Learning Task A. Introductory Activity Daily Routine Cleaning of classroom Checking of attendance Checking of assignment Priming “MathirangMathibayContest“ Instructions: Form a team or group the students with eight members. In their team let them answer Round I and Round II. The team with the highest total points will win the game. Round 1: Fun Ways to Think “Picture Edition” See and analyze the picture below. Then guess the hidden word correctly. Write your answer inyour drill board. Rubric The first team or group that can give the answer correctly will have 5 points. The rest of the team will have 0 point. ___ O ___ N A ____ + = T ___ ___ M + ___ A ___ T ___ ___ ___ B.

TABLE A ROW 1ST TERM 2ND TERM a. 1 5 b. 2 6 c. 3 7 d. 4 e. 5 f. 6 g. 59 Analysis Using Table,A as your basis, answer the following questions: 1. How did you find the activity? 2. What did you do to determine the 2nd term for rows d to f? 3. What did you do to determine the 2nd term for row g? 4. What is the relation between the 1st and 2nd terms? 5. Express the relation of the 1st and 2nd terms in a mathematical sentence Abstraction Constants and Variables Mathematical statements use two types of quantities: constants and variables. A constantis any symbol representing fix value. A variableis any symbol representing possible value of quantity. Examples:Identify the constants and variables in the given expressions: a. 5x-1 b. 2 𝑟 c. a+ 3 b Application Identify the constants and variables in the given expressions: Algebraic Expressions 1. 8xy + 2 2. x + 3y 3. 5a + 2b 4. x – 7 5. 3r – x 6. ½ xr2 7. x/2 (x + 4) 8. x + y + 2z 9. 20x2y2 + 11 𝑥+4 10. +5 3 Constant(s) 8 and ___ 2 and ___ Variable(s) x and ___ y and ___ b and ____ 3 and ___ x and ___ 2 and ___ 11 and ____ 4, ___ and ___ x, ___ and ___ y and ___ IV.
