 PRESENTATION TEACHER’S ACTIVITY PUPIL’S ACTIVITY STEP 1MENTAL MATHS The teacher begins the lesson with some mental calculationsCalculate1 2 × 42 5 × 4  3 8 × 4  4 3 × 45 6 × 4  6 10 × 47 1 × 4  8 7 × 49 9 × 410 4 × 4 Pupils respond and participate STEP 2CONCEPTDEVELOPMENT The teacherUse your large strip of paper made from flip chart paper.• Folds the strip in half and then in half again.• Open the strip and trace the fold lines with a pencil.• Pastes the strip on the board. • Asks: How many parts are there? (4)• Says: Let’s check whether all 4 parts are equal or not.• Cuts the strip along the lines and put the pieces on top of each other.• Says: They are all the same size. That means they are equal.• Pastes all 4 parts on the board to remake the original strip.• Explains: When you make four equal sized parts from one thing, you call each part a (one) quarter of the original thing.• Writes ¼ and ‘one quarter’ on the board.• Let the learners read ‘a quarter’ and write ¼ several times in the air.• Lets the learners write ¼ in their classwork book 4 times.• Write ¼ in each part of the strip on the board.• Explains: Numbers like ½ and ¼ are called ‘fractions’.• Lets the learners say the word ‘fractions’ several times. CLASS ACTIVITYThe teacher• Gives each learner a strip of paper that you prepared using scrap A4 paper.• Lets the learners fold the strip in half twice, as you did in Activity 1.• Lets the learners open the strip and trace the fold lines with a pencil.• Asks: How many equal parts do you see on the strip? (4)• Asks: What do we call each part of the strip? (one quarter)• Lets the learners write ¼ in each part of the strip.• Explains: We call the original strip ‘a whole’.• Lets the learners say ‘a whole’ several times.• Lets the learners paste their strips into their classwork books. Pupils pay attention and participate STEP 3CLASS-WORK Shade ¼ of each shape. Pupils attempt their class work STEP 4HOME-WORK I cut an apple into quarters. How many children can get the same size piece of the apple? The pupils writes it in their homework book STEP 5SUMMARY The teacher summarizes by reminding the pupils that in today’s lesson we have learnt what a quarter is.
