So one day recently I was bored, and then the following rushed onto the page:
Half of a big pizza is equal to two small pizzas – rewrite this in as precise way as possible.
Is this 3 hours or 1/4 of a pizza?
How many hours equals 1/4 of a pizza?
Apologies to those for whom a clock face is a historical artifact.
How do I know it’s a pizza and not a cake?
Does half a day include half the night?
There are four feet in our yard, mine and my sister’s.
Would you prefer 1/2 of a round pizza or 1/2 of a square pizza?
Are ratios numbers or fractions (or neither) ?
Fractions are parts of the same whole. OK, I’ll have 5 quarters of that pizza (5/4 is a fraction, isn’t it?)
You cut, I choose !
This year fractions are parts of a whole. Next year fractions will be numbers. I guess the other party won the election.
2/3 and 4/6 are equivalent fractions. Equivalent to what ?
The word “fraction” has the same root as “fracture”. So something got broken. I think it was my faith in common sense.
The Common Core test question asked – How long is 3.25 hours. This could be 3 hours and 25 minutes or 3 hours and 15 minutes. I guess it depends on the grade level.
Back to the heavy stuff next time !
