# Maths in Year 3

The Year 3 team would like to provide you with an overview of the maths topics this year, as well as different ways you can help. We hope you find this document helpful. This includes the skills that have been introduced by the new National Curriculum.

### An overview of the Maths concepts and skills in Year 3

**Number**

- Compare and order numbers up to 1000
- Read and write numbers to at least 1000 in numerals and in words
- Recognise sequences of numbers
- Use simple fractions e.g. 1/2, 1/4 , 2/3, 5/8
- Recognise simple equivalent fractions e.g. 2/4 and 4/8
- Be able to use decimal notation for money e.g. £2.45
- Be able to use their multiplication knowledge to help with division
- Use mental recall of the 2, 3, 4, 5 and 10 multiplication tables
- Begin to know 6,7,8,9, multiplication tables
- Use mental strategies for addition and subtraction
- Solve multiplication and division problems that may give remainders
- Add and subtract 3-digit numbers using written methods
- Recognise, find, write and add fractions of a discrete set of objects: unit fractions andnon-unit fractions with small denominators
- Recognise and show, using diagrams, equivalent fractions with small denominators.

- Measure, compare, add and subtract: lengths (m/cm/mm); mass (kg/g);volume/capacity (l/ml)
- Read simple scales that are numbered or partially numbered
- Use standard units of time
- Read a 12-hour clock and calculate time intervals
- Use vocabulary such as a.m./p.m., morning, afternoon, noon and midnight
- Know the number of seconds in a minute and the number of days in each month,year and leap year
- Recognise angles and estimate their size
- Estimate the answer to a calculation and use inverse operations to check answers

Count up and down in tenths; recognise that tenths arise from dividing an object into10 equal parts and in dividing one-digit numbers or quantities by 10

**Shape and Space**

- Recognise a range of 2D and 3D shapes
- Sort 2D and 3D shapes according to their properties
- Recognise nets of familiar 3D shapes
- Identify horizontal, vertical, perpendicular and parallel lines in relation to other lines.
- Use directional vocab to describe position and movement e.g. clockwise, quarter turn

- Measure the perimeter of simple 2-D shapes
- Tell and write the time from an analogue clock, including using Roman numerals from I to XII, and 12-hour and 24-hour clocks

**Data Handling**

- Understand and be able to use a variety of ways to collect data
- Construct bar graphs and pictograms to represent data
- Interpret information from tables, lists, bar charts and pictograms
- Read scales labeled in 2’s, 5’s and 10’s

**Problem Solving**

- Decide on a strategy to use when presented with a problem
- Make connections and apply their knowledge in a range of contexts
- Try different approaches and find ways of overcoming problems
- Use and interpret mathematical symbols and diagrams
- Put problems into their own words
- Discuss their work and explain their reasoning
- Be able to review and check their work with alternative method.

### Helping your child with maths

Below are few examples of different ways to help your child enjoy maths while also helping them develop new skills:

- When cooking, encourage your child to measure weights and capacity
- Point out the different shapes to be found around your home
- Take your child shopping and talk about the quantities of things you buy
- Help your child become familiar with money and work out how much things cost
- Look together for numbers on street signs and car registration; help them recognisethe importance of number in our every day lives
- Use the Internet to play maths games
- Obtain a times tables CD to sing at home or in the car
- Encourage your child to tell you what the time is or what time they need to leave inorder to arrive on time; it can be useful if they have their own watch
- Interpret football results tables
- Ask your child to take a fraction (2/12) of the pizza
- Ask your child to share out their packet of sweets for their 5 friends. Can they tell you how many sweets each child will get before they share them out? Can they say how many sweets each child would get if there were only 3 children?
