Proportion and Non-proportion Situations
I used this resource in grade 7 , the details was good and enough , lesson plan was good organize and covered lots of activity , the power point was useful and can engage the high level students, it has problem solving from real life and this motivate and make the students attention.

This is a lesson where students can investigate Proportions. The lesson comes with many resources like a Pre-Assessment, activity templates, and detailed lesson plans. It also has a Powerpoint to match the lesson. It addresses CCSS: 7.RP.1: Analyze proportional relationships and use them to solve real-world and mathematical problems. Although the lesson suggests 2-3 days. It has taken my class more like 3-4 days to do these types of investigations. I would suggest giving the Pre-Assessment ahead of time to your class so you can grade it before starting the activities
