Talk to your child drawing attention to mathematical ideas in the world around us and ask questions that need answers in mathematical language.
Play with your child. There are many games that have fairly obvious mathematical content and many others provide opportunities for mathematical conversation.
Make use of everyday situations. Your child needs to see mathematics at work in real life.
Look for situations that are particularly mathematical and and work together on them.
Make an effort to remember that mathematics is not just arithmetic. Mathematics includes logic and geometry as well as measurement and number. This means that it includes planning, sorting and classifying, following instructions - particularly with diagrams, patterns and shapes in two and three dimensions, volume and capacity as well as length, reading scales and dials.
