Further Algebra

Posted on February 5, 2013 by admin

This another sec­tion where all the ques­tions are in the B to A* range. I think that algebra’s rep­u­ta­tion as being very dif­fi­cult is exag­ger­ated. Like all maths top­ics if you really get to grips with the basics, you’ll be … Con­tinue read­ing →

Linear Graphs

Posted on January 31, 2013 by admin

Percentages

Posted on January 24, 2013 by admin

This sec­tion builds on Unit 1 Sta­tis­tics and Num­ber, Sec­tion 2 Frac­tions, Dec­i­mals and Per­cent­ages. It’s my kind of maths, mainly because it’s not really math­e­mat­ics it’s just arith­metic. I think if you learn one or two def­i­n­i­tions and do … Con­tinue read­ing →

Sequences and Proof

Posted on December 6, 2012 by admin

When I started look­ing at “Sequences and Proof”, I fell into the trap of look­ing at some of the most dif­fi­cult ques­tions (A and A*) first. What a sur­prise to find that I couldn’t do them! I now think it’s … Con­tinue read­ing →

Multiplication Grid, The Grid Method of Multiplication and Multiplying Decimals using the Grid Method

Posted on October 8, 2012 by admin

I decided to inves­ti­gate the grid method of mul­ti­pli­ca­tion because my son, in his first year of sec­ondary school (Year 7), came home with his first bit of maths home­work. The home­work included the fol­low­ing mul­ti­pli­ca­tion:- 7.23 x 6.3 My son … Con­tinue read­ing →

How to Divide Fractions, Including Mixed Numbers and Improper Fractions

Posted on September 26, 2012 by admin

Most peo­ple imag­ine that divid­ing by a frac­tion will be very com­pli­cated but it’s really quite straight­for­ward. You just have to “flip” (a tech­ni­cal maths term) the divid­ing frac­tion by swap­ping the top num­ber (the numer­a­tor) with the bot­tom num­ber … Con­tinue read­ing →
