In Mathematics during Year 1, the children will learn many new skills including:


Number – number and place value

  • count to and across 100, forwards and backwards, beginning with 0 or 1, or from any given number.
  • count, read and write numbers to 100 in numerals; count in multiples of twos, fives and tens.
  • given a number, identify one more and one less.
  • identify and represent numbers using objects and pictorial representations including the number line, and use the language of: equal to, more than, less than (fewer), most, least.
  • read and write numbers from 1 to 20 in numerals and words.

Number – addition and subtraction

  • read, write and interpret mathematical statements involving addition (+), subtraction (–) and equals (=) signs.
  • represent and use number bonds and related subtraction facts within 20.
  • add and subtract one-digit and two-digit numbers to 20, including zero.
  • solve one-step problems that involve addition and subtraction, using concrete objects and pictorial representations, and missing number problems such as 7 = – 9.

Number – multiplication and division

  • solve one-step problems involving multiplication and division, by calculating the answer using concrete objects, pictorial representations and arrays with the support of the teacher.

Number – fractions

  • recognise, find and name a half as one of two equal parts of an object, shape or quantity.
  • recognise, find and name a quarter as one of four equal parts of an object, shape or quantity.


Compare, describe and solve practical problems for:

  • lengths and heights [for example, long/short, longer/shorter, tall/short, double/half].
  • mass/weight [for example, heavy/light, heavier than, lighter than].
  • capacity and volume [for example, full/empty, more than, less than, half, half full, quarter].
  • time [for example, quicker, slower, earlier, later].

measure and begin to record the following:

  • lengths and heights.
  • mass/weight.
  • capacity and volume.
  • time (hours, minutes, seconds).
  • recognise and know the value of different denominations of coins and notes.
  • sequence events in chronological order using language [for example, before and after, next, first, today, yesterday, tomorrow, morning, afternoon and evening].
  • recognise and use language relating to dates, including days of the week, weeks, months and years.
  • tell the time to the hour.

Geometry – properties of shape

Recognise and name common 2-D and 3-D shapes, including:

  • 2-D shapes [for example, rectangles (including squares), circles and triangles].
  • 3-D shapes [for example, cuboids (including cubes), pyramids and spheres].

Geometry – position and direction

  • describe position, direction and movement, including whole, half, quarter and three-quarter turns.
