### 24 Feb: Things we accomplished and Getting Ready for the Next Lesson

In the first two lessons of this week (Monday & Wednesday (today)):
• We discussed several questions in the Maths blog and used Paul's Wheel of Reasoning to check the assumptions when making decisions (e.g. whether one expression is greater/ equal/ less than another expression)
• On Substitution type of questions, we should carry out the steps systematically (step by step):
• Substitute the values into the expression correctly, especially when powers and roots are involved
• (follow by) Evaluating the arithmetic expression
• Reminder: Express your answer as a mixed number (instead of an improper fraction)
• We carried out error analysis of the 2 questions in the blog
• Answers in Lesson 1 (p5) were checked and discussed
• The class identified 3 questions in Assignment 4.1 for discussion before submitting it.

Preparation for next lessons (Thursday, Periods 1 & 2)

(A) Lesson: Algebra
• We will be discussing Lesson 2: Simplifying Algebraic expressions (involving 4 operations).
• Go through Study Notes (Lesson 2) and attempt Assignment 4.2 (for discussion)
• At the end of the lesson, you should be able to answer the challenging questions:
(B) Revision
Bring your marked assignments, as well as the 2014 S1 Level Test 1 question paper.
We will start the revision discussion at the 2nd period.
