CHAPTER AT A GLANCE
Finding the Unknown
•Unit: Algebra
•Board weightage: Framing and solving simple equations, the balance idea, equations with the unknown on both sides, checking the solution and word problems give regular 1-mark, 2-mark, 3-mark and 4-mark questions (please check the latest sample paper)
•Key ideas from the textbook: equation as a balance, trial and error, doing the same operation on both sides, inverse operations, unknown on both sides, framing equations from patterns and stories, creating equations with a given solution
•Most scoring part: writing each operation on both sides, then substituting the answer to check
•Time to revise: about 60 minutes
