Overview 
• What does effective mathematics teaching 
look like? 
• What types of knowledge does an effective 
teacher require? 
• How can we provide students with 
authentic mathematical opportunities? 
• What aspects of classroom practice should 
we focus on in order to maximise 
mathematical opportunities?
Connectionist, transmission and 
discovery beliefs 
Connectionist Transmission Discovery 
The use of methods of 
Primarily the ability to 
calculation which are 
perform standard 
both efficient and 
procedures or routines 
effective 
Finding the answer to a 
calculation by any 
method 
Confidence and ability in 
mental methods 
A heavy reliance on 
paper and pencil 
methods 
A heavy reliance on 
practical methods 
Pupil misunderstandings 
need to be recognised, 
made explicit and worked 
on 
Pupils’ 
misunderstandings are 
the result of ‘grasp’ what 
was being taught and 
need to be remedied by 
further reinforcement of 
the ‘correct’ method 
Pupils’ 
misunderstandings are 
the results of pupils not 
being ready to learn the 
ideas 
(Askew, et al., 1997)
Characteristics of effective 
numeracy teachers 
•Emphasise the importance of understanding mathematical 
concepts and the connections between these 
•Have high expectations that all children will engage seriously 
with mathematical ideas 
•Structure purposeful tasks that enable different possibilities, 
strategies and products to emerge 
•Probe and challenge children’s thinking and reasoning 
•Build on children’s mathematical ideas and strategies 
•Are confident in their own knowledge of mathematics at the 
level they are teaching 
(Groves et al., 2006)
Principles of practice 
•Make connections 
•Challenge all pupils 
•Teach for conceptual understanding 
•Purposeful discussion 
•Focus on mathematics 
•Convey and instill positive attitudes 
towards mathematics
Teaching actions 
• Choice of examples 
• Choice of tasks 
• Questioning 
• Use of representations 
• Modelling 
• Teachable moments

5 Practices 
• Anticipating 
• Monitoring 
• Selecting 
• Sequencing 
• Connecting 
(Smith & Stein, 2011)
Anticipating 
• Planning for ‘teachable moments’ 
• Knowing your subject and the difficulties 
students might encounter 
• Experience, research and reflection 
• Highlighting possible misconceptions in 
planning
Pre-planning 
• What do I need to know and understand 
before teaching this topic? 
• What are the likely difficulties or 
misconceptions students may have?
Measurement opportunities
Devise task 
• What are some activities or tasks you could 
undertake to explore ‘Mr Splash’?
• This is a photograph of Mr. Splash. He loves to 
have a bath in his pajamas. He seems to be a 
bit big for the bath! I wonder how tall he is? 
How could we find out?
• Does the tallest person have the longest feet? 
• Does the tallest person have the greatest hand span? 
• Are hand spans and foot lengths related? 
• Are boys taller than girls? 
• Draw a representation of Mr. Splash on the butcher paper. 
• Estimate the following and explain your estimates: 
– Mr. Splash’s height 
– Mr. Splash’s height compared to the tallest person in class 
– Mr. Splash’s height compared to the tallest person in your 
family 
– Mr. Splash’s height compared to the tallest person in the 
world 
• Explain whether you think Mr. Splash has the dimensions of a 
real person.
What teacher knowledge is required? 
• Content knowledge 
• Curriculum knowledge 
• PCK
Anticipating student responses 
Measurement considerations: 
• Selection of appropriate unit 
• Measuring accurately with units (e.g., lining 
up with no gaps, using the one unit) 
• Confusion with formal units and conversions 
(for older students)
In your groups, measure your 
heights, arm spans, hand spans and 
foot size (record these measures in 
the following table).

