I only have 1 HYPY resource and it is this 'book' which I bought more than a year ago! After using it twice, I have to say that I like it and find it useful. It has a hardcover which allows it to stand up like an A-stand and works like a mini flip chart.
Here's why I find this a good buy:
:: Well organised
The very first page of this book has a pull out flap which basically is a summary of all the 声母 and 韵母combinations. This works for me as I like that from a parental standpoint, without having to go to the flap, I can see the various combinations / blends!
:: Hot Tips
Thereafter, there are pages of how the various combinations should written - when do we use the accent dots (such as nǚ) and when it is not needed. I don't know what about you but Hot Tips like these are definitely useful for me as I have basically "returned" these back to the teachers years ago!
:: Easy blending with "Flip the Cards" design
With the 声母 and 韵母 printed on separate pieces, it allows the child to have a visual aid as to how the sounds can be 'blended' or formed. In addition, all the 声母 and 韵母 are color coded for easy reference too.
:: Clear examples
Above every 声母 and 韵母 card, there are examples of how the words presented in a pictorial format too) are being used. I wish that they have more of these but I also understand that the book, being only an A5 (in size), would not be able to incorporate many of such examples. So what Dumpling and I do is to talk about it and have a quiz as to how many such words we can come up with.
:: Pronunciation Tips
Towards the end of the cards, there are even tips on how to produce some of the sounds! How's that for a lesson for the parents too? :p
:: Rhymes practice
The last pages of the 'left' cards also feature some simple rhymes which are meant for the children to have a go at practising the HYPY. These would be great for children who have not yet developed a sensitivity towards the pronunciation of words like 说 (是 S 还是 Sh 呢?) , 车, etc.
What other HYPY resources do you use at home? I would love to know your recommendations too!
