Seoul, South Korea | 17 December 2016

The other slides will come soon.

The apps I used today - I was writing mostly on Bamboo Paper.

This framework was introduced in 1992 and is still the one used today.
The research started in 1980 with the setting up of Curriculum Development Institute of Singapore under the leadership of Dr Kho Teck Hong.

It started with students performing at a low level.

Why problem solving?
Based on recommendations of Agenda for Action and Cockcroft Report and also predictions of what the economic needs.

Bangkok & Chiangmai, Thailand | 18.19 November, 2016

These are the apps I used.
Go to to see the links.

We looked at ways to help students develop visualization ability and ways to improve word problem solving.

The slides will be posted after the Chiangmai Session.

In the primary session, we looked at equivalent fraction and subtraction as well as word problems.
Using this as a case study, we derive strategies to develop visualization.

In the secondary session, we started by examining data on student achievement in mathematics. Lowstudent  achievement in Southeast Asian countries can be attributed to rote memorization, rote procedures and over-emphasis on computations and basic skills.

We looked at division by fractions, algebra, congruency and word problems on simultaneous equations and probably.

Honolulu, USA | 14.15 November 2016

3R Teacher Training website complied the list of apps I use.

We looked at the CPA Approach and Problem-Solving Approach and used two Stepping Stones lessons as case study. Grade 2 lesson on subtraction using number line was used to discuss how we support all learners especially struggling ones and Grade 5 lesson in conversion between measures of volume was used to discussed how we challenge advanced learners.

Along the way we looked at various things inspired by the questions raised by participants.

Hee are some of the slides

Farmington Public Schools

Singapore Math, as people call it, started as the government's initiative to improve mathematics learning of students who were not performing well. Hence, the provision of processing time, use of concrete materials and spiral approach are integral fundamentals of mathematics teaching and learning advocated by Singapore's curriculum.
 Case Study 1 - we saw the unfolding of an anchor task taken from MiF.
This is a summary of the discussion.

Refer to for links to these apps.

 Case Study 2 - we looked at an anchor task from MiF. We discussed target method, accessible method and advanced method.

Case Study 3 - Example from Grade 9 Singapore Textbook.

Helping students who need more time or more support....
