i- Science Workbook Teacher's Edition is identical to the workbook. Answers to workbook are printed in the teacher's edition.
Above is an extract from the preface of the i-Science Series (reproduced with the permission of the publishers).
i-Science is ideal for both classroom and home use for 1st - 6th grades.
There is no need for placement test for i- Science.
If you are buying the Teacher's Guide, it may not be necessary to buy the Textbook.
Note: Formal instruction in science in Singapore does not begin until 3rd grade, hence this series is pretty basic at the 1st -3rd grade level.
