Hi, page
221 of the EYE handbook will help you research literacy and
page 239 explores how maths relates to children's everyday lives
Activities that can be done at home: consider how your setting works in partnership with parents and the different activities that are shared between the children's homes and the setting.
Importance of making it fun: use your knowledge of how children learn best when they are interested and enjoy what they're doing in a relaxed atmosphere.
Importance of not making the activity too long: use your knowledge to support the children by explaining how concentration and focus can diminishes if the activity goes on for too long and they lose interest in what's happening/going on.
How you use math and literacy in everyday conversation: think about how we talk about the language of maths - numbers, measurements, sizes, shapes, space and distances, time, patterns, matching & sorting, estimating. and literacy how reading, writing, speaking, talking and listening are part of every day.
