[Lesson on 28 June FRI] Solving Word Problems using Equations (40min lesson)

In the previous lesson, you have been tasked to read up p14 and p15. 

Follow the following lesson sequence, and be ready to pause anytime to add notes as you watch the clips.

STEP 1 (est. 3 min)

Watch & Listen to the Introduction to solving word problem using equation (& algebra)

 

STEP 2 (est. 3 min)

Watch and make a connection between problem solving approach and Polya's 4 stages of Problem Solving.

STEP 3 (est. 3 min)

Read Example 5.

STEP 4 (est. 3 min)

Try Class Work 4 Question 1 if you have not done so.

Watch and listen to the clip to check your answers. 

STEP 5 (est. 5 min)

Try Class Work 4 Question 2 if you have not done so.

Watch and listen to the clip to check your answers. 

STEP 6 (est. 10 min)

Post a photo of your work in the Padlet - clues are in the 1st column of the Padlet.

Attempt only ONE question: Either Q3 or Q4. 

[Class work] Manipulation of Equation with 2 variables

A follow-up of last lesson's class discussion on the following, which most of you had clarified when you meet classmates doing the same question. We also went through the questions briefly at the end of the lesson.

The clip shows how the EXAMPLE is solved: 

Below are the links to questions assigned. 

Watch the clips to check your answers; do jot down any notes that you are still not clear. You may post it under the Youtube comment.
