric or by reviewing students’ responses on the After the Game Reflection sheet.
