Have your gifted students read  logic chapters 1 to 5  in online volume Three Skills for Algebra  for greater skills & confidence in  work 
and study.

tell students to read notes and textbooks like a lawyer, so that no nuance, no subtlety and no clause escapes their attention.

 Logic chapters 1 to 5  re- appear not in sequence, as is or longer,  in  Volume 1A,  Pattern Based Reason, Bon Appetite.

Logic Mastery
 Amazing, Amusing, Amorous,  Delicious, Delightful, Edifying, Strengthening Elixir. 
It eases work & learning difficulties Makes the hard easier. Opens eyes. Leads to greater precision.
in reading and
writing

Tell students that Logic mastery makes the hard, easier. Logic mastery  leads to better, stronger and richer comprehension.  Logic mastery  improves reading and writing.  Logic mastery ease learning difficulties.  Logic mastery gives a headstart.  In sum, logic mastery  will develops critical thinking, improve reading and writing, and give a firmer base for work and studies at many levels. Good luck.


After logic  (a) continue reading Three Skills for Algebra, chapters 8 to 14  and do so alongside site area on solving liinear Equations ; or (b) see this calculus starter lesson and Volume 3, Why Slopes  & More Math, chapters 2 to 6. In Volume 2, Three Skills for Algebra,  a 4th skill for algebra appears in Chapter 14. It provides a unifying theme for high school mathematics - equations and formulas may be used forwards and backwards, directly and indirectly, numerically in arithmetic solutions & with literals in algebraic solutions.

What may be learnt and when depends on how skills and concepts are developed. Making the hard easier and clearer will allow earlier & richer development of skills and concepts.


Try the Twiddla Whiteboard. In principle, it  allows to people to draw and chat together online on a copy of this webpage or a clean sheet. The chat may be via text or audio.  Visit www.twiddla.com to set up whiteboards to work with the webpage of your choice.

For online automated help in senior high school maths & calculus, visit  quickmath.com  For Automatic Calculus and Algebra Help with derivatives, integrals, graphs, linear equations, matrix algebra, visit calc101.com  With  overlap, each site quickmath & calc101offers a different range of services, some free, some not, all based on webmathematica. Good luck.


Chapter 10
The Transition

Intermediate level courses in say secondary school should build a mastery of logic, of basic trigonometry, and of the symbolic and algebraic way of writing and thinking. The exposition of trigonometry is simplified by a previous or concurrent description of complex numbers. Here set theoretic concepts are welcome but the mastery of the symbolic-algebraic writing and thought is more important. It is needed even for the exposition of set theoretic concepts. Intermediate level instruction builds on the previous mastery of counting, arithmetic and simple formulas (proven or not). The first objective need not be the deductive or Euclidean representation and derivation of mathematics but simply a familiarity with logic and the algebraic way of writing and thinking. The latter may stem from many illustrative strands of deduction and algebraic thought.

The aim here is to extend the common knowledge of mathematics. Ease of exposition will be the guide. Topics not mentioned below could also be added to the core proposed below. The companion works Three Skills for Algebra and Why Slopes and More Math includes much, if not all of the following material. The following words may be regarded as their defense.

Will provide an alternative to Chapter 11 later, most likely in the Parent's Area: Help Your Child or Teen Learn 

Most students in high school are not heading for calculus, but most topics in high school mathematics are present due to calculus.  Preparation for calculus demands their coverage at  full strength.

See too, this site 55+,  Math Education Essays. Site areas and pages provide pieces of the a Mathematics Education, Jigsaw Puzzle, in formation.

-Inductive principles for course design & delivery  require a clear description of where and how skills and concepts may rest on earlier ones, so that difficulties may be explained and remedied by looking for  what was missed or forgotten in earlier studies. 


Mathematics is a demanding subject. All errors in notation and comprehension need to be identified and corrected. In reading, spelling and writing, students have to learn all the letters in the alphabet, not just some. and memorize spelling. Anything less implies difficulty.

Likewise in mathematics, students have to master key skills and concepts, one at a time and one after another. Anything less implies difficulty.


Modern mathematics curricula introduced an inconsistency into course design and delivery. They did not sanction the use of decimals nor the use of diagrams in skill and concept development but decimal arithmetic and diagrams are needed for student comprehension and for an operational mastery of quantitative skills. That implies the need for an mixed-math curricula based on a systematic development of operational skills, sufficient for applications and sufficient to provide a base & context  for  the very optional study of pure mathematis.
