# Year 4 Maths

It is our aim that all children in Year 4 meet the following expectations:

**Number**

- Count in multiples of 6, 7, 9 and 1,000.
- Find 1,000 more or less of a given number.
- Count backwards through 0 to include negative numbers.
- Know the value of each digit in a four digit number (thousand, hundreds, tens and ones).
- Order and compare numbers beyond 1,000.
- Round numbers to the nearest 10, 100 or. 1,000.
- Solve problems involving the above using increasingly larger numbers.
- Know the Roman numerals from 1 - 100 (1 - C).

**Calculations**

- Add and subtract using a formal column method for addition and subtraction for four digit numbers and then checking answers using the inverse operation.
- Solving two step problems involving addition and subtraction.
- Multiply two and three digit numbers by a single digit using a shirt multiplication formal written method.
- Use a shirt division formal written method with exact answers.
- Solve problems deciding which operation to use.
- Be able to write statements such as 39 x 7 = (30 x 7) + (9 x 7)

**Times tables**

**By the end of Year 4 children should be able to recall all times table facts to 12 x 12 and use the associated division fact.**

**Fractions.**

- Recognise and show common equivalent fractions.
- Count up and down in hundredths.
- Know that hundredths derive from dividing 1 by 100 and tenths by 10.
- Calculate fractions of a quantity - knowing that I divide my whole by the denominator and multiply that by the numerator.
- Add and subtract fractions with the same denominator.
- Recognise and write decimal equivalents for tenths and hundredths also 1/4, 1/2 and 3/4.
- Know the effect of dividing one and two digit numbers by 10 and 100 and know the value of the digits.
- Round decimal numbers to the nearest whole number.
- Order decimal numbers with the same number of decimal places.
- Solve problems involving measure and money up to two decimal places.
- Children use factors and multiples to find equivalent fractions.

**Measure.**

- Children can convert time from 12 to 24 hour clock.
- Solve time problems converting from hours to minutes, minutes to seconds, years to months, months to days etc.
- Find the area of a shape counting the squares.
- Find the perimeter of a shape and start to give algebraic formulas e.g. to find the area of a rectangle 2a + 2b
- Convert between different units of measure e.g. Km to m, hours to seconds etc.
- Estimate, compare and calculate different units of measure including £ and p.

**Geometry**

- Classify and name different quadrilaterals by their properties -
*square, rectangle, parallelogram, trapezium, kite, rhombus.* - Classify and name different triangles by their properties-
*isosceles, equilateral, right angled and scalene.* - Identify and recognise acute and obtuse angles and order angles.
- Recognise lines of symmetry in 2D shapes and complete symmetric shapes in different orientations.
- Draw and position 2D shapes using coordinates in the first quadrant.
- Complete polygons in the first quadrant finding missing coordinates.
- Translate shapes around the first quadrant - up, down left and right.
- Draw a pair of axis with equal scales.

**Statistics**

- Interpret and represent continuous and discrete data using a range of different graphs including time and bar.
- Use increasingly more complex scales to read data accurately.
- Be able to tell a story from a graph.
