7th Grade Ratio and Proportion: An Example of Technology Integrated Classes


     
Components of the lessons:

First week: SketchUp as homework
Second week: Kahoot questions from students, Poster examining (Group work), Articulate Project, Research(Piazza)
Third week:  Individual work of research in class, Edpuzzle(competition), Kahoot.

 One week before the first class, it will be said students to construct buildings on Sketch-Up that are suitable with conditions that is given them. It will be given different conditions for each student. For example, it will be given a paper a student which is written these conditions:
  •  Construct a 3D shape; 1/12 of it is red, 3/6 of it is blue, 1/4 of it includes patterns or pictures, 1/6 of it constructed from a different shape. ( Each piece should have one characteristic like only being red)

 With these conditions, the student will construct a 3D shape on Sketch-Up. After all students construct shapes with conditions that are given, they will deliver it to teacher via an e mail which is attached Google Drive link of their 3D shapes. In first class, it will be given them blank papers to write 2 questions and their answers about their shapes. For instance, questions can be like:
  •      I have three red pieces in my shape. We know that 1/12 of my shape is red and 3/6 of my shape is blue. Then, how many blue pieces are there in my shape?
  •      2/12 of my shape’s pieces are cubes and the other pieces are rectangular prisms. In total, it has 36 pieces, then how many rectangular prisms are there in my shape?

 It will be collected all these papers and it will be wanted their shapes’ pictures. Then, it will be prepared a Kahoot that include these questions with their pictures and it will be applied this Kahoot next week in class.
 After, they wrote questions for Kahoot, they will discuss about a Poster that is written some statistics on it.


Firstly, it will be made students groups of four. Then, it will be wanted them to discuss these questions:
1) What can be the population of the children in Turkey according to information on Poster? (Population of Turkey is 78 million)
2) What is the ratio of the number of child labor to the population of whole children?
3) How many child labors go to school and how many of them don’t go to school?
Note: They can use calculators.
 While they are discussing, it will be observed all groups, if they need, it can be given some help. After all groups discuss it 30 minutes, they will choose a group leader and each leader will tell to the class how they found answers and what their strategies were.
 In the second lesson, it will be taken all students to the Computer Lab and they will use Articulate application that is prepared for this class. In articulate, they will learn about proportions, proportional relationship in real world. They will see their tables and graphics and also proportion constant. All these issues are not explained literally, but when they use the application, they will understand internally all of them. While they are using application, it will be observed students and if there is a problem it can be given help them. After all students finish application, they will talk about new concepts like proportion, proportional relationships, and constant of variation. Also, they will examine tables and graphics in Articulate Project and students will say their ideas about tables’ and graphics’ usage in proportions.
 It will be wanted them to make a research about proportional relationships in real world and they will write their findings on Piazza. It will be important to write sources of their information and making cites. Also, they can discuss and make comments about the findings of each other.
Next week, in first class, they will start to lesson with examples in their research. It will be wanted them making their examples’ tables and graphs. Also, they will find constant of variation in their examples. They will work individually, and the teacher will be around to observe and help them while they are making this work. The following is an example of this work.
Rose can download two songs from the Internet each minute. This is shown in the table and in the graph.
Find the constant of variation.
Notice that as the number of songs increases by 2, the time in minutes increases by 1.





Constant of variation =songs per minute.
                                                      

 After the teacher makes sure all students had done it, the teacher will want each student to say what he or she has done in his or her work with 2 or three sentences.
 In the second class, it will made students groups of four and it will be showed this video that is prepared on edpuzzle. When it is came to the question marks, groups will show their answers that are written to a paper and the fastest and most correct group will win the competition. If they want to watch it again they will login the edpuzzle and they will enter this code: gabcunm

Finally, at the end of the class, it will be applied Kahoot that is prepared with the questions that students wrote about their 3D shapes previous week.
