Singapore Expats

Hi,
I am new to the forum,very much interested in Singapore education system.but you could say I am fan of Singapore system.Really!
I am homeschooling my kids,so have some query about books selection.
For oral and listening I selected few books,but among these which oral and which listening book is too much good.
oral:
1)A Guide To English Oral Skills (For Elementary Level)
Publisher : Raffles Publications
2)Oral English Picture Discussion For Lower Primary Levels
Publisher : Singapore Asian Publications

listening:
1)P1 Just Oral Practice & Listening Comprehension (2 In 1 Series)
Publisher : Just Education Publishers Pte Ltd
2)P1 Oxford Primary Essentials English Oral And Listening
Publisher : Marshall Cavendish International (Asia) Pte Ltd

Experiences and guidance would be highly appreciated.
If any body knows any English and Maths tutor for Primary level,who could give classes online.Kindly contact me.
Thanx.......................
