Group: Elaine, Alice, Prem
Topic:
Math 8 Variables & Equations
model and solve problems using linear equations of the form Bridge:
Simple Word Problem:
Say on Sunday you went shopping, you bought 5 video games and in total you have spent $100. How much is it per game?
Take a minute to think........how did you come up with your answer?
Pre-Test:
The area of the rectangle is 35. What is the length of the unknown side?
Teaching Objective:
-To effectively teach the concept of solving linear equations
-To develop student's problem-solving/thinking ability
-To relate the Mathematics of the lesson to real-life applications
-To allow students working in groups and to encourage group learning
-To help students take responsibility of their learning by asking them to design a word problem using the concept learned
Learning Objective:
-Students will be able to solve for the unknowns of the linear equations by the end of the lesson
-Students will be able to design a real-life problem using the concepts they have learned
-Students will have the opportunity to present their learning and also to learn from each other
Participatory:
We will teach the PLO's on solving.
5 word problems to teach the equations.
Eqn 1: ax=b (introduced in Bridge)
Eqn 2: x/a=b, a is not zero
Agnes has a bag of candies. She distributed the candies equally to her five friends. It turned out that each of her friends received 3 candies. How many candies were in Agnes' bag in the beginning?
Eqn 3: ax+b=c
Find three consecutive integers whose sum is 258.
Eqn 4: x/a+b=c
Peter's teacher gave him a container full of 140 bricks.
One-sixth of the bricks were red and there were 20 blue bricks. How many red bricks were there?
Eqn 5: a(x+b)=c
Ask how they got their answers and do people have different methods of solving the problem.
Post-Test:
Make your own word problem (group) and present it with solutions to everyone.
Summary:
-We will adjust the amount of teaching accordingly under the time constrain
(we might not be able to teach all 5 main types of solving for linear equations)
-We want our students to understand the importance of the lesson and how applicable it is to our daily life
-We want to encourage students to have different methods of solving a problem
-We want our students to participate in their own learning
