Elliott Fletcher commented on Rounding numbers to a given number of significant figures 7 years, 5 months ago

Hi Stanislav,

In parts,a,b and c, in each question i would write "rounded to" instead of "to". For example, "66565 rounded to the nearest 10" instead of "66565 to the nearest 10". I just think it reads slightly better.

Advice (section)

Part a) i) You say "the following digit is 5, so we round up, increasing 5 by one, becoming 6.", but i think you meant to say "the following digit is 5, so we round up, increasing 6 by one, becoming 7."

a) ii) I would say "Look at digit 5 in the hundreds column", instead of "Look at digit 5", in case the student gets confused with the 5 which is the last digit.

iii) Same as for ii) 

v) I don't think the 9 needs to be in brackets.

b)

ii) and iii) I would write "The" at the start of each sentence.

c)

In the opening paragraph, i would write "up to the nth number of places" instead of "up to nth number of places".

iv) I think there should be a space between "7and" and "is5". I would also put "These are our 4 significant figures" at the end of the sentence, after you have finished all of the rounding.

Not sure if i can write the title for this in a simpler way

I was going to try and use a few less questions, but i wanted to make sure all directions of conversions were covered. (e.g fractions - decimals and decimals - fractions).
