### Rancangan Harian Panitia Matematik

1. 1. PANITIA MATEMATIK Nama Guru : Pn. Umrah Dalimun M/Pelajaran : Mathematics Tingkatan : 3 KAA Topic : Linear Inequalities Time : 80 minutes Learning Area : Linear Inequalities Learning Outcome: 1. Identify the relationship a. greater than b. less than base on given situations c. using the symbols / sign “ > ” or “ < ” and “ ≥ ” or “ ≤ ” 2. Identify the relationship between 2 given number a. greater than or equal to b. less than or equal to base on given situations Learning Objectives: 1. student be able to understand and use the concept of inequalities 2. student be able to understand and use the concept of linear inequalities in one unknown 3. understand the sign “ > ” or “ < ” and “ ≥ ” or “ ≤ ” Learning Activities: Time Activities Achievement Step 1 1. Explain the sign in linear inequalities Student must know the (10 minutes ) i. greater than differences of the sign ii. < less than iii. ≥ greater than or equal to * notes: iv. ≤ less than or equal to Gives more example until student understand 2. Give the examples ini numbers a. 5 > 3 b. 4 < 7 c. -5 < -3 d. -4 > -7 Known as equivalent inequalities
2. 2. Step 2 1.Represented a linear inequality on a number Student achieve the sign in ( 10 minutes ) line number lines a. X > 2 1 2 3 4 b. X > 6 6 7 8 9 c. X < -1 -4 -3 -2 -1 d. X < 10 7 8 9 10 Step 3 1. Represented a linear inequality on a number Student must know the ( 10 minutes ) line differences of sign a. X ≥ 3 2 3 4 5 6 7 or b. X ≤ -1 -3 -2 -1 0 c. X ≥ -8 -8 -7- -6 d. X ≤ 10 7 8 9 10 Step 4 1. Explain the answer of inequalities: Student must find the ( 10 minutes ) example: differences of the answer . a. X < 5 .: X = 4 , 3 , 2 , 1 , 0 …….. To solve it student must know how to draw a number line to find the answer b. X > 3 .: X = 4 , 5 , 6 , 7 , 8 , …….. c. X < 5⅓ .: X = 5 ,4 , 3 , 2 ,1 , ……….. d X > 5⅓ .: X = 6 , 7 , 8, 9 , ………….
