# Year Three Mathematics

Numbers & the number system

• Count from 0 in multiples of 4, 8, 50 and 100; find 10 or 100 more or less than a given number.

• Recognise the place value of each digit in a three-digit number (hundreds, tens, ones).

• Compare and order numbers up to 1000 .

• Identify, represent and estimate numbers using different representations.

• Read and write numbers up to 1000 in numerals and in words.

• Solve number problems and practical problems involving these ideas.

• 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 & subtract numbers with up to three digits, using formal written methods of columnar + and –

• Solve problems, including missing number problems, using number facts, place value & more complex + &

Calculation - multiplication & division

• Recall & use x and ÷ facts for the 3, 4 and 8 tables.

• · Write and calculate statements for x and ÷ using tables they know, including for TU x U using mental and progressing to formal written methods.

• Solve problems, including missing number problems, involving multiplication and division, including integer scaling problems and correspondence problems in which n objects are connected to m objects.

Calculation - Fractions, Decimals & Percentages

• Count up and down in tenths; recognise that tenths arise from dividing an object into 10 equal parts and in dividing one-digit numbers or quantities by 10.

• Recognise, find and write fractions of a discrete set of objects: unit fractions and non-unit fractions with small denominators.

• Recognise and use fractions as numbers: unit fractions & non-unit fractions with small denominators.

• Recognise and show, using diagrams, equivalent fractions with small denominators.

• Add and subtract fractions with the same denominator within one whole [ e.g. 5/7 + 1/= 6/7 ]

• Compare and order unit fractions, and fractions with the same denominators.

• Solve problems that involve all of the above.

Measures

• Measure, compare, add and subtract: lengths (m/cm/mm); mass (kg/g); volume/capacity (l/ml)

• Measure the perimeter of simple 2-D shapes

• Add and subtract amounts of money to give change, using both £ and p 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, [for example to calculate the time taken by particular events or tasks.]

Shape & Space

• Draw 2-D shapes and 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 description 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

• Interpret and present data using bar charts, pictograms and tables

• Solve one and two step questions [For example: “How many more?”  and  “How many fewer?”]… using information presented in scaled bar charts and pictograms and tables.
