Lesson Plan: A problem-solving activity about proportional relationships and the ratio concept in the context of maximising profit.

Subject: Mathematics.
Age of students: 11-14 years.
Hardware: Tablets (iPad 1 per class or student).
Software: Socrative or Classflow + Apple airserver
OR Showme and Reflector
OR Plickers.
Functionalities of Technology: Sending and displaying
Processing and analysing.
Time needed: 2-3 hours.

Summary:
This lesson is intended to help you assess how well students are able to solve real-life mathematical problems. In particular, students will develop their abilities in the following areas:

  • Using proportional relationships to solve multistep ratio and percent problems.
  • Drawing inferences about a population from a random sample of data.
  • Making and stating assumptions based on real-life situations.
