10 Steps to Success - Year 3 - Maths

The main focus of mathematics in Year 3 is to ensure that pupils become increasingly fluent with whole numbers and the four operations of addition, subtraction, multiplication and division with numbers up to the thousands. This will ensure that pupils develop efficient written and mental methods and perform calculations accurately with increasingly larger whole numbers. Pupils will develop their ability to solve a range of problems, including simple fractions and decimals. Pupils develop their mathematical reasoning so they can solve problems and analyse shapes by their properties. By the end of Year 3 pupils should have a firm grasp of their 3, 4 and 8 times tables.

We’ve broken the year’s key learning into 10 skills. If children can master these in year 3, they will make a flying start to year 4. They won’t necessarily be mastered in order.

Skill 1

Times-tables: Apply 3, 4 and 8 times tables, including associated division facts (e.g. 3 x 8 = 24 so 24 ÷ 8 = 3).    





Skill  2

Addition: Apply number bonds and standard Column Addition methods to HTU, in and out of context (including money and measures), and to solve missing number problems.    







Skill  3

Subtraction: Apply number bonds and standard Column Subtraction to HTU in and out of context (including money and measures), and to solve missing number problems.    







Skill  4

Multiplication: Apply multiplication knowledge using the Grid Method TUxU in and out of context (including money and measures).    






Skill  5

Division: Apply written methods for division using chunking up to TU ÷ U, with and without remainders in and out of context (including money and measures).    







Skill  6

Fractions and Decimals: Calculate and compare unit fractions of quantities e.g. finding ⅓ of 24. Understand that decimals (tenths) are also used to show fractions of a whole. Order tenths on a numberline.    







Skill  7

Balance and inverses: Apply understanding of the mathematical symbols <, > and = in balance and missing number problems (e.g. 3 x __ = 10 + 5).    








Skill  8

Checking answers: Check answers using written methods, using the inverse operation (e.g. 100 – 63 = 37 so 37 + 63 = 100).    






Skill  9

Shape and Space: Describe and measure the perimeter of 2D shapes; recognise 3D shapes; recognise right angles and turns; identify horizontal, vertical, perpendicular and parallel lines.    








Skill 10

Times and Measures: Tell the time in 12 and 24 hour clock (using an analogue clock, including Roman numerals) to the nearest minute; know the number of days in each month, year and leap year.
