Hours To Go

A Maths Starter Of The Day

Metric Time

The day is divided into 100 parts (centidays) and the time is given to three decimal places. Think of it as a percent of the day that has passed.

Mid-day will be 50.000 LMT (Local Metric Time) in metric Time.

The current time is:

?

How many full hours are left until the end of the year?

Mayan Time

 
 
 
 

 
 
 
 

 
 
 
 

 
 
 
 

The Mayans used a vigesimal (or base-20) numeral system. Mayan numerals use only combinations of dots (ones) and bars (fives) to form numerals for 1 to 19, and a stylised shell glyph for zero (not shown here).

Hexadecimal Time

The day is divided up into 65536 parts and written in hexadecimal (base-16) notation (A=10, B=11 ... F=15). The "0x" at the begining is just to signify that it is in hexadecimal notation, we could just leave it off or use some other signifier.

Binary Time

               
               

Like hexadecimal time, the day is divided into 65536 parts, only we display it as a binary number using squares for bits, here using dark squares to represent 1 and white for 0.

Octal Time

Octal Time uses a base-8 system (digits 0-7). The day is divided into 32768 parts for a total of 5 octal digits. The right-most digit updates about every 2.6 seconds (half the speed of hexidecimal time).

Base 64 Time

Base-64 uses ASCII characters (in ascending order: A-Z, a-z, 0-1, +, and /).

Can you figure out how you would convert Base 64 time to mormal time?

Topics: Starter | Time

  • Mr Ditta and 9Y-Ma1, Stokesley School
  •  
  • 9Y-Ma1 argue that you have failed to subtract 1 hour on the last sunday of October hence 1 hour needs to be added accordingly.
  • Year 6, St. Philip's Uckfield
  •  
  • We think that you have forgotten the extra hour when the clocks go back.
  • Mary Brentnall, marybrentnall@hotmail.com
  •  
  • What about the extra hour when the clocks go back?
  • Transum,
  •  
  • The extra hour has now been included in the answer. Thanks Mr Ditta and 9Y-Ma1 at Stokesley School, Year 6 at St. Philip's Uckfield and Mary Brentnall.
  • Mr Trainor And His P7 Class(All Girls), Mercy Primary School, Belfast
  •  
  • My Primary 7 class in Mercy Primary school, Belfast, look forward to your mental maths starters every morning. The variety of material is interesting and exciting and always engages the teacher and pupils. Keep them coming please.
  • Josh, BCJS Year 6 6J
  •  
  • At BCJS in Mr Jenkins maths group, on 21/10/13 at 12 o'clock. The majority of the class said the answer was 1717 hours until the end of the year. The method we did was 71 days x 24 hours = 1704 add 12 hours = 1716 add 1 hour because of the time change = 1717. So our last answer was 1717.

How Not To Be Wrong

How Not To Be Wrong

The maths we learn in school can seem like an abstract set of rules, laid down by the ancients and not to be questioned. In fact, Jordan Ellenberg shows us, maths touches on everything we do, and a little mathematical knowledge reveals the hidden structures that lie beneath the world's messy and chaotic surface. In How Not to be Wrong, Ellenberg explores the mathematician's method of analyzing life, from the everyday to the cosmic, showing us which numbers to defend, which ones to ignore, and when to change the equation entirely. Along the way, he explains calculus in a single page, describes Gödel's theorem using only one-syllable words, and reveals how early you actually need to get to the airport.

What more could the inquisitive adult want for Christmas? This book makes a cosy, interesting read in front of the fire on those cold winter evenings. more... #ad

Graphic Display Calculator

This handheld device and companion software are designed to generate opportunities for classroom exploration and to promote greater understanding of core concepts in the mathematics and science classroom. TI-Nspire technology has been developed through sound classroom research which shows that "linked multiple representation are crucial in development of conceptual understanding and it is feasible only through use of a technology such as TI-Nspire, which provides simultaneous, dynamically linked representations of graphs, equations, data, and verbal explanations, such that a change in one representation is immediately reflected in the others.

For the young people in your life this is a great investment. Bought as a Christmas present but useful for many years to come as the young person turns into an A-level candidate then works their way through university. more... #ad

Math with Bad Drawings

I had been tutoring the wonderful Betsy for five years. When the day came for our last ever session together before the end of her Year 13, I received this beautiful book as a gift of appreciation.

This a very readable book by Ben Orlin. I'm really enjoying the humour in the writing and the drawings are great.

Ben Orlin answers maths' three big questions: Why do I need to learn this? When am I ever going to use it? Why is it so hard? The answers come in various forms-cartoons, drawings, jokes, and the stories and insights of an empathetic teacher who believes that mathematics should belong to everyone. more... #ad
