The learners must be able to:

1. identify and solve problems and make decisions using critical and creative thinking;

2. work effectively with others as members of a team, group, organisation and community;

3. organise and manage themselves and their activities responsibly and effectively;

4. collect, analyse, organise and critically evaluate information;

5. communicate effectively using visual, symbolic and/or language skills in various modes;

6. use science and technology effectively and critically, showing responsibility towards the environment and the health of others;

6. demonstrate an understanding of the world as a set of related systems by recognising that problem-solving contexts do not exist in isolation;

7. reflect on and explore a variety of strategies to learn more effectively;

8. participate as responsible citizens in the life of local, national, and global communities;

9. be culturally and aesthetically sensitive across a range of social contexts;

• Integration of Themes:
• A healthy environment: Many vehicles use our roads and these are a source of pollution. Discuss. Safety on the roads is essential. Learners must obey road rules and safety measures taken by the school and road authorities. Discuss how learners can be safe while walking / travelling to and from school.
• Plants and flowers make our environment pretty and attractive. Learners must know these should be protected and not destroyed.
• Inclusively: Man, animals and plants all rely on one another to survive. Discuss this statement and give examples.

• Vehicles are essentially part of the learner’s experience and through these activities of counting to 150, a graph determining distances and vehicles, and the extension of bonds of 16, are used.
• Up to 50 objects are estimated, grouped and counted.
• The multiplication tables of 2 is introduced and addition and subtraction of 6, 7, 8 and 9 included.
• Shapes are identified and sorted by colouring

Assesment

Learning Outcome 1: The learner will be able to recognise, describe and represent numbers and their relationships, and to count, estimate, calculate and check with competence and confidence in solving problems.

Assessment Standard 1.9: We know this when the learner performs mental calculations involving:

1.9.1 addition and subtraction for numbers to at least 20;

Assessment Standard 1.10: We know this when the learner uses the following techniques:

1.10.2 doubling and halving.
