Description
By Alan Selby, author of books and further webpages on learning and teaching mathematics and pattern based reason. Site material may develop critical thinking, improve reading and writing, and give a firmer base for secondary and college studies. For instruction, site pages point to (i) a greater & clearer use of words and geometry in the introduction and development of algebra; (ii) geometric and algebraic calculus previews; and (iii) a leaner, secondary mathematics curriculum before or with calculus.
