architects do. They will have to find the best possible proportions to create safe and attractive buildings. Agenda: Opening (5 minutes): Students will review vocabulary words and answer some questions about ratios. Students will show on a double number line how to find ratios and how to write them correctly . Lesson and Activities (20 minutes): Students will be given an example problem in which a batch of purple paint is being made with 2 cups of blue paint and 3 cups of red paint. They will then be told to figure out how to display the same relationship but for 20 batches of the purple paint; they will use connectable colored blocks to show this relationship but must also be able to explain their reasoning on paper with their group. Assessment and Closure (35 Minutes): Students will stay with their group and begin the Ratio Challenge online or on a tablet. As a group, they must choose which building they would like to design (baseball stadium, amusement park, or aquarium), work out all the ratio problems to find correct proportions, and digitally create the building. Students must show all their computations on a paper and collaborate on what strategies to use. Each group will share their finished project with the class, explaining their process. To close class, students will be led in a discussion on why proportions are so important when it comes to building things and what possible negative effects could arise in real life if proportions were not correct. Formative assessment: As the students are working in groups to create their building designs . The teacher and Aide will walk around the room and ask questions to see if the students understand what they are doing. The students will use worksheets using ratios and proportions for classwork and homework in order to demonstrate their understanding of the lesson. The students will also demonstrate their understanding on the mid-week quiz and on Friday’s test. Academic Language: Key vocabulary: Ratio Proportions Equivalent Function: They need to know these key vocabulary words in order to understand what function they will be performing. Form: In order to teach the student’s, the key vocabulary I will have them use their color cube blocks to build a model. While the students are building their models. I will implement the key vocabulary words and give them the definition as the work.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
