Basic 6 Mathematics Term 1 Week 11 Lesson Plan

Review learners understanding of the previous lesson through questions and answers. Engage learners with a short mental mathematics activity to prepare them for the lesson.

Guide learners to multiply a whole number by a fraction, e.g. 5 × 2 3 or finding five two-thirds means 2 3 + 2 3 + 2 3 + 2 3 + 2 3 = 10 3 = 3 2 3 To multiply a whole number by a mixed fraction (e.g. 3 × 2 2 3 ) one can multiply the whole number by the whole number and then whole number by the fraction and add the products or change the mixed fraction to improper fraction and multiply; i.e. 3 × 2 2 3 = (3×2) + (3 × 2 3 ) = 6 + 2 3 + 2 3 + 2 3 = 6 + 6 3 = 24 3 = 8 To multiply a whole number by a fraction (e.g. 3 × 2 2 3 ) first change all into common fractions, then multiply the numerators separately and multiply the denominators separately and simplify; i.e. 3 × 2 2 3 = 3 1 × 8 3 = 3 X 8 1 X 3 = 24 3 = 8 Assessment: Have learners practice with several examples To multiply a fraction (i.e. common or mixed) by a whole number e.g. 4 4 5 × 5 first change all into common fractions, then multiply the numerators separately and multiply the denominators separately and simplify, i.e. 4 4 5 × 5 = 24 5 × 5 1 == 24 x 5 5 x 1 = 120 5 = 24 1 = 24. Assessment: Have learners practice with several examples Use mapping diagram to explain the concept of proportion as equal fractions or equivalent ratios. example: The mapping diagram shows that the ratio of number of hens to number of eggs are equal, hence the number of hens is proportional to the number of eggs. Assessment: Give learners mappings to identify those that are proportional and those that are not Guide learners to work out proportion in given contexts and use them in solving problems; e.g. 200 bottles of equal capacity hold 350 liters of water. How much water does each bottle hold? If 200bottles=350litres Then 1bottle= 350liters 200 bottles = 1.75 liters Therefore each bottle holds 1.75litters of water Assessment: Have learners practice with several examples For this activity, learners use bottle tops in two colours, beans and maize grains and exercise books to build and compare concrete ratios before recording equivalent ratios and solutions.

Ask learners to tell you what they have learnt and what they will like to learn in the next lesson Give learners individual or home task. Ask learners to tell you what they have learnt and what they will like to learn in the next lesson Give learners individual or home task.
