Core Belief
All students can ______
Learning Issues
Learning gaps, language,
motivation and ________
learn
retention
-
Making the Case Focus on number sense!
Research indicates that early number sense predicts school success more than other
measures of cognition like verbal, spatial or
memory skills or reading ability.
Jordoan, Kaplan, Locuniak, and Ramineni,
2007
Number sense:
Ability to use numbers, appreciation of numbers
(knowledgeable about what a number means) and
number relationship
-
Factual Fluency
Ability to recall the answers to basic math facts
automatically and without hesitation.
-
Achieve mastery in
Primary 1
Basic addition and subtraction facts within 20
Primary 2
Multiplication and division facts (within multiplication tables of 2, 3, 4, 5 & 10)
Primary 3
Multiplication and division facts (within multiplication tables of 6, 7, 8 & 9)
Factual Fluency Targets
Factual Fluency makes it easier
to learn Math
-
Developmental Nature of Basic Fact Mastery
Counting Reasoning Mastery
-
Phase 1:
Counting strategies-
using concrete objects
Counting up
Counting down
Example includes:
5 + 1 = ?
5 + 2 = ?
5 1 = ?
5 2 = ?
Counting Strategies
-
Phase 2:
Reasoning Strategy:
using known information to logically determine an unknown combination
4 + 7 =?
5 x 8 is 40
Reasoning Strategy
-
Phase 3:
Producing answers efficiently
- Use strategy learnt to provide the correct answer within 5 seconds
e.g. 4 + 7 = 11
Mastery
-
Knowing Facts from Memory-
Passive Storage View
Thinking that students will learn
their facts if they just practise
enough
What does this mean
Learning isolated number facts
Memorizing many facts
Keep practising to memorize
-
Effects of not knowing number facts fluently
Lack of basic fact automaticity has been associated with
Limited participation in math class discussions
Unsuccessful problem solving
Weak development of skills in multiple-digit addition and subtraction, long division and fractions
Misapplication of facts and providing unreasonable answers
Inflexible thinking skills
-
Learning Facts: Addition
Addition
-
How many strategies?
Addition
Count On
Use Doubles
Bridge to 10
-
6 x 5 = 30
30 + 6 + 6 = 42
(Connection of Ideas)
Significance (Meaning)
Multiplication as
repeated addition
Commutative
Property of
multiplication:
the two
numbers can
be multiplied in
either order.
(equivalence)
Spiral nature of Learning Multiplication
-
Concrete-Pictorial-Abstract Approach
-
Multiple Representations
4 x 6 = ?
4 groups
of 6 cubes
4 rows
of 6 boxes
4 pots of 6 flowers each
-
More examples of Multiple Representations
13 x 3 = ?
(3 groups of 13 ones)
(3 rows of 13 boxes)
Place Value
Sharing Tip:
1. String 10 buttons together to represent 1 ten.
2. Egg cartons which are available in 10s or 30s may also be used.
-
Give Examples and Non examples
-
Communicate, Reason and Reflect
form relationships
make connections
integrate learning
Probe understanding and stimulate thinking
How do you know?
Why is it so?,
Explain how you..
Can you give me an example?
Promote Reasoning 16 x 5 = ?
-
Scaffold Learning
Mary has five stickers. Ali has three times as many stickers as Mary.
Pictorial

How to teach Multiplication using cubes
REGROUP
the ones
23 x 4 = ?
4 groups of 23 (use cubes)
9 tens and 2 ones

Ways to Connect Conceptual Knowledge with
Procedure Knowledge
23 x 4 = ?
3 x 4 = ?
20 x 4 = ? ?
