Number fact challenge

We have introduced a Mathematics Challenge. This will run for the rest of the half term.

In Reception, Year 1 and Year 2 we are challenging every child to recall addition and subtraction facts.

In Key Stage 2 we are challenging every child to know their times tables and associated multiplication and division facts.

Please support your child as they work through the challenges.

Enriching maths at home

We highly recommend look at National Numeracy's Family Maths Toolkit. The charity National Numeracy is dedicated to enhancing a numerate society and they have collected together some excellent ideas for incorporating maths into everyday life.

Calculation videos

To help explain how we teach calculation in maths, the Maths Team has put together a series of videos to show how we use resources to teach some of the trickier calculation methods. Please check back here regularly  as the site will be continually updated.

 

 

 

 

 

 

 

 

 

 

 

This video explains a method for identifying prime numbers by using multiples to eliminate composite numbers. It is a method dating back to ancient Greece known as the sieve of Eratosthenes (named after a chief librarian at the great library in Alexandria, Egypt). If you would like to have a go yourself, Nrich (run by Cambridge University) has provided some helpful  instructions.  https://nrich.maths.org/7520&source=blog 

There is also an interactive version available that takes you through finding prime numbers step-by-step. http://www.transum.org/software/Sieve_of_Eratosthenes/

 

 

 

Maths enrichment

We encourage our children to appreciate the wonder and beauty of maths as well as its importance as a life skill. That is why we have included some fascinating alternative ideas and famous maths problems to help children expand their minds when they think about what it means to "do maths."

At school, we use the standard algorithm for written multiplication shown in the video above. However, throughout history and across different cultures there have been many different methods developed to multiply numbers efficiently. Nrich has provided videos to show different methods of multiplication. Can you figure out how these methods work? Can you re-create what is happening?  Why not try a few calculations of your own?

Multiplying with lines

 

 

Gelosia multiplication

 

 

Gelosia multiplication was made simpler in the 16th century by Scottish mathematician and philosopher John Napier. He developed rods known as "Napier's bones" with the basic multiplication facts already written on the rods to help speed up multiplication done by the gelosia method.

 

 

What if it is impossible to reach the end?

This video explains Xeno's (Zeno's) paradox about Achilles and the tortoise. This is a famous thought experiment from ancient Greece. Can you explain how Xeno's paradox works? What is the link you see here to fractions?
