FRACTIONS

THE KEY TO SUCCESS AT SCHOOL AND IN EVERYDAY LIFE


Facts

FACTS

Fractions, percentages and decimals are keystones for progress and success in:

* Everyday life, e.g. VAT interest, profit, loss, tax, mark-up, etc.

  • At school, e.g. Mathematics, Physical Science, Economics, Accounting, etc.

  • Small Business and Industry workplace. (Mechanics, Technicians, Entrepreneurs, etc.)


Daily newspaper and other reports leave no doubt as to

Daily newspaper and other reports leave no doubt as to:

  • The poor standard of education and mathematics in particular;

  • The desperate need for urgent intervention

    to improve the situation.

More findings from a hrsc survey

MORE FINDINGS FROM A HRSC SURVEY

Findings by HSRC in 2004 (35 000 gr. 6 -

learners):

  • Average 27% in Mathematics;

  • Available resources play an important role in

    performances;

  • 8 out of every 10 grade 6 learners cannot do

    sums;

  • Only 4 out of ten proficient in the language of

    instruction

The answer fraction wizz

THE ANSWER: FRACTION WIZZ

  • Fun for kids;

  • Practical and hands-on;

  • Concrete experience of abstract principles;

  • A teacher’s dream.

  • Learners learn and understand while they play.

Fractions

Two halves equal a unit/”whole”/one.


Fractions

Three thirds equal

a “whole”

(Fit into unit slot)


Fractions

12 beads the “whole”

in the unit cup

(A third of

twelve is four)

Divide the 12 beads

equally among the

three thirds-cups.

In short

In short:

  • All basic principles can be practically experienced;

  • Abstract concepts concretized for better conceptualization;

  • The result: UNDERSTANDING!!!!


Other features

OTHER FEATURES

  • Ideal for group work (6 learners per group, 3 using base and 3 using lid to establish principles.) Each learner completes own workbook.

  • Only six or seven sets necessary per school. Transparent lid makes control easy.

  • Relevant fraction, decimal and percentage displayed on base of each piece. (Also the Braille configurations to aid blind learners.)


Fractions

Each learner has a

workbook leading them

through the stages

systematically.

EASY TO USE GUIDE / WORKBOOK


Ms naledi pandor s reported comments on mathematics

MS. NALEDI PANDOR’S REPORTED COMMENTS ON MATHEMATICS:

  • Marks are higher when learners interact with teachers, when they work together and use educational material;

  • Teachers obviously need adequate resources, and where it’s not available, learners perform poorly;

  • Resources make a difference, emphasizing an education policy aimed at the poor.


Comments from teachers using the fraction wizz

COMMENTS FROM TEACHERS USING THE FRACTION WIZZ

  • “Invaluable, indispensable …..I cannot imagine teaching without it in future!”

    - Mr. Frans Massyn (Fichardtpark Primary School).

  • “As a result of the concrete, visual nature of this model, learners are mastering the skills and understanding of fractions much easier while having lots of fun.”

    - Ms. P. van Tonder (Eunice Primary School)

  • The Fraction Wizz … “will replace frustrating hours of battling to understand fractions with hours of fun.”

    - Prof. Deon de Beer (CUT)


Fractions

Bringing understanding to all learners.


The best gift you can give anyone is to help him her to acquire skills

THE BEST GIFT YOU CAN GIVE ANYONE IS TO HELP HIM/HER TO ACQUIRE SKILLS.


Closing remark

CLOSING REMARK

“IMPROVE PROFICIENCY IN FRACTIONS, AND VAST IMPROVEMENT IN THE LEVEL OF SCHOOL MATHEMATICS WILL

FOLLOW.”

- Mr. G G Kriel
