Lesson Plan: Introduction to Equations (Tues W1) Unit Title: Equations Stage: Lesson Title: Introduction to Equations Class: Content Strands: Number & Algebra 4 Year: 7 Duration: 40 minutes Rationale: Resources: Prior Knowledge: • Solving simple one and two step linear equations using algebraic techniques is an important skill for numerically literate citizens. • • • • • • • Understanding mathematical conventions when writing algebraic expressions • It is important that students can distinguish between algebraic expressions and equations and that they understand the significance of the ‘equals’ sign. Equations Pre-tests (55 copies) Equations Pre-test solutions (1 copy) Selected exercises from 9A & 9B (30 copies) 9A & 9B solutions (30 copies) Textbooks H/w questions on whiteboard • An understanding that pro numerals can represent variables and values can be substituted into algebraic expressions Outcomes: Indicators: Assessment: • MA4-1WM • distinguish between algebraic expressions where pro numerals are used as variables, and equations where pro numerals are used as unknowns. • Pre-tests (formative) • MA4-2WM • MA4-3WM • MA4-10NA • Whole class discussion/ questioning when working through pre-test solutions • Observation/ teacher questioning during exercises • Worked problems from exercises 9A & 9B Timing Content 10 min Equations Pre-Test Comments - Does not go towards anything! - Don’t stress if you have no idea, because we are going to cover all of this in the next few weeks. Just give it a go! 10 min Work through the solutions as a whole class Collect pre-tests. Hand out fresh copy of pre-tests to work through as a whole class. Students can write on these as the class works through the problems. - Don’t worry if you didn’t see it straight away. There’s a simple step-by-step way of solving these questions. We will learn about it in the next few lessons. - 8=3+5 - For this topic let’s get into the habit of thinking of the equals sign as ‘is the same as’. - 8=3+5=1+2+5=2*4 Make sure name is on test! 20 min Hand out worksheets Exercise 9A 1 b, e, h 3 5 m, n, o 8 c, f, i 9 10 11 12 13 14 Exercise 9B 8 b, d, f 9 10 12 Ext: 13, 14 Homework Finish the two exercises before Thursday Specific Links to Quality Teaching: Evaluation: Have students met expected outcomes of lesson? What worked well within the lesson? What did not work so well? How could you improve this lesson?
