## Content

### To use strategies to check solutions [LO 1.11]

1. We have now investigated a few techniques to calculate answers. We encounter problems like those below every day. If we are unable to solve them, we will not be able to do calculations with much confidence! Form groups of three and try to solve the following problems. Your educator will supply the paper you need.

1.1 Dimitri and his friends decided to go to the “Bites-and-Bits” restaurant.

Sandwiches:

Cheese R9,99

Ham and cheese R12,99

Egg R11,99

Tomato, ham and cheese R15,99

Chicken R15,99

Beverages:

Coke, Fanta, Sprite, Cream Soda R4,95

Milkshake: Strawberry, Banana, Chocolate R8,95

• Dimitri orders a ham and cheese sandwich and a strawberry milkshake.
• Vusi orders a chicken sandwich and a Coke.
• Nancy orders an egg sandwich and a chocolate milkshake.
• If Dimitri offers to pay the bill, how much will he have to pay?

1.2 Mr Zuma, Principal of the Perseverance Primary School, decides to replace the old floor tiles in the hall with new ones. The tiles are delivered and he asks the learners to carry them into the hall.

• The Grade 7’s carry 1 893 tiles; the Grade 6’s carry 976 tiles, the Grade 5’s 824 tiles and the Grade 4’s 769 tiles to the hall. How many tiles have been carried to the hall?

2. Explain your group’s method of calculation to the class.

3. Compare your methods. How do they differ?

## Assessment

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 1.6: We know this when the learner 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;

Assessment Standard 1.10: We know this when the learner uses a range of techniques to perform written and mental calculations with whole numbers;

Assessment Standard 1.11: We know this when the learner uses a range of strategies to check solutions and judge the reasonableness of solutions.
