If you want to teach or support your child in learning their letters and then to read - buy this book 1 and 2,3,4,5,6 and 7!
Please do not (as I did) buy the other set of books ALSO FROM JOLLY PHONIC (Jolly Phonics Workbooks: Books 1-7 ) because they are small, black and white and very, very dull.
This set of books is colourful, apealing, full of stickers with stick games, packed with different activities. My daughter aged nearly three then three years old loved and loves these books.
How to use them? Best to get going with letter on as many levels as possible. We used a DVD called FUN WITH PHONICS (which is the BBC in conjunction with Jolly ish phonics). It has great animation for each letter which your kids will soon learn off buy heart. After a couple of months of that, my girl knew most of the letters (exept for some confussion with - p,b,d, which is always a bit difficult for kids in the begining). Once she knew her letters, these books came alive to her and she'll sit down with me for an hour with one.
There are also some wipe clean material out there to write/trace letters and words. Lots of wipe clean books (wright with a felt-tip then wipe off) are available, but the most popular at home has been small wipe clean cards. Why? Kids are smaller than us, at the table its hard to reach so far over to the top of a book whereas the cards all have words along the bottom, exactly where little hands can reach them.
