Frequently asked questions
▸How should probabilities be written on these sheets?
As a fraction in its simplest form. Where an outcome cannot happen the answer is 0, and where it must happen the answer is 1, rather than 0/8 or 8/8. The instruction line on each sheet says so.
▸Why does the question not tell you how many counters there are altogether?
Because finding the whole is part of the question. The parts are given and the child adds them to get the total, then writes the part over that total. If the total were printed, the question would just be simplifying a fraction.
▸Is probability a Grade 5 topic?
In the Australian and Ontario curricula, yes — Ontario names fractions for probability at Grade 5 specifically. US Common Core has no probability standard at this grade and introduces the topic at Grade 7, so under Common Core this is early work rather than required work.
▸What does the second sub-skill ask?
How many counters or spinner sections have to change colour before two outcomes are equally likely. It is not simply the difference between the two amounts: changing one counter from blue to red moves both totals at once, so the answer is half the gap.
▸Can I control how many questions are on the page?
Yes. Use the question-count stepper before printing, and press Shuffle for a fresh set at the same level.
