Welcome to St. Andrew’s Written Calculation

Evening

1st February 2010

Is this you?

‘My first thoughts of mathematics are fear, not being able to do it and feeling inferior.’

Adult attitude to maths

DfEE 1999 (10 years ago!)

‘Parents who are confident about Numeracy tend to have children who are also confident, and these children are ready to tackle and assimilate new ideas in a way that is impossible for children who feel uncertain about, or even fear, Numeracy.’

We all use Numeracy all day everyday!

• We look at the clock to tell the time before we get out of bed.

• We estimate how far it is to the floor!

• We know how many degrees to turn the tap so that we get enough water without getting soaked!

• We measure the cornflakes in our bowl so they don't spill over!

• Well you get the picture!

Number lines – Bead bar / number stick / individual number lines / Number ladders

Calculations

The aim is that children will always be able to recognise when calculations can be done ‘ in their heads’ and choose effective and efficient strategies to work out the answers.

Overview

Up to Year 3 the emphasis is on:o working mentally, o calculations recorded in horizontal number

sentenceso some jottings for more challenging numberso Practical activities

In Year 3-6 children will be gradually taught moreformal written methods of calculation butthey will still use mental methods and jottingswhere appropriate.

Workshops

• We’ve provided a carousel of workshops on all four calculation areas

• Each session will last approximately 20 minutes.• The bell will go after 15 minutes to warn

teachers that the session is about to finish.• Your first session is colour coded to your
