Nicole Coots Pamela Solarz Lesson Title Comparing Groups of Numbers Introduction to Ratios Class 6th grade Sources Elementary and Middle School Mathematics Teaching Developmentally Activity p 355 Figure 19 2 b p 357 Activity 19 2 p 359 Related Standards EALR 1 The student understands and applies the concepts and procedures of mathematics Component 1 4 Understand and apply concepts and procedures from probability and statistics Grade Level Expectation 1 4 6 Determine and explain how data can support a point of view Objective Given an opportunity to make comparisons of ratios students will apply mathematical concepts and procedures to determine and explain their points of view Materials Three different types of math manipulatives EX 4 rectangles six circles and three triangles Room Arrangement Preferably desks or tables arranged in four spaces for group work Agenda Introduction Warm up pre assessment Group exploration Follow up discussion Procedures Phase 1 Today we will be comparing two sets of numbers I want everyone to know today is an exploration day There are no wrong answers only learning happening by trial and error So feel free to take some risks and think outside the box Comparing to sets of numbers can tell us many different things so there will be lots of correct comparisons Remember one of our biggest jobs is explaining our thinking both out loud during group work in our journals and during our follow up discussion I will be calling on folks who can explain their reasoning so remember to be thinking about your thinking Phase 2 We will begin with an individual warm up this also serves as a pre assessment so do your best work Please take out your math journals and tell me which group of shapes has more circles Remember there is more than one way to think about this problem Reflect on the problem in words pictures symbols just remember to show your thinking teacher displays two groups of shapes one group has four rectangles and three circles the other group has three triangles and three circles Phase 3 Next we will break into four learning teams to tackle your next comparisons Remember to work together Explain your thinking and make sure everyone is understanding because after all a team that leaves a player behind also fails itself Learning is our goal not completing the task the quickest After all these are hard problems that require deep thought Working quietly in silence to generate ideas might be a good strategy before you start sharing I will be handing out worksheets Your task is find mathematical arguments for why each dieter was the most successful We will be meeting for follow up on the rug in 30 minutes Phase 4 Student groups present their points of view Phase 5 Today our follow up journal write is our post assessment Please record your findings in your journals Show your thinking using pictures charts other visual organizers and words Assessment The two journal writes and would be compared to each other utilizing the following rubric Given an opportunity to make comparisons of ratios students will apply mathematical concepts and procedures to determine and explain their points of view Given an opportunity to make comparisons of ratios students will apply mathematical concepts and procedures to determine and explain their points of view Emerging Student may understand concepts but has a hard time articulating or writing their thinking Student may understand concepts but has a hard time articulating or writing their thinking Proficient Student may have one way of understanding two groups of numbers Students may lacking in their ability to either verbalize or write their thinking Student may have one way of understanding two groups of numbers Students may lacking in their ability to either verbalize or write their thinking Exceeding Student can understand multiple ways of viewing groups of numbers and explain their thinking verbally and in writing Student can understand multiple ways of viewing groups of numbers and explain their thinking
