BUDGET FOR A GRADE 4 BRAAI

 INCOME ACTUAL INCOME Money earned EXPENDITURE Cost in R FINAL TOTAL

Now remember to take the amount spent away from the “Income”. Is there enough

money for paper plates and cups?

## Test your progress

Let’s have another look at how you’re coping.

1. Round off to the nearest:

 Ten Hundred Thousand 1 387 925 4 813 6 492 9 509

2. In each sum, estimate the approximate answer by rounding off the numbers to the nearest hundred. You do not need to calculate the exact answer:

• 7 462 + 2 948
• 9 476 － 4 508

3. Money

• How many 1c pieces are there in R50?
• How many 5c pieces are there in R50?

4. Calculate, writing down all your steps clearly:

• 5 907 + 3 754
• 6 098 － 3 274
• 1 234  768  630  266

CALCULATORS AND WORD SUMS

You may use your calculator to find the answers in this section.

5. Read this sum carefully and answer the questions. Write down some proof to show how you reached each answer.

A professional gardener, Mr Gouws, prunes 765 rose-bushes in July. Mr Greg prunes 648 rose-bushes in the same month. In the first week of the next month Mr Gouws prunes another 165 bushes, while Mr Greg prunes another 261 bushes. Then in the second week of August Mr Greg prunes 87 more bushes while Mr Gouws prunes 184 bushes.

• In July how many more bushes did Mr Gouws prune than Mr Greg ?
• At the end of the first week in August was Mr Greg catching up to Mr Gouws? Give reasons to support your answer.
• Altogether, who pruned the most rose-bushes?
• How many bushes did both men prune altogether?

## Assessment

 Learning outcomes(LOs) LO 1 Numbers, Operations and RelationshipsThe 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 standards(ASs) We know this when the learner: 1.6 solves problems in context including contexts that may be used to build awareness of other Learning Areas, as well as human rights, social, economic and environmental issues such as:1.6.1 financial (including buying and selling, and simple budgets).
