I've received feedback regarding problems with the roundedness riddle; Thank you for pointing it out, there is a typo. My apologies, this is the correct riddle:
The digits of B have a sum of 27.
Rounded to the nearest ten, B is 9 960.
Rounded to the nearest hundred, B becomes 10 000.
What is B? ==
Dear class,
As mentioned in class today, here are the misconceptions from Practice 3.
1) If the question asks for what the digit "stands for" or what is the "value" of the digit, it is asking for the same thing. Give the answer in numerals.
2) When giving answer for place value, it must be accompanied with a 's'. For e.g. tens place; millions place; hundred thousands place.
I did go through them prior to assigning the homework as these are the common mistakes made by pupils. This is why it is important to pay attention in class. Please do your corrections carefully.
Yours truly,
Miss Chan
