National Singapore Math Summer Institute at Westminster Colorado Day 2

This is my presentation on Day 2 which is to show how to use Singapore Math to implement Common Core State Standards.

Skemp's idea of relational understanding and instrumental understanding reminds us that there is no dichotomy between procedural and conceptual understanding.

We referred to three big ideas today - Generalization, Visualization and Number Sense.

Three ways to subtract (1) subtracting 3 from 4 and subtracting 7/12 from 9/12 (2) subtracting 3 from 3 and 7/12 from 1 (3) having everything as twelfths

Share 2 pizzas between 3 friends (1) 6 thirds shared by 3 (2) 6 fourths and 6 twelfths shared by 3

Students learn procedure alongside the concept.

Shinglee Publishers Mathematics Textbook Launch

The latest edition of the secondary mathematics textbook for Singapore schools was launched yesterday. I am proud to be the consultant to this textbook series that has been around since the 1980's. It is one of the two textbook series approved for use in secondary schools for the latest syllabus for the Express course. For the first time, Shinglee also published one of the two textbooks for the Normal Academic course.

This is the presentation made at the book launch which doubled up as a professional development afternoon for the teachers.
