Procedure Period 1 1. Introduction 1) Review knowledge about counting numbers by asking questions Teacher : What are counting numbers? Answer : Counting number are 1, 2, 3, 4, … 2) Playing a game with counting numbers - student counting the number one by one (counting from 1-100) 2. Lesson Procedure 1) Teacher represent the integers on the white board. - Whole number : 0, 1, 2, 3, … - An integer is a whole number that has a positive sign (+) and negative sign (-). - A positive integer is a whole number with a positive sign or without any sign. - A negative integer is a whole number with a negative sign. - Represent the integers on a number line. 2) Practice reading the integer: All students reading the integer in figures and words Example +10 = positive ten or ten +58 = positive fifty-five or fifty-five +237 = positive two hundred and thirty-seven +3,468 = three thousand four hundred and sixty-eight -9 = negative nine -21 = negative twenty-one 3) Game : State the integers - The teacher write the number on the whiteboard and then randomly assigned student to state the integers by marking a tick or marking a cross. 5 Example 2 -8 1 3 2 0 1 4 3.58 -2,089 -45.70 823 -124 3. Conclusion 1) Students and teacher share conclusions about integers: that is - Integers are can be positive integers, zero and negative integers - We can represent the integers on a number line. - We can represent the integers in figures and words. 2) Homework: 1. Represent the integers in figures and words from -100 to 100 2. Exercise1. (in E-Mastery PLUS Mathayom 1, page 13) 3. State the integers from the list below 1 Example 1) 30, -4, 4 , 0, 4.25 2 Solution 30, -4 and 0 Period 2 1. Introduction 1) Ask students, what we learned at the end of the previous lesson. Answer: Integers 2) Ask students to state the integers from the list: 2 Example 7, 3.18, 3 , 0, -2 Answer : 7, 0, -2 5 2. Lesson Procedure 1) Ask student to represent the integers from 20 to 30 by use a number line Answer 6 2) Ask a few students to represent the following integers by using a number line. (a) -4, -3, -2, -1, 0, 1, … (b) -15, -10, -5, 0, 5, 10, … (c) -7, -4, -1, 2, 5, 8, … Other students and teacher share discussion of solution 3) Open the E-Mastery PLUS Mathayom 1 on page 13, all student take an exercise 2-3. All students and teacher share discussion of solution. 4) Teacher represents a few sequences of integers on the white board then ask students to complete and share discussion of solution. Example Sequence : -6, -4, …., 0, 2, …., 6, 8 Answer : -6, -4, …2..., 0, 2, …4..., 6, 8 3. Conclusion 1) Students and teacher share conclusions about integers: that is - We can represent the integers on a number line. - We can represent the sequence of integers. 2) Homework: 1. Complete each of the following sequence of integers (exercise 4-5 in E-Mastery PLUS Mathayom 1, page 13) Period 3 1. Introduction Review knowledge about comparing numbers by asking a few questions. Teacher : Which integers is smaller, 2 or 5 ? Answer : 2 Teacher : Which integers is greater, 7 or 18 ? Answer : 18 2. Lesson Procedure 1) Teacher represents a number line of integers on the white board and say that “Any number on the right is greater than any number on the left”. 7 decreasing increasing Example 3 is greater than 0, 0 is greater than -1, -5 is smaller than -4 and -3 is smaller than zero. 2) Asking a few questions: Example Teacher : Which integer is greater, -4 or 3 ? Answer : 3 3) Student take exercise 6 in E-Mastery PLUS Mathayom 1 at page 14 then all students and teacher share discussion of solution. 4) Practice reading the mathematical symbols = is equal to is not equal to > is greater than < is smaller than is smaller than or equal to is greater than or equal to 5) Practice reading the mathematical sentence Example 5 > 4 5 is greater than 4 -12 < -9 -12 is smaller than -9 3. Conclusion 1) Students and teacher share conclusions about comparing the integers: that is - Any number on the right is greater than any number on the left - Any number on the left is smaaller than any number on the right 2) Homework: exercise 7-9 in E-Mastery PLUS Mathayom 1, page 13) 8.
