Feedback on Marked AB 1.1 and HW 8/1

Math Homework 8/1 CB Pg 8

Dear Parents,

The following are common errors that I observed while marking the girls' 1st assigned work, AB 1.1:

1) Spelling  error for numbers like '90', '14', '15' and '40'. They tend to spell it as "Ninty" instead of "Ninety","forteen" instead of "Fourteen", "Fiveteen" instead of "Fifteen" and "Fourty" instead of "Forty"

2) Write the given number, 587 123 in words, here are some common mistakes,
Five hundred and eighty(-)seven thousand, one hundred and twenty(-)three.

Five hundred (and) eighty-seven thousand, one hundred and twenty-three.

FIve hundred and eighty-seven thousand(,) one hundred and twenty-three.

Five hundred and eighty-seven (thousand), one hundred and twenty-three.

Answer: Five hundred and eighty-seven thousand, one hundred and twenty-three.
The words/symbols highlighted in brackets are commonly missing.

I have highlighted the above to the girls in class today and will be returning the books to them  to bring home tomorrow.

Please note that I will not be writing the correct answers for them in their exercise. This is deliberate on my part as I would like to train them to correct their work independently.  I would like the children to spot the errors themselves to find out "where" they had gone wrong. I hope you agree wth me in this "training" and practise with your child as well. Try not to "spot" errors for your child. Allow them to learn how to spot their own mistakes.

Cheers,
Mrs J Chua
