Why am I learning this?

Mathematicians are not the people who find Maths easy; they are the people who enjoy how mystifying, puzzling and hard it is. Are you a mathematician?

Comment recorded on the 21 October 'Starter of the Day' page by 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."

Comment recorded on the 28 May 'Starter of the Day' page by L Smith, Colwyn Bay:

"An absolutely brilliant resource. Only recently been discovered but is used daily with all my classes. It is particularly useful when things can be saved for further use. Thank you!"

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.

"Don't know what key should be used for the multiplication sign with a German keyboard?"

Transum,

Monday, December 21, 2015

"Hello Quasimodo4711 in Germany. None of the answers to this exercise require a multiplication sign. When two or more terms are multiplied together they can be shown without a sign. For example 6 times b is 6b and 5 times x times y times y is 5xy2."

Collecting Like Terms - This is where you would start. It is important to know which terms are 'like' and can be combined into one term.

Level 1 - Simplify simple expressions by writing them in a more compact form

Level 2 - Simplify some slightly more difficult expressions

Factorising - The next step is to understand how expressions can be simplified by factorising them.
