Singapore Math Overview with Common Core Connections Richard Bisk Professor Mathematics Department Worcester State University [email protected] Dr. Richard Bisk - [email protected] Warnings about the presenter He talks ahead of his slides. He may have too many slide; so he might skip over a few. They will be posted on the website. He will talk about the Common Core tomorrow too. Dr. Richard Bisk - [email protected] Singapore Books in the U.S. Three versions, all published by Marshall Cavendish Education: a. Primary Math: US Edition California Standards Edition Common Core Edition c. Math In Focus – HMH Adaptation of “My Pals are Here” Dr. Richard Bisk - [email protected] My Career • Trained as a mathematician. • Worked entirely at teaching colleges and universities. • Many students (25-50%) unprepared for college level math courses. • Few (<10%) prepared for calculus. Dr. Richard Bisk - [email protected] College Readiness Why do many students come to higher education with significant mathematical weaknesses that limit their career options? Weak foundation that goes back to elementary and middle school. Led to an interest in working with K-8 teachers and their students. Content based PD is my passion. Use books from Singapore because the math is so clear and coherent. Why the interest in Singapore? a. TIMSS Studies - 1995, 1999, 2003, and 2007, 2011. b. National Math Panel Report - 2008 c. Common Core State Standards Initiative (CCSSI) - 2010 Dr. Richard Bisk - [email protected] TIMSS – 2011 Grade 4 Grade 8 Singapore 606 South Korea 613 South Korea 605 Singapore 611 Hong Kong 602 Taiwan 609 Taiwan 591 Hong Kong 586 Japan 585 Japan 570 InstructionNorthern Ireland in Singapore562 is Russiain English 539 Belgium 549 Israel 516 Finland 545 Finland 514 England 542 United States 509 Russia 542 England 507 International 500 International 500 Dr. Richard Bisk - [email protected] National Math Panel • Even in elementary school, the U.S. is not among the world leaders; only 7% of U.S. fourth-graders scored at the advanced level in TIMSS, compared to 38% of fourth-graders in Singapore, a world leader in mathematics achievement. (page 4) • In elementary school textbooks in the United States, easier arithmetic problems are presented far more frequently than harder problems. The opposite is the case in countries with higher mathematics achievement, such as Singapore. (page 26) Dr. Richard Bisk - [email protected] Common Core Standards The composite standards [of Hong Kong, Korea and Singapore] have a number of features that can inform an international benchmarking process for the development of K–6 mathematics standards in the US. (Second paragraph of introduction- quoted from: Ginsburg, Leinwand and Decker, 2009) Dr. Richard Bisk - [email protected] Common Core Standards In general, the US textbooks do a much worse job than the Singapore textbooks in clarifying the mathematical concepts that students must learn. Because the mathematics concepts in [U.S.] textbooks are often weak, the presentation becomes more mechanical than is ideal. We looked at both traditional and non-traditional textbooks used in the US and found this conceptual weakness in both.

Pictorial: ││││││││ Abstract: 8 Abstraction • Gives mathematics its power. • But abstraction without understanding?? • Leads to confusion. Dr. Richard Bisk - [email protected] Look for and make use of structure MP7: “Mathematically proficient students look closely to discern a pattern or structure … students will see 7 × 8 equals the well remembered 7 × 5 + 7 × 3, in preparation for learning about the distributive property.” Dr. Richard Bisk - [email protected] • CCSS.Math.Content.3.OA.B.5 …Knowing that 8 × 5 = 40 and 8 × 2 = 16, one can find 8 × 7 as 8 × (5 + 2) = (8 × 5) + (8 × 2) = 40 + 16 = 56. Dr. Richard Bisk - [email protected] Dr. Richard Bisk - [email protected] Dr. Richard Bisk - [email protected] Dr. Richard Bisk - [email protected] Grade 1 – Common Core • CCSS.Math.Content.1.OA.B.4 Understand subtraction as an unknown-addend problem. For example, subtract 10 – 8 by finding the number that makes 10 when added to 8. • CCSS.Math.Content.1.OA.C.6 Add and subtract within 20, demonstrating fluency for addition and subtraction within 10. Use strategies such as making ten ( 8 + 6 = 8 + 2 + 4 = 10 + 4 = 14); Dr. Richard Bisk - [email protected] Grade 2 – Common Core • CCSS.Math.Content.2.OA.B.2 Fluently add and subtract within 20 using mental strategies.2 By end of Grade 2, know from memory all sums of two one-digit numbers.

Dr. Richard Bisk - [email protected] Dr. Richard Bisk - [email protected] This reinforces: “Understand subtraction as an unknown-addend problem. “ Dr. Richard Bisk - [email protected] Dr. Richard Bisk - [email protected] Grade 3 – Common Core 3.OA.2. Interpret whole-number quotients of whole numbers, e.g., interpret 56 ÷ 8 as the number of objects in each share when 56 objects are partitioned equally into 8 shares, or as a number of shares when 56 objects are partitioned into equal shares of 8 objects each. 3.OA.6. Understand division as an unknown-factor problem. For example, find 32 ÷ 8 by finding the number that makes 32 when multiplied by 8. Dr. Richard Bisk - [email protected] Number of Objects Dr. Richard Bisk - [email protected] Number of Shares Dr. Richard Bisk - [email protected] Common Core – Grade 4 Use place value understanding and properties of operations to perform multi- digit arithmetic. • 4.NBT.4.
