Ratios: A Focus on Part-Part and Part-Whole Relationships (Grade 6)

Students will analyze ratios and proportional relationships and discover that the relationships are multiplicative rather than additive. Students will recognize that ratios, unlike fractions, can involve both part-part and part-whole comparisons. They will generate equivalent ratios by partitioning and iterating composed units, use a variety of representations to respond to a problem situation, and weigh the advantages and disadvantages of such representations.  

Through engaging in the lessons in this lesson set, students will:  

• represent, analyze, and look for patterns or relationships; 
• make sense of concepts; and 
• develop, support, and defend claims and arguments.
