- 5. Math Facts about Bahrain Bahrain is actually an archipelago of 33 islands. The largest, on which many people live, is 55km long by 18km wide and areas such as Sitra and Muharraq are actually separate islands. Bahrain’s flag used to be the largest flag in the world, setting a Guinness world record in 2004 at 169.5m long and 97.1m wide. The five red points signify the five pillars of Islam. The oldest known Bahraini flags were plain red. In 1820, the island signed a treaty with the UK and a white stripe was added to the flag to indicate the truce. In 1932, a serrated edge was added to distinguish Bahrain’s flag from those of its neighbours. The flag originally had 28 white points, but this was reduced to eight in 1972 and five in 2002.

- 6. More Math Connections in Bahrain Bahrain World Trade Centre is the first skyscraper in the world to integrate wind turbines into its design. Each turbine is 29m in diameter and their capacity is 675kw of wind power production. The 240m-tall tower has won several international awards including the LEAF (Leading European Architects’ Forum) award for best use of technology in a large scheme. The British School of Bahrain holds the world record for the largest simultaneous coin toss. As part of World Maths Day in 2010, 1,117 staff and students took part in the toss which made it into the Guinness Book of Records.
- 7. Why use manipulatives? Concrete. The “doing” stage using concrete objects to model problems Representational. The “seeing” stage using representations of the objects to model problems Abstract. The “symbolic” stage using abstract symbols to model problems
- 8. Solving Basic Facts: Partner Work The Student’s Hat Work on the problems, using manipulatives to concretely model the solution. The Teacher’s Hat Consider student abilities: Direct modeling, counting, derived facts, recall PROBLEMS 5 + 7 = ? 12 – 5 = ? 4 + ? = 11 5 x 7 = ? 56 8 = ?
- 9. PROBLEM DIRECT MODELING COUNTING DERIVED FACTS RECALL 5 + 7 = ? Join Result Unknown Makes a set of 5 counters and a set of 7 counters. Pushes the two sets together and counts all the counters. Counts “5 [pause], 6, 7, 8, 9, 10, 11, 12,” extending a finger with each count. “The answer is 12” [The counting sequence may also begin with the larger number] “Take 1 from the 7 and give it to the 5. That makes 6 + 6, and that’s 12.” 5 plus 7 is 12. 12 – 5 = ? Separate Result Unknown Makes a set of 12 counters and removes 5 of them. Then counts the remaining counters. Counts back “12, 11, 10, 9, 8 [pause], 7. It’s 7.” Uses fingers to keep track of the numbers of steps in the counting sequence. “12 take away 2 is 10, and take away 3 more is 7.” 12 take away 5 is 7. 4 + ? = 11 Join Change Unknown Makes a set of 4 counters. Makes a second set of counters, counting “5, 6, 7, 8, 9, 10, 11,” until there is a total of 11 counters. Counts the 7 counters in the second set. Counts “4 [pause], 5, 6, 7, 8, 9, 10, 11,” extending a finger with each count. Counts the 7 extended fingers. “It’s 7.” “4 + 6 is 10 and 1 more is 11. So it’s 7.” 4 and 7 make 11. 5 x 7 = ? Makes 5 groups of 7 counters and counts them all. 7, 14, 21, 28, 35 or 5, 10, 15, 20, 25, 30, 35 5 times 5 is 25 and 10 more is 35. 5 times 7 is 35. 56 8 = ? Counts out 56 counters. Pulls out groups of 8 until 7 groups are made. 8, 16, 24, 32, 40, 48, 56 8 times 8 is 64. 8 less is 56. So that’s 7. 8 x 7 is 56.

- 10. Create a Mini-Lesson Components for the Mini-Lesson • at least one math manipulative • CCSS-M (math standard) • Standard(s) for Mathematical Practice • Interdisciplinary connection/s • Independent/pair/small group/whole group? • How will students communicate mathematically? Manipulatives for Consideration • Counters • Connecting cubes • Base ten counters • Number line • Random number generator (number cubes) • Spinners
- 11. 1. Make sense of problems and persevere in solving them. 2. Reason abstractly and quantitatively. 3. Construct viable arguments and critique the reasoning of others. 4. Model with mathematics. 5. Use appropriate tools strategically. 6. Attend to precision. 7. Look for and make use of structure. 8. Look for and express regularity in repeated reasoning. Learning through the Standards for Mathematical Practice

- 13. What are some of the biggest challenges students face with fractions?
- 14. In One Minute… • write down everything that comes to mind when you think about or see 5 8
- 15. Now, in one minute… • write down everything that comes to mind when you think about or see 9
- 16. Compare Your Responses • What similarities do you see? • What differences do you see? • Any surprises or insights?
- 17. The Progression of Fractions NF Standards, Grades 3-5
- 18. Prior knowledge through the lens of geometry
- 19. Develop understanding of fractions • 3.NF1 Understand a fraction 1/b as a quantity formed by 1 part when a whole is portioned into b equal parts: understand a fraction a/b as the quantity formed by a parts of size 1/b.
- 20. TASK: Locate 1 on the number line. Label the point. Be exact as possible. While it is not necessary to name all of the intervals on the number line, many students may do so .

- 22. Other Helpful Considerations for Understanding Fractions • Fraction Basic Vocabulary (denominator) • 2 is pronounced “half” • 3 is pronounced “third” • 4 is pronounced “fourth” (or “quarter”) • 5 is pronounced “fifth” • 6 is pronounced “sixth” • 7 is pronounced “seventh” • 8 is pronounced “eighth” • 9 is pronounced “ninth” • 10 is pronounced “tenth,” and so on. • Where do we see and use fractions in our daily lives? • Support Strategy: The use of pictures provides students with realia for understanding fractions • Wholes vs. Holes • Use visual images that support all learners for understanding this concept.
- 23. Equivalent Fractions • The meaning of fraction equivalence • The equivalence of whole numbers and fractions • Explaining fraction equivalence in general
- 24. Adjectives vs. Nouns (Adapted from Kathy Richardson, NCTM 2008) • Young children initially consider numbers as adjectives or descriptors • 9 bears • 6 cookies • 20 students • Eventually, they come to understand numbers as nouns or concepts 9 is … • half of 18, • It is 1 less than 10, • It is 4.5 doubled, • It is 3 squared, • It is the square root of 81, • ………..?
- 25. Adjectives vs. nouns (continued) • Students need opportunities to transition from considering fractions as adjectives 1/2 of a pizza 3/4 of an hour 2/3 of a cup • to considering them as nouns 5/8 is… a little more than 1/2, but less than 1 It is 3/8 less than 1 It is equivalent to 10/16 It is twice 5/16 It is half of 1¼ ……………?
