Parents or relatives ask tables
Write a tables test in class every day
Regularly play tables games (non-electronic, e.g. cards)
Errors are written out
Regularly play electronic computer games
Other

D. Write down a few reasons why a solution to this problem will have a positive effect on the lives of Grade 4 learners.

Possible solutions to the problem.

  • Parents or older relatives should do better consolidation at home.
  • Learners should write a tables test daily.
  • Design games to ensure consolidation in a playful manner.
  • Learners write out mistakes made in tests 50 times.

Assessment

Learning Outcomes(LOs)
LO 1
TECHNOLOGICAL PROCESSES AND SKILLSThe learner will be able to apply technological processes and skills ethically and responsibly using appropriate information and communication technologies.
Assessment Standards(ASs)
We know this when the learner:
investigates :
1.1 investigates the background context, the nature of the need, the environmental situation, and the people concerned when given a problem, need or opportunity set in a local context;
1.2 examines existing products relevant to a problem, situation or need.
1.3 investigates by performing simple practical tests relating to aspects of the technological knowledge areas (Structures, Processing, and Systems and Control);
1.4 during investigations, plans a strategy for collecting data and information.
design :
1.5 writes or communicates a short and clear statement or a design brief for the development of a product or system related to a given problem, need or opportunity;
1.6 lists product and design specifications and constraints for a solution to a given problem, need or opportunity.
1.7 generates at least two alternative solutions and annotates the ideas;
1.8 chooses possible solutions, gives sensible reasons for choice, and develops a chosen idea using graphics or modelling techniques;
make :
1.9 develops a plan.
1.10 chooses and uses appropriate tools and materials to make products by measuring, marking, cutting or separating, shaping or forming, joining or combining, and finishing different materials with some accuracy;
evaluates :
1.12 evaluates the product or system based on criteria linked directly to the design brief and some of the specifications and constraints, and suggests improvements or modifications;
1.13 evaluates the efficiency of the plan of action followed and suggests improving future plans.
