Primary Skill Development

The question of what abilities to develop, why and how why is of interest to students, parents and teachers. Each year of primary, secondary and college level instruction covers more and more logic, language and mathematics skills and practices. Later abilities depend on earlier ones. Primary school lessons in reading, writing and arithmetic usually give and leave a good impression because they provide know-how with value clear to parents, teachers and students. The first least controversial aim of primary level instruction is provide mastery of common skills and know-how. The second more controversial aim is to introduce parental or community concepts of citizenship - there views may widely differ.

The What and the Why

At home, before and in primary level lessons one may or should learn about counting, figuring and measuring in several application areas.

  1. Time, date and calendar matters for daily, family and community events
  2. Counting and Handling money for saving, buying and selling
  3. Using maps and plans for seeing where you and for measuring or calculating distances and areas indirectly
  4. Chance or likelihood or odds for deciding what risks to take or avoid in games and daily life
  5. Units of time, distance, mass, weight alone and multiplied by numbers for describing and figuring.
  6. Solving logic puzzles for sharpening or developing thinking skills

through playful to serious exercises and activities. Learning can be fun and serious. Cooking, building, making, buying and selling provides chances to develop and strengthen counting, figuring and measuring abilities. In cooking, building and figuring, the domino effect of errors may be learnt. Avoiding that domino effect becomes an end, value and tool for skill development. Experience counts. The above application areas should be included in primary instruction because of their currrent or possible future value for life at home, at work and in the street. Most of who can, may remember strongly and then more dimly primary school days as time to play and time to learn skills and things needed for adulthood.

In the foregoing, learning to measure and draw with rulers, tape-measures, protractors and compasses directly or with the aid of maps, plans and diagrams drawn to scale provides an introduction to geometry. In that students may be shown how to draw triangles, rectangles and regular polygons and plans using given data, and then be asked to find missing angles, lengths and areas. Maps and plans drawn to scale may be used to not only to find missing measures, but also to plan and plot routes and detemine location. All that may give a playful to practical geometric command of measurement and estimation with maps and plans drawn to scale before any mention of trigonometry.

Quantitative skills may be further extended through activites and instruments to measure and estimate mass, wieght and volume in a repeatable and reproducible manner. In that basic principles may be introduce and illustated with devices - balances included - whose mechanism are visible and not hidden before the introduction of electronic scales or mechanical boxes whose inner operations is hidden. Calculation methods for volumes, areas and lengths - perimeters included - may be introduced as alternatives to counting or measuring them. Methods to determine measures directly or not should be seen as consistent alternatives, subject to measurement or figuring errors/approximations

The How

Children in the presence of adult or family members who value their skill development will have teachers at home before school and teachers at home and in school who deliberately help or encourage children master common language, logic and mathematics skills and practices. Those children will have a head-start. On the other hand, apart from questions of ability, children who do not have adult or family members near-be to help and encourage learning will have a greater dependence on their primary school teachers for skill development. Those children may need greater attention.

For the application areas above, the mastery of methods - that is, learning to do for the sake of skill and practice mastery has more current or future value for life at home, at work and in the street than fully understanding why methods work. In that, some students require less explanation or less comprehension of why methods work because for them learning to do quickly is their objective. In contrast, some students immediately or eventually need and ask for greater explanation. In the case of counting and figuring with decimals, place value comprehension is a must - cannot be avoided. But in figuring, the addition, subtraction, multiplication and division of decimals may be learnt in all or part by rote in accordance with the abilities and wants of learners and teachers. In that, some students will find it easier to learn to do without explanation while other students find it it easier to do with some explanation.

In my earlier thoughts about developing arithmetic skills, I was advocate of making and even giving a full-explanation of how and why arithmetic methods work due to my then aversion to rote learning. However, the full explanation would likely overwhelm students, most parents and teachers too. So I now I believe full explanations should be available but not imposed. In daily life, we eat, sleep and work with the help of skills or abilities in a practice first, theory unavailable or optional manner. That being said, in mathematics unlike many other disciplines includes a nearly complete explanations for immediate or later comprehension in accordance with the individual wants and abilities. Mathematics skill development may be put practice first and offer more and more explanation as required by the wants of learners or their hoped for work and academic destinations.

Primary school skills in counting, figuring and measuring may be introduced through activities and exercises. First in decimal arithmetic, and then in the evaluation of arithmetic expressions and simple formulas, students should be shown how to do and record work or reasoning in steps that can be seen as done or later for the sake of confirmation or correction. With steps written and recorded, the domino effects of care and of error will be observable.

In the initial introduction and development of mathematics, learning to use methods is far important than learning in full why methods work. Children may expect their formal and informal instructors to give them reliable methods. In that, avoidance of the domino effects of errors may be emphasized as a must for repeatablea and reproducible results not only in arithmetic, but also in all arts and disciplines where skills and practices are multi-step. Avoidance of this domino effect of errors, or being careful to do each step of a skill or practice provides an end, value and tool for skill mastery in general. Figuring well with its avoidance of this domino effect of errors is a sign of wit or intelligence of the practical kind. Adults, teachers and trainers included, need to emphasize for skill development at home, in school and work.

Teachers & Tutors: Site pages offer better or best practices for providing skills - simpler than expected & comprehensive but for exercises. For your charges, your duty is to study them alone or in groups and develop skill building exercises & activities to share. Start now. The effort here is the best I can do. Others are welcome to refine or exceed it. Please do.

The Logic of Injustice: How Texas sent an innocent man to his death - The wrong Carlos. Some judgments are irreversible. Procescution: Where and when prosectors play to win rather than for justice, guilt beyond a reasonable doubt goes unrespected due to prosecutors who putting winning first, those innocence before the law may be convicted. Some procescutors offices in continuing to accuse after a pardon due to reasonable doubt or innocent being shown, may sucessfully oppose compensaton for false convictions by asserting a pardon individual is still under suspicion. Then the pardoned individual or the latter's estate is not compensation for years or decade of improper or false imprisonment, or for execution. Site chapters on Logic
and some in Pattern Based Reason may slowly lead to greater precision in reading, applying and writing laws.

Parent Center: Help your child or teen learn:

Parent-friendly Work Booklets for ages 3+ to 13 Use these or others to check or build skills. Other booklets are available but these booklets allow parents unsure of themselves in mathematics to help their children. The selection acquired in Canada is published in the USA. So it has a US orientation. In retrospect, the selection shows parents what to check with the booklets or by other ways, the choice is theirs. But in retrospect, the selection does not cover integral and fractions liquid weights and measures - ask the publishers to correct that! For ages 9 to 12 say, parents may compensate by showing boys and girls how to use weights or mass, and further measures in food preparation. Beyond that children may be shown how to measure and calculate angles, lengths and areas [proportional amounts too] directly or by using maps and plans drawns to scale. Learning how to gather and measure all the ingredients, pots and pans for a dish or a meal, along with cleaning up sets the stage for like activities or experiments in science courses, and in developing organizational skills, gives boys and girls a head start. Good luck.

Skills with take home value - A few ideas

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.

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.

As invited guest here and elsewhere, if one or more explanations is not to liking, try another. It may be better or just right.

Unsolicited Advice

Learning to do and high marks if it comes to easy is often deceptive - light rather than deep. For that reason, students with learning difficulties determined not to let it get in their way may go deeper and farther than those with none. High marks, if the come easy, may be deceptive - provide a too light and not a deep mastery. That could have been your problem in secondary school, one that leads to comprehension shock or difficulties in calculus and more generally in the first year of college. Bon Appetite.
