This page is a reprint of the material used for the math's
lesson on November 23rd 2003 for Years 3 and 4 parents .
Trinity St Mary’s follows the National Numeracy Strategy for the teaching of mathematics. The Strategy details mathematical procedures for each year group and there is a systematic progression in the teaching of knowledge, skills and understanding as your child moves through primary school.
One of the purposes of primary school mathematics is to introduce the child to a variety of different computational methods. This is to ensure that children of all abilities have, at their fingertips, ways of “working things out” that they are comfortable with.
Some of these ways may be very different to those that we adults were taught at school, thus adults are sometimes unsure how to help their children.
There are no right or wrong methods for working things out – some ways are quicker than others and there are preferred methods. It is hoped that eventually the child opts for those, but most importantly, they need to find a method that works for them.
I hope the following will be helpful and of interest to you.

What your child will learn in Years 3 and 4
Year 3
Read, write and order whole numbers to at least 1000; know what each digit represent
Count on or back in tens or hundreds from any two or three digit number
Recognise unit fractions such as ½, ¹/3, ¼, ¹/5, ¹/10, and use them to find fractions of shapes and numbers
Know by heart all addition and subtraction facts to 20
Add and subtract mentally a ‘near multiple of 10’ to or from a 2 digit number
Know by heart facts for the 2, 5 and 10 times tables
Understand division and recognise that it is the inverse of multiplication
Use units of time and know the relationships between them (second, minute, hour, day, week, month, year)
Understand and use £.p notation
Choose and use appropriate operations (including multiplication and division) to solve word problems, explaining methods and reasoning
Identify right angles
Identify lines of symmetry in simple shapes and recognise shapes with no lines of symmetry
Solve a given problem by organising and interpreting numerical data in simple lists, tables and graphs.
Year 4
Use symbols correctly, including less than (<), greater than (>), equals (=).
Round any positive integer less than 1000 to the nearest 10 or 100
Recognise simple fractions that are several parts of a whole, and mixed numbers, recognise the equivalence of simple fractions.
Use known number facts and place value to add or subtract mentally, including any pair of two-digit whole numbers.
Carry out column addition and subtraction of two integers less than 1000, and column addition of more than two such integers.
Know by heart facts for the 2, 3, 4, 5 and 10 multiplication tables .
Derive quickly division facts corresponding to the 2, 3, 4, 5 and 10 multiplication tables.
Find remainders after division.
Know and use the relationships between familiar units of mass, capacity
Classify polygons, using criteria such as number of right angles, whether or not they are regular, symmetry properties
Choose and use appropriate number operations and ways of calculating (mental, mental with jottings, pencil and paper) to solve problems
Vocabulary for the 4 rules of number
It is important that children know all the alternative words associated with addition, subtraction, multiplication and division. This is particularly necessary when they are solving everyday problems.
Addition:
More than, add, sum, total, altogether, increase
Subtraction:
Take away, subtract, how much less, how many are left, difference between, how much more, decrease
Multiplication:
Times, multiply, product, multiply by
Division:
Share, group, divide, divided by, divided into, divisible by, remainder
