Maths Key Skills Year 4
Number and Counting

I can count, order and compare numbers to 100,000 and understand the place value of the
digits.

I can round numbers to the nearest ten, hundreds and thousands.

I can round numbers to help me estimate and i can use this skill to help check my answers.

I understand that factors are whole numbers and that the smallest factor of a number is 1
and the greatest factor is the number itself.

I understand that the concept of factors and multiples are related e.g. 2 is a factor of 8 and
8 is a multiple of 2.
Multiplication and Division

I can use the formal written method to multiply 4 digit numbers by a 1 digit number.

I can use the formal written method to multiply 3 digit numbers by a 2 digit numbers.

I can use the formal written method to divide a 4 digit number by a 1 digit whole number.

I can use regrouping in multiplication and division.

I can apply concepts in the 4 operations to solve word problems up to 3 steps..

I know all my x tables up to 12 x12.
Measures

I can visualise and measure in compound units cm and m.

I can visualise and measure in compound units Km and m.

I can visualise and measure in compound units Kg and g.

I can visualise and measure in compound units Kg and g.

I can visualise and measure in compound units ml and l.

I can use all concepts in all four operations to solve 2 step word problems.
Tables and Line Graphs

I can present and interpret data in a table and in a line graph.
Fractions

I know a mixed number is made up of a whole number and a proper fraction e.g. 1¼

I know a proper fraction is part of a whole and is a number between 0 and 1.

I know that in an improper fraction the numerator is greater than or equal to the
denominator. The value of an improper fraction is greater than 1.

I can represent the same number with an improper fraction and a mixed number

I can convert two or more related fractions related fractions to fractions with the same
denominator and add or subtract them.
Angles

I know that an angle is the amount of turning.

I can accurately draw angles up to 180° and classify them as acute, obtuse or a right angle.

I know that a right angle (a quarter turn) is 90°, 2 right angles (a half turn) is 180°, 3 right
angles (a three-quarter turn) is 270° and 4 right angles (a complete turn) is 360°.

I know the directions on an 8 point copmpas: north (N), south (S), east (E), west (W),
north-east (NE),
north-west (NW), south-east (SE), south-west (SW).
Perpendicular and Parallel Lines

I can draw a pair of Perpendicular lines that meet or intersect at right angles.

I can accurately draw a pair of Parallel lines and know that they will never meet.

I know that the perpendicular distance between a pair of parallel lines is equal at every
point on the lines.
Squares and Rectangles

I know that a square is a four-sided shape in which all the sides are equal and all the
angles are right angles.

I know that a rectangle is a four-sided shape in which the opposite sides are equal and all
the angles are right angles.

I can describe the properties of squares (all the sides are equal and each angle = 90°) and
rectangles (opposite sides are equal and each angle = 90°).
Decimals

I understand that the first decimal place represents tenths and that 10 tenths = 1 one.

I understand that the second decimal place represents hundredths and that 10 hundredths
= 1 tenth.

I understand that the third decimal place represents thousandths and that 10 thousandths
= 1 hundredth.

I can use this knowledge to compare decimal numbers.

I can round decimals to the nearest tenth, hundredth and thousandth.

I know that decimals up to 3 decimal places are equivalent to fractions with denominators
10, 100 and 1000.

I can add and subtract, multiply and divide decimals and solve word problems involving
decimals.
Time

I can convert between minutes and seconds, using 1 minute = 60 seconds.

I can express time using 12 hour or 24 hour notation.
Statistics

I can make a bar graph with scales to present data.

I can read and interpret bar graphs.
Area and Perimeter

I know and can calculate the perimeter of a rectangle using the formula 2 × (Length +
Width) and a square, using the formula 4 × length of side.

I can calculate the area of a rectangle, using the formula of Length × Width (Ll x W) and a
square, using the formula of it is Side × Side (S x S).

I know that the distance of a composite shape is called the total distance around it.

I know that the area of a composite shape is the sum of all the areas of all the individual
rectangles and squares that make up the composite shape.

I can solve word problems involving area and perimeter.
Symmetry and Tessellations

I can identify a symmetrical shape because I can divide a shape into two equal parts with a
line of symmetry, recognising that the two parts fit exactly when folded along the line of
symmetry.

I recognise that a shape can be tessellated if any number of them can be fitted together to
cover a surface without any gaps or overlapping. If necessary, the shape can be rotated,
but not flipped over.
