Teachers & Tutors: Site material uniquely explains common troubles in terms of steps too large or missing. Plus, this December 2011, 5-phase framework offers a context for mathematics & logic education. Phases 1 to 3 may focus on skills with actual or potential local value for adult & daily life. College-oriented phases 5 & 4 focus on calculus & preparation for it. Phases 1 to 4 may also serve trades & professions not dependent on calculus.

Two Road Safety Messages/Questions

1. On what side of the street should you walk on when there are no side walks?

Answer: If you have to walk along a street without sidewalks, try to walk on the side which allows you to face oncoming traffic. Then you can sidestep oncoming traffic if need be, or see what hits you. Otherwise, you are trusting that all drivers behind you, sleepy or not, will see you.

This suggestion or guideline may not apply to all circumstances. The advice here does not apply to travel in one direction along one-way streets. The advice here does not apply if you are at the head or in the middle of a column of people walking with their backs towards oncoming traffic. But the people at the rear of the column with their backs towards oncoming traffic may have cause for complaint. This advice also does not apply when following it means crossing a dangerous flow of traffic.

The other day, driving into the sun, I drove through a pedestrian crossing. I did not see a mother and child about to cross. That was near miss - an accident that could of been.

You too may have the legal right to walk on either side of a road, or to cross. But put safety first. Right of way does not guarantee drivers will miss you, even though most if not all, do not want to hit you.

even when you have have the right of way in principle, but it does not hurt to look both ways when crossing a street, even a one way street, and its does not hurt to walk not on the road, or at least on the road and facing the traffice to seee what is coming, sensibly or not. Good luck.

2. What is the Best Way to Keep your hands or limb?

Do drive with you hand or arm through a car window. That invites problems if the car comes to close to another vehicle or stationary object.

Avoid driving bicycles and motorcycles or bikes on lanes and roads shared with cars, trucks and buses. In the case of an accident, riders in the latter have some protection because they are surrounded by metal - the car shell. But on a bicycle or motorcycle or motorbike in case of an accident, there is no metal shell between you and the ground, or you and another vehicle in case of an accident.

Parent-friendly Work Booklets for ages 3+ to 13 Use these or others to check or build skills.

Mathematics Skills For Ages 3 to 14

Skills with take home value

Basic skills include time-date-calendar Matters; money matters; map, plan and scale diagram matters;counting, measuring and figuring; decision making with logic and likelyhood; being careful and being aware of the domino effect of mistakes; reading and writing with precision.

Is your child able to add, subtract and multiply amounts of money, work with fractions, work with clocks and calendars, work with maps and plans, and measure length, weight-mass and volume? Schools may promote your son or daughter without providing basic skills in reading, writing and arithmetic.

Arithmetic and Number Theory Skills

Algebra Starter Lessons

1 Working With Sets
2 Formula Forward Use - Evaluation
3 Solving Linear Equations - Skip first step with students able to solve 1 eqn in 1 unknown.
4 Computation Rules and Function Notation
5 Real Numbers
6 More Less Greater Than Inequalities and Comparison
7 Axioms Logic and Equivalent Equations
8 Unifying Theme For Algebra
9 Proportionality Backwards and Forwards
10 Examples of Algebraic Reasoning
A Origins of Counting and Figuring Methods
B Real Numbers Extrinsic Development


Site coverage of formuala evaluation format, of computation rules and axioms, and of the forward and backward use of formulas and proportionality relations lessens the amount of natural talent needed to understand and explain algebra.

Geometry - maps plans trigonometry vectors

1 Maps Plans Measurement
2 Euclidean Geometry - Constructions + extras
3 Cartesian and Polar Coordinates
4 Lines and Slopes Take 1
5 What is Similarity
6 Trigonometry first steps
7 Complex Numbers
8 Unit-Circle Trigonometry
9 Lines and Slopes Take 2 with tangent function
10 Intersecting Straight Lines and Transversals
11 Parallel Straight Lines and Transversals
12 Function Translating and Rescaling
13 Vectors
14 Degrees to Radians and Radians to Degrees
15 Arc or Inverse Trigonometric Function

Pre-Teen and young teen mastery of skills and practices which should be common with map-plans-diagrams drawn to scale, contour interpretation included, has actual or potential take-home value for daily- and adult-life in solving routine problems. Elevating some practices to principles, axioms or postualates, provides a base for analytic and Euclidean geometry, an analytic view of similarity, and an efficient mastery of trigonometry and complex numbers. Right triangle trigonometry provide an analytic alternative to solving geometric problems by drawing diagrams to scale.

More Algebra

Natural-Logarithms Exponentials Powers Roots
Five Polynomial Operations
Quadratics Geometrically
Functions
5 Factored Polynomial Sign Analysis Examples
Rewriting algebraic substitution as function substitutions

The first topic leads to a full high school level theory for the forward and backward mastery of growth and decay models and for definition, range and domains of radicals, roots and powers. The next two topics make quadratics and polynomials easier to learn and teach. Site coverage of functions turns vertical and horizontal line rules into computation methods for evaluating functions.
