BRAIN-TEASER!

During a competition, the Grade 5, 6 and 7’s tie. 21 cool drink cans are delivered to them at the school. Seven of the cans are completely full and 7 are half-full. Seven empty cans are also delivered.

How will you divide the cool drink among the three grades so that everyone gets the same amount of cool drink and cans? (Hint: make a sketch!)

TIME FOR SELF-ASSESSMENT

It is important for us to know how you feel about the section of the work that you have just completed. Evaluate yourself by placing a tick in the appropriate space:

I can estimate the quotient by rounding off the divisor and the dividend. (LO 1.10) | ____ | ____ | ____ | ____ | |

I can estimate the quotient by making use of doubling. (LO 1.10) | ____ | ____ | ____ | ____ | |

I can estimate the quotient by making use of multiplication. (LO 1.10) | ____ | ____ | ____ | ____ | |

I can predict the quotient by looking at certain patterns on my calculator. (LO 2.1) | ____ | ____ | ____ | ____ | |

I can divide correctly and determine a remainder, without using my calculator. (LO 1.11) | ____ | ____ | ____ | ____ |

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

**1.10.2: **long division.
