# Imperial Units

## Units of capacity

Gallon refers to the imperial gallon which was used in the United Kingdom, Ireland, Canada, Australia, New Zealand, and some Caribbean countries but not the USA.

Quart as the name suggests is a quarter of a gallon.

Pint - the imperial pint is about 20% larger than the American pint.

Fluid ounce is almost exactly the same as the volume of pure water weighing one ounce.

1 gallon = 4 quarts1 quart = 2 pints1 pint = 20 fluid ounces

This is level 3: units of capacity. You will be awarded a trophy if you get at least 14 correct and you do this activity online.

Comment recorded on the 18 September 'Starter of the Day' page by Mrs. Peacock, Downe House School and Kennet School:

"My year 8's absolutely loved the "Separated Twins" starter. I set it as an optional piece of work for my year 11's over a weekend and one girl came up with 3 independant solutions."

Comment recorded on the 1 February 'Starter of the Day' page by M Chant, Chase Lane School Harwich:

"My year five children look forward to their daily challenge and enjoy the problems as much as I do. A great resource - thanks a million."

## Go Maths

Learning and understanding Mathematics, at every level, requires learner engagement. Mathematics is not a spectator sport. Sometimes traditional teaching fails to actively involve students. One way to address the problem is through the use of interactive activities and this web site provides many of those. The Go Maths page is an alphabetical list of free activities designed for students in Secondary/High school.

Just when I thought I knew all of the imperial units I heard Matt Parker (Standup Maths) list them all, even the more obscure ones, in this wonderful monologue. When you hear their names and their relative sizes you cannot help but be grateful for the metric system which is more common today.

This audio excerpt is from an excellent podcast from BBC Radio 4 called More or Less: Behind the Stats in which Tim Harford tries to make sense of the statistics which surround us. It's well worth a listen if you have an interest in mathematics and statistics and provides real world examples of the maths we learn in school.
