2. Content • Lesson study is enjoyable activity to develop children. • Mathematics is a key for KBS as well as English. • For developing mathematical thinking, teachers must improve teaching approach and schools must chose appropriate textbooks which are supported in Thailand. University of Tsukuba is Affiliated Member of SEAMEO

3. Lesson study is plan, do and see activities with various groups.InJapan, products of lesson study are shared through the books and Journals of lesson study. Their PCK is integrated and unified as teachers’ theories for teaching mathematics.. What is lesson study community? Teacher Subject M. Theory of Mathematics Children Participating Teachers Theories of Education Lesson study

6. Mathematics is Universal language. What language did they speak? We can develop creative and critical thinkers. However I am thinking in Thai. How difficult to think Mathematics in English They speak mathematics in English 2000 years ago, for training dialectic and reasoning by Greece, Mediterranean used to study mathematics.

7. Mathematical and Statistical Literacy on Knowledge B.S.Meletiou, M., and Lee, C. (2003),Isoda, Orlando(to appear) • Which of the two distributions you think has more variability? • Why do you think this? Now, you are in the classroom. Please make decision and riser your hands?

8. How do you read the distributions.Meletiou, M., and Lee, C. (2003),Isoda, Orlando(to appear) • Which of the two distributions you think has more variability? • Why do you think this? What is variability? Standard Deviation is the distance from the mean

9. Mathematical Thinking is the key for knowledge B.S.

10. How can we develop children’s mathematical thinking? • Knowing differences of Learned people (teachers) and Not yet learned children. Problem solving approach Four operations and calculations Addition Can you teach four operations by counting? Division Subtraction Multiplication Multiplication Subtraction Division Addition

11. How can we develop children’s mathematical thinking? • Knowing differences of Learned people (teachers) and Not yet learned children. • Problem Solving Approachis a key. (= Open Approach with well developed textbooks for developing children who learn mathematics by/for themselves) First Key: Teaching approach Second Key: Textbooks Division Multiplication Subtraction Addition

17. Problem S.A. Four phases for teaching approach: • Problem Posing : what we learned before. • Independent Solving: Patients, representation • Comparison and Discussion: Knowing and developing ideas • Summary and Integration: Value, Leaning how to Textbook for Problem Solving Approach(GakkoTosho)

18. Please complete the blackboard plan Why we have to compare? Task is given by teacher Various Solutions and Comparison <Fill in 2 > <Fill in 4 > How much Area? Let ‘s use! <Fill in 7> <Fill in 3 > <Fill in 5 > <Fill in 8> <Fill in 1 > <Fill in 6> Problem/atic is posed from children, if possible Resume the result of comparison and selection based on generality Why we need problematic?

19. Conclusion • Mathematics is a key for KBS as well as English. • Lesson study is enjoyable activity to develop children. • For developing mathematical thinking, teachers must improve teaching approach and schools must chose appropriate textbooks which are supported in Thailand. Lets, learn together through lesson study!
