1. What are we going to do? CFU We will solve and interpret 1 problems using a Venn Diagram 2 and set theory. Learning Objective Activate Prior Knowledge If we look at the following set 3 of numbers 1-20, we can find many different qualities that are unique, but that also have common characteristics as well.

2. Venn Diagram - Triple Concept Development A Venn Diagram is a collection of two or more sets of data (numbers, information, etc.) Representing information using Venn Diagrams allow us to see similarities and differences. Venn Diagrams are an easy way to show similarities and differences visually using a graphic organizer. How many individual sets are shown in the Venn Diagram to the left? Explain what the overlapping regions represent. CFU Suspense Only Drama Only Comedy Only Suspense / Drama Suspense / Comedy Comedy / Drama Suspense / Drama / Comedy Three sets

3. Union & Intersection Concept Development A Venn Diagram is a collection of two or more sets of data (numbers, information, etc.) Representing information using Venn Diagrams allow us to see similarities and differences. Venn Diagrams are an easy way to show similarities and differences visually using a graphic organizer. What do the Sets A and B represent? Explain what the overlapping regions represent. CFU When two sets of data have some items that are common, they can be represented as overlapping circles in a VENN DIAGRAM. This is called the Intersection. Intersection shows the what Set A and Set B have in common.

4. Union & Intersection Concept Development A Venn Diagram is a collection of two or more sets of data (numbers, information, etc.) Representing information using Venn Diagrams allow us to see similarities and differences. Venn Diagrams are an easy way to show similarities and differences visually using a graphic organizer. What happens when Set A and B are combined? CFU When two sets of data are combined in a VENN DIAGRAM, they become one. This is called the Union of the data. Union shows the what Set A and Set B have in total.

5. Identify what each Set contains. Identify what items are common (these are called intersection ) Without writing duplicates, list all terms in numerical order. This is the union U Union / Intersection. 1 2 3 How do you find the intersection? What does the union show? CFU 2 3 Skill Development/Guided Practice A Venn Diagram can compare information from two or more sets. Typically, Venn Diagrams compare either two or three sets of data. Areas where sets overlap show similarities, while areas that do not intersect show differences.. Intersection / Common Terms Union / All Terms { 10, 20, 30} { 10, 15, 20, 25, 30, 40, 50} Intersection / Common Terms Union / All Terms { 50 } { 10, 20, 30, 40, 50, 55, 60, 65, 70}

6. Identify what each Set contains. Identify what items are common (these are called intersection ) Without writing duplicates, list all terms in numerical order. This is the union U Union / Intersection. 1 2 3 Skill Development/Guided Practice How do you find the intersection? What does the union show? CFU 2 3 Intersection / Common Terms Union / All Terms Intersection / Common Terms Union / All Terms { grape, orange} { grape, orange, cherry, ginger ale, lemon-lime, cola, cherry cola, root beer, grapefruit} { a, e, i} { a, b, c, d, e, f, g, h, i, o, u, y} alphabetical

7. What are the sets you are asked to compare? (Pair-Share) How can you label sets? (Pair- Share) CFU Relevance Vocabulary Prime: number with exactly 2 factors. Odd: numbers ending in 1,3,5,7,9 Even: numbers ending in 2,4,6,8,0 PRIME ODD EVEN 2 4 6 8 10 12 14 16 18 20 2224 26 28 30 32 34 36 38 40 42 44 46 48 50 3 5 7 11 13 17 19 23 29 31 37 41 43 47 1 9 15 21 25 27 33 35 39 45 49

8. What did you learn today about Venn Diagrams and Set Theory? (Pair-Share) Use words from the word bank. Summary Closure Word Bank Skill Closure Identify what each set describes. Interpret the data contained in each set. Read each question carefully and determine which Venn Diagram states.
