Year 3
The mathematics learnt in Year 3 is fundamental to building understanding in more advanced concepts. Key areas for the year are:
mental and written calculations
multiplication tables knowledge
understanding of, and calculating with fractions
the place value of decimals
reading accurately, and converting between, units of time
understanding the concept of angles
Below are the expectations of the Walhampton mathematics curriculum for Year 3. These form the basis of the 'expected' attainment grade. It is anticipated that some children will be able to exceed these objectives and explore the topics in more depth.
Number and Place Value Skills
Children will learn to:
identify and represent numbers using different representations
read and write numbers up to 1000 in numerals and in words
recognise the place value of each digit in a three-digit number
compare and order numbers to 1000
round numbers to the nearest 10, 100 and 1000
solve problems and practical problems involving the above ideas.
Calculation
Children will learn to:
count in multiples of 4, 8, 50 and 100
find 10 or 100 more or less than a given number
estimate the answer to a calculation and use inverse operations to check answers
add and subtract numbers mentally, including:
a three-digit number and ones
a three-digit number and tens
a three-digit number and hundreds
add and subtract numbers with up to three digits, using formal written methods of columnar addition and subtraction
solve problems including missing number problems, using number facts, place value, and more complex addition and subtraction
recall and use multiplication and division facts for the 3, 4 and 8 multiplication tables
write and calculate mathematical statements for multiplication and division using the multiplication tables that they know, including for two-digit numbers times one-digit numbers, using mental and progressing to formal written methods
solve problems involving missing number problems, involving multiplication and division, including positive integer scaling problems and correspondence problems in which n objects are connected to m objects.
Fractions
Children will learn to:
count up and down in tenths; recognise that tenths arise from dividing an object into ten equal parts and in dividing one-digit numbers or quantities by ten.
recognise, find and write fractions as a discrete set of objects: unit fractions and non-unit fractions non-unit fractions with small denominators
recognise and use fractions as numbers: unit fractions and non-unit fractions non-unit fractions with small denominators
recognise and show, using diagrams, equivalent fractions with small denominators
compare and order unit fractions, and fractions with the same denominators
add and subtract fractions with the same denominator within one whole
solve problems that involve all of the above.
Algebra
Children will learn to:
solve problems involving missing number problems.
Measurement
Children will learn to:
measure, compare, add and subtract:
lengths (m/cm/mm);
mass (kg/g);
volume/capacity (l/ml)
add and subtract amounts of money to give change, using both pounds and pence in practical contexts
tell and write the time from an analogue clock, including using Roman numerals from I to XII, and 12-hour and 24-hour clocks
estimate and read time with increasing accuracy to the nearest minute; record and compare time in terms of seconds, minutes and hours, use vocabulary such as o'clock, a.m./p.m., morning, afternoon, noon and midnight
know the number of seconds in a minute and the number of days in each month, year and leap year
compare durations of events.
Geometry
Children will learn to:
measure the perimeter of simple 2-D shapes
draw 2-D shapes
make 3-D shapes using modelling materials; recognise 3-D shapes in different orientations and describe them
recognise angles as a property of shape or a desciption of a turn
identify right angles, recognise that two right angles make a half-turn, three make three quarters of a turn and four a complete turn; identify whether angles are greater than or less than a right angle
identify horizontal and vertical lines and pairs of perpendicular and parallel lines
Statistics
Children will learn to:
interpret and present data using bar charts, pictograms and tables
solve one-step and two-step questions using information presented in scaled bar charts and pictograms and tables.
