Multimedia Workshop Week 1- May 30, 2016 Jamie Wolek Heritage Middle School Rates and Proportional Relationships

Target Audience Heritage Middle School 7 th Grade Mathematics Group of students 2-3 day lesson

Essential Questions How can you use rates and ratios to describe real world situations? How do we use proportional relationships to solve real world problems? How can you use proportions to help make decisions?

Big Ideas A ratio compares two quantities using division. A rate is a ratio with different units. Rates and ratios can be compared and reduced as previously learned in the fraction unit. Equivalent ratios form a proportion. Proportional reasoning is used to make real world decisions.

Objectives Students will be able to write ratios, compute and compare rates and unit rates. Students will understand how rates and ratios can describe real world scenarios. Students will understand that decisions in their own lives can be made based on proportional reasoning.

Evaluation & Assessment Students complete and submit online assignment. Student discussion and participation in classroom activities. Written class assignments. Student posts and comments in class Facebook group page and live chat.

Social Media/Facebook Students will research real world uses of rates and ratios and share their findings with the whole class on Facebook. Students post questions and respond with comments to questions posted by classmates. Students make and justify real world decisions based on application of new knowledge. Students work collectively to complete assignments by using live chat features while working in separate locations.

Multiple Intelligences Kinesthetic – physically visiting stores to research unit prices. Logical – all mathematical computations and decisions based on sound reasoning. Visual Spatial – proportional relationships are represented using tables, charts and graphs. Naturalistic – concepts are related to decisions students will make in their own lives that affect their world. Saving money vs. wasting resources. Linguistic – new vocabulary is introduced and used. Students take notes and answer questions in their own words. Compare/contrast charts. Interpersonal – students are required to participate in group discussions both inside and outside the classroom. Students use social media to interact with each other and posts questions and comments for classmates to respond. Intrapersonal – students are assigned individual work and answer keys are provided so they can self check. Open ended questions are answered individually during note taking exercises.

Make up questions that use unit prices to compare common products. Create both “fair” and “unfair” scenarios. Make and justify decisions based on evaluation of different rates and ratios. Analyze new vocabulary for similarities and differences. Express the same rate using different units to see which is most useful in a real world scenario. Apply new information to a variety of multi step real world problem solving scenarios.. Show understanding by participating in class discussions and completing written classwork. Remember fraction operations and apply concepts to ratios and proportions.
