# Year 3 Maths

It is our aim that all children in Year 3 meet the following expectations:

**Number**

- 1. Read and write numbers to 1000 in numerals and words.
- 2. Know the value of each digit to 1000 e.g. 874 is the same as
- 800 +70+4. (874 =800+70+4)
- 3. Count in intervals of 2, 3, 4, 5, 8, 10, 50and 100.
- 4. Find 10 and 100 more and less than any given number to 1000.
- 5. Order Numbers to 1000.
- 6. Add and subtract numbers up to three digits using a formal column method - see calculations policy for more information.
- 7. Use inverse operation to check their answer.
- 8. Use times table knowledge to support multiplication and division problems.
- 9. Know and recognise what the symbols +,-,x and ÷ mean.
- 10. Know when to use which of the four operations to solve problems.

**Times tables**

**By the end of year 3 it is expected that children know the following times tables:**

**1, 2, 3, 4, 5, 8, 10. They can recall facts to 12 x in each table and use these facts to find division equivalents.**

**Fractions**

- Count up and down in tenths
**.** - Children connect tenths to place value and division of 10.
- Recognise that tenths are found by dividing a number/ quantity or object into 10.
- Recognise, find and write fractions of a quantity (using objects).
- Recognise and show equivalent fractions of a quantity - using objects e.g. 1/2 is the same at 2/4 half of eight apples is four and two quarters of eight apples is four.
- Add and subtract fractions within one whole with the same denominator.
- Compare and order fractions with the same denominator - children can place fractions on a number line recognising the value of each fraction within 1.
- Solve problems involving all of the above.

**Measure**

- Children measure, add and subtract accurately using appropriate units - length m,cm and mm; mass kg and g and volume / capacity l and ml. They can compare units e.g. 5m = 500cm and record using mixed units 1kg and 200g.
- Find the perimeter of a 2D shape.
- Add and subtract money using £ and p. Giving answers as £ and p separately.
- Tell the time with increasing accuracy to minutes using, 12 hour, analogue including Roman numerals 1 to X11. Use and read a digital clock to 24 hours
- Know how many seconds in a minute, minutes in an hour, days in each month and year including leap years.
- Find lapsed time between events.

**Geometry**

- Draw 2D shapes and make 3D shapes using modelling equipment and recognise shapes in different orientations.
- Recognise horizontal and vertical lines. Recognise pairs of perpendicular and parallel lines.
- Recognise right angles and understand that 2 right angles equal half a turn 3 equal three quarters if a turn a 4 a whole turn.
- Recognise angles greater and smaller than a right angle and know them as acute and obtuse.
- Recognise symmetrical and none symmetrical shapes.
- Describe shapes using the above language.

**Statistics**

- Interpret and present data in bar charts, pictograms and tables.
- Use scales in steps of 2, 5 and 10.
- Solve one and two step problems presented in bar charts, pictograms and tables
