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

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;

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.

Preparing for Science Courses

In high school, a student will be good in science and technology courses only if he or she masters logic,  fractions and solving two equations in two unknowns. 

Before your son or daughter takes a science lesson, teach them to cook. Following a recipe, requires collecting all the ingredients, reading and understanding instruction, stirring, mixing and apply heat, and then cleaning up.

Cooking at home is good practice for science " experiments." Every son or daughter, no matter how intelligent, who is barred from cooking is at a disadvantage. Sons, and not only daughters, would benefit from the recipe following skills acquired in cooking. Besides this cooking is a survival skill before and after leaving home.

Labs and Science experiments in school in principle represent processes with repeatable and reproducible results. Yet as with cooking, the first time one follows a recipe, the result may not be as it should be due to errors in the process. Students are often graded on experiments done once. So care is required in collecting all the ingredients, reading and understanding instruction, stirring, mixing and apply heat, recording what happens and then cleaning up.

With grading and marks dependent on what is reported, and its agreement with expectation, honest reporting of what happened may suffer -- reporting that a process failed to give the right result is penalized. But in actual science labs, a new procedure is non-routine. It is usually tried and repeated until it becomes routine. Then results become repeatable and reproducible. (A student may quote this whole paragraph in response to being penalized for not falsifying (cooking) the results of in-class experiments. The teacher in reply should direct the student to learn to cook or follow recipes at home.)

Science labs or experiments in school may also be used to illustrate situations and thereby provide evidence for this or that physical or chemical principle. The notion of a science experiment comes from the ideas of creating a test to decide whether or not a law (relationship) holds or a process works. An understanding of the benefits and limitations of rule and pattern based is required. The latin roots of the word "prove" is test. Putting a concept to the proof means to test it. Mathematics and science depend on proofs or tests of methods and wanted conclusions. 

The presentation of science (chemistry, physics and biology) in high school and college is largely descriptive. But chemistry and physics may further involve computation and chains of reasoning (stories) to follow and understand. Computations in chemistry and physics at the high school level in North America regretfully only relies on a mastery of algebra, a little trigonometry and no calculus.   The ability to solve two equations in two unknowns, to graph one quantity versus another, to use quadratic formula, to use a calculator, to follow short chains of reason is sufficient, regretfully, to shine in the theoretical and computational parts of most North American high school science courses.

Explain the the first  logic chapters with your child. Start with the easiest ideas first. If your child does not understand, wait. These appetizers are  hard for a ten year old, less hard for a fourteen year old, and hopefully very easy for a sixteen year old.

D What to do in School & Why  

E.How to Study Mathematics


To read, write and spell, your children need to learn and memorize the alphabet. Anything less would be absurd. That being said, learning and using mathematics demands that your children meet key skills and concepts, and not skip any. Where local schools do not provide the latter, you need to provide remedies.

Care and Precision: If your child  can learn to follow multi-step methods carefully and precisely in arithmetic, he or she may do so  in other subjects, as well. Get your child or teen, if you can, to sit down and study. Suggest he or she aim for skill and concept development and perfection for their own sake, not that of their teachers.

The will to learn is the key to success in school.  Parents do have to be educated to support or guide their children and teens. What matters more is support for the will to learn, for children and teens to be  told to try to learn and to ask teachers, their schools or classmates for help and more help, as needed. Teachers and parents need to push students, help them find the will to learn, teamwork helps.

The main reason and focus for high school mathematics is or should be preparation for calculus. That requires skill and knowledge perfection with fractions, algebra, geometry, trig and functions. Many high school programs do not provide this. Make sure alone or with help that your children and teens have a good command of fractions.