What do I need to know/consider about 
topic?
What do I need to know/consider about 
topic? 
• Length refers to the measurement of something from end to end 
• Sequence for teaching measurement 
• Children need to experience the usefulness of non-standard units 
• There are a number of principles to consider when asking 
students to measure with non-standard units: 
• The unit must not change – for example, we should select one 
type of informal unit, such as straws, to measure the length of the 
table, rather than a straw, pencil and rubber 
• The units must be placed end to end (when measuring length), 
with no gaps or overlapping units 
• The unit needs to be used in a uniform manner – i.e., if dominoes 
are being used to find the area of the top of a desk, then each 
domino needs to be placed in the same orientation in order to 
accurately represent the standard unit 
• There is a direct relationship between the size of the unit and the 
number required – i.e., the smaller the unit, the bigger the number 
and vice versa
What do I need to know about students’ 
learning of topic? 
• Possible misconceptions 
• Physical difficulties with measuring (e.g., physically 
lining up units, etc) 
• Individual considerations – how to differentiate the 
task
Estimating – a teachable moment

Sequencing
Consider: 
• What would be the advantages and 
disadvantages of doing this activity online as 
compared with using real materials in the 
classroom?
Capitalising on the ICT
Bridging 10
• Teacher: Great. OK. This is what we do when we 
bridge ten. We make one of the ten frames up into 
ten by moving the dots [shows two ten frames on the 
board next to each other, one with eight and one 
with seven counters or dots] Which would be the 
sensible one to move the dots in up here? 
• Student: Move from the yellow one to the purple one 
[ten frame] 
• Teacher: Would you do that Jim? Would you fill up 
the ten frame, the purple ten frame, with eight in it? 
Would you be able to put the dots on the other side? 
• [Jim moves the dots to the ten frame, and leaves a 
column of three dots and a column of two dots in the 
yellow frame]
• Teacher: Now can you arrange the other frame 
so that all the dots are in a straight line? 
• [Jim moves the dots so that they form a 
column of 5] 
• Teacher: Great, so what have we got? 
• Jim: Five and ten 
• Teacher: Which make? 
• Jim: Fifteen

Monitoring 
• Paying close attention to students’ 
mathematical thinking and solution strategies 
as they work on task 
• Can assist through creating a list of possible 
solutions before lesson (anticipating) 
• Questioning – more than observing

Connecting 
• Drawing connections between students’ 
solutions and the key mathematical ideas 
• Goal is to have student presentations build on 
one another to develop powerful 
mathematical ideas
More than ‘sharing’ 
Who did it a 
different way?
Factors influencing the planning and 
uptake of mathematical 
opportunities 
• Teacher knowledge Content 
knowledge, Pedagogical Content Knowledge (PCK) 
(Shulman, 1987) 
• Teacher beliefs What it is to be numerate 
pupil, how pupils learn to become numerate, and 
how best to teach pupils to become numerate
Choosing tasks to elicit 
mathematical opportunities 
• Connect naturally with what has been taught 
• Addresses a range of outcomes in the one task 
• Are time efficient and manageable 
• Allow all students to make a ‘start’ 
• Engage the learner 
• Provide a measure of choice or openness 
• Encourage students to disclose their own 
understanding of what they have learned 
• Are themselves worthwhile activities for students’ 
learning (Downton, et al., 2006, p. 9)

Place a number where you think it 
would fit…
Counting on Frank 
“I don’t mind having a bath – it 
gives me time to think. For 
example, I calculate it would take 
eleven hours and forty-five minutes 
to fill the entire bathroom with 
water. That’s with both taps 
running. It would take less time to 
empty, as long as no one opened 
the door!” 
(Clements, 1990, unpaged)
Is it accurate? 
“Going shopping with mum is a big event. She is 
lucky to have such an intelligent trolley-pusher. 
It takes forty-seven cans of dog food to 
fill one trolley, but only one to knock over one 
hundred and ten!”
• Does it really take 47 cans of dog food to fill 
one trolley? Even allowing for different sized 
trolleys and cans of dog food, this seems a 
gross under-estimation. In order to test this 
claim, a 12 year-old student, using real cans of 
dog food (680 gram; 23.94 ounce tins) found 
that it took approximately 47 cans of dog food 
just to fill the base of a shopping trolley, and 
that it would take closer to 216 cans to fill your 
average shopping trolley.
Anticipating mathematical 
opportunities 
• Confusion between length, area and volume 
(and capacity) 
• Conversion of units 
• Multiplication 
• Dimensions of tins 
• Consistency for comparison
