3. Students have learnt to add three one-digit numbers prior to this lesson. These are grade one students towards the end of the school year.
12. Number Bonds Number Bonds is emphasized prior to the learning of addition. Children are given, say, 5 unifix cubes and guided to see that 1 and 4 make 5, for example. Others may say that 3 and 2 make 5 or 4 and 1 make 5. Yet others may say that 5 and 0 make 5. Earlybird Kindergarten Mathematics (Standards Edition)
20. Addition Facts Addition Facts are given emphasis in the first six months of grade one. The children learn it in stages as the textbooks distinguished between Numbers to 10 and Numbers to 20. Count On and Count All are used in Numbers to 10. Earlybird Kindergarten Mathematics (Standards Edition)
21. Addition Facts &Number Sense While Count On and Count All are used in Numbers to 10, Make Ten is given emphasis in Numbers to 20. Photo: Princess Elizabeth Primary School
23. Professional Development for Singapore Math (Lower Grades) Day 2 Session 3 Emphasis on Visualization, Connections and Number Sense Photo: Princess Elizabeth Primary School
24. Communication Articulating one’s thoughts orally, at first, and in written forms using words, pictures, diagrams and symbols is important. Maris Stella High (Primary) School
25. Connections Looking for Patterns is introduced through exploration with Shapes. Subsequently, this is done using numbers – in a more abstract context. Photo: Princess Elizabeth Primary School MakeConnections to Generalize
27. Visualization Visualization is, among other things, the ability to manipulate visual images without the benefit of concrete objects. In the Japanese lessons, we saw children engaged in three-dimensional visualization (bean-container task) and two-dimensional visualization (pattern-block task). Photo: A Japanese Public School
28. “an excellent vehicle for the development and improvement of a person’s intellectual competence” This is the rationale stated in Singapore Mathematics curriculum document.

51. “A curriculum as it develops should revisit these basic ideas repeatedly, building upon them until the student has grasped the full formal apparatus that goes with them.” Jerome Bruner 1960 The Process of Education One feature of Singapore Math is the spiral approach.

56. “A curriculum as it develops should revisit these basic ideas repeatedly, building upon them until the student has grasped the full formal apparatus that goes with them.” Jerome Bruner 1960 The Process of Education Students have many opportunities to learn subtraction but each time building upon the strategies learnt previously.
67. Observe how this problem is different from the last one even though numbers used are the same.
