Session 2

Making Good Progress in Mathematics

Calculation


Objectives

Objectives

  • To examine the characteristics of pupils making slow progress in mathematics.

  • To identify and discuss the obstacles to progress in calculation.

  • To consider implications for managing mathematics in school.


Pupil characteristics

Pupil characteristics

  • Often girls

  • Viewed mathematics as either right or wrong

  • Judged how good they were by the number of ticks or crosses

  • Didn’t like answering questions – saw this as a risk

  • Tended to work on their own – when they worked with others this was to align answers

  • Their work was neat


Obstacles to progress

Obstacles to progress

In number and calculation, pupils:

  • Have difficulty identifying related facts from known facts.

  • Were reluctant to use mental calculation skills.

  • Used formal written methods in preference to mental methods as they believed formal methods were better.

  • Relied on one fixed method to get a correct answer.

  • Lacked images and models to help with visualising mathematics.


Other significant findings

Other significant findings

Pupils:

  • Lacked opportunities for talk during mathematics lessons with their teacher, teaching assistant and peers.

  • Experienced a low level of challenge and tended to work within their comfort zone.

  • Developed a low appetite for risk-taking

    Teachers:

  • Some believed that children would be more self-confident if they always got the right answers, but this often led to routine and low-level work.


What do pupils need

What do pupils need?

  • Structured and guided opportunities to develop a range of mental calculation strategies.

  • Experience of different ways to approach a problem or to do a calculation and to be able to compare their methods and ideas with others.

  • Support and modelling from adults to help them to work on more open approaches, to decide how and what to record.


Issues related facts

Issues – related facts

  • Children had difficulty finding related facts from known facts.

  • Children viewed multiplication facts as unrelated facts they needed to memorise, and found this difficult.


Dealing with the issues related facts

Dealing with the issues – related facts


Issues lack of strategies

Issues – lack of strategies

  • Sustained teaching and learning of strategies and use of models and images to support

  • Frequent use and application of known facts to derive new ones

  • Understanding by teacher and pupil of the building blocks which are needed for calculation – e.g., place value, partitioning, structure of the number system

  • Frequent revisiting of strategies – discussion and evaluation of effectiveness and efficiency


Issues lack of strategies1

Issues – lack of strategies

  • 8

  • 1917

  • 48

  • 149

Subtract 50 to make

147 then add 2 back

to make 149

Which

Method..?

197 - 48

  • 52 90 7

  • __________

  • 100 190 197

  • 52 + 90 + 7 = 149

Add 2 to 48, to make 50

Then add 50 to make 100.

Then add 90 to make 190.

Then add 7 to get 197.

2+50+90+7 = 149

Take 40 off to make 157

Then 8 off to make 149


Which strategy

Which strategy…?

67 + 7 +20

154 x 3

2008 – 1996

168 ÷ 4

345 – 257

5.0 – 1.54


Issues use of formal methods

Issues – use of formal methods

  • Are formal methods the first resort for children in calculations using larger numbers?

  • Do children stop using jottings/number lines once they have been introduced to formal methods?

  • Do children make choices about the methods of calculation they use?


Identifying the issues

Identifying the issues

  • Lesson observations

  • Book scrutinies

  • Pupil conferences

  • Planning

  • Teacher audits

  • Data analysis


Key outcomes

Key Outcomes

  • Every child, unless there is a barrier to cognition and learning, is entitled to reach national expectations or better at the end of each key stage.

  • Every child should make good progress through a key stage.

  • All children are in a school/setting that enables this to happen.

  • Every child has the right to teaching and learning which enables them to reach the national expectations.

  • Every child expects and is expected to be involved in the process
