1. 30 October, 2022 Typical questions: Set notation set   : “A collection of things or objects“ Each object is called an element or member of the set .   List three members of the set {days of the week} O = {1, 3, 5, 7, 9, 11} List the subset P = {prime numbers}

2. Example Your Turn List the members of the set List the members of the set Example Your Turn Set notation

3. Set notation 1. For each of the following, write down two more members or elements of the set. Be ready to debate and defend your choices. a) { a,b,c,d , …} b) {France, Germany, Italy …} c) {1, 8, 27, …} d) {red, green, blue, …} e) {H, O, N…} f) {55, 11, 22, …} g) {mm, inch, cm…} f) {square, kite, trapezium…} h) {M, A , T, …} 2. List all the members of these sets a) {Days of the week} b) {Months of the year} c) {Factors of 10} d) {Factors of 12} e) {Factors of 7} f) {Factors of 16} g) {Types of triangle } f) {Types of angle} h) {Types of equal sided quadrilaterals}

4. Set notation 1. For each of the following, write down two more members or elements of the set. Be ready to debate and defend your choices. a) { a,b,c,d , …} b) {France, Germany, Italy …} c) {1, 8, 27, …} d) {red, green, blue, …} e) {H, O, N…} f) {55, 11, 22, …} g) {mm, inch, cm…} f) {square, kite, trapezium…} h) {M, A , T, …} 2. List all the members of these sets {Sunday, Monday, Tuesday, Wednesday, Thursday, Friday, Saturday} {January, February, March, April, May, June, July, August, October, November, December} {1, 2, 5, 10} {1, 2, 3, 4, 6, 12 } {1, 7} {1, 2, 4, 8, 16} {Scalene, Isosceles , Equilateral } {Acute, Obtuse, Right angle, Reflex} {Square, Rhombus}
