IntroductionSO2:Solve a range of everyday problems us<strong>in</strong>g estimation and calculations. (Round<strong>in</strong>goff and truncat<strong>in</strong>g, with or without calculator, comb<strong>in</strong>ation, separation,comparison, equalisation, shar<strong>in</strong>g and group<strong>in</strong>g.)1. Problem solv<strong>in</strong>g strategies are based on a correct <strong>in</strong>terpretation of the problemsituation.2. Estimates can be justified with<strong>in</strong> context.3. Calculations are per<strong>for</strong>med accurately.4. Calculations follow some <strong>for</strong>m of logical reason<strong>in</strong>g process, which ispresented clearly.5. Solutions are correct <strong>in</strong> terms of the context.SO3:Verify and justify solutions with<strong>in</strong> different contexts. (Solutions derived bylearners and by others.)1. The reason<strong>in</strong>g process is expla<strong>in</strong>ed clearly.2. Solutions are justified <strong>in</strong> terms of the context. (Appropriate and <strong>in</strong>appropriatesolutions.)3. Solutions are shown to be consistent with estimations and vice versa.SO4:Per<strong>for</strong>m operations on simple and complex numerical expressions. (Four basicoperations <strong>in</strong> all comb<strong>in</strong>ations. Expressions <strong>in</strong>volv<strong>in</strong>g exponents that can becalculated without a calculator. Operations to be per<strong>for</strong>med with and without acalculator.)1. Operations are per<strong>for</strong>med accord<strong>in</strong>g to the conventions govern<strong>in</strong>g the order ofoperations.2. Solutions are correct.SO5:Describe and compare count<strong>in</strong>g systems from different cultures. (Own, <strong>African</strong>culture other than own, one other.)1. Numbers are translated from one base system to another. (Base 2, 5, 10, and16.)2. Descriptions show understand<strong>in</strong>g of how count<strong>in</strong>g systems developed andtheir significance.3. Descriptions show examples of how the systems might have been used, andthe limitations of the system.xxi
