Bruner CPA Approach
2,476 x 3
Greenville Elementary School, New York
The concrete materials show 2,476 = 2,000 + 400 + 70 + 6
Greenville Elementary School, New York
The concrete materials make students do partial multiplication
The concrete materials allow regrouping (18 = 10 + 8)
Using Concrete Materials
They are used in tandem with
pictorial and symbolic
representations, not one after
another.
Avoid jargon and employ more
‘revoicing’ i.e. students’
language in early stages of
learning
Concrete material embodies the
essential ideas

Advanced Learners
• Make a story
• Give another way. Give an
original way.
• Explain to a friend. Write an
explanation. Draw a diagram
to show.
• My friend has an idea. What
do you think of it?
Singapore Math adopts
enrichment model and not
acceleration model.
