 PRESENTATION TEACHER’S ACTIVITY PUPIL’S ACTIVITY STEP 1MENTAL MATHS The teacher begins the lesson with some mental calculationsCalculate1. __ x 10 = 502. __ x 10 = 303. __ x 2 = 124. __ x 2 = 205. __ x 10 = 606. __ x 10 = 907. __ x 2 = 188. __ x 2 = 149. __ x 10 = 7010. __ x 2 = 0 Pupils respond and participate STEP 2CONCEPTDEVELOPMENT The teacher • Writes the following information on the board.This is what people ordered at a restaurant on Friday night:10 hamburgers, 5 hot dogs, 15 pap and meat, 10 rice and chicken and 20 curry pies.• Draws a frequency table on your whiteboards/scrap paper to show this data.• Reminds learners how to use tally marks – in groups of five. For each item draw a short line – do this for four items. The fifth count is marked by crossing out the first four and making a bundle of five. Then start with a new bundle for the next five items, and so on.The tally table for the restaurant orders was as follows:(work through this with the class counting up all of the tallies).• Look at your table and answer these questions – and make up other similar questions if there is time:−− How many people chose rice and chicken? ___ (10)−− How many people chose curry pie? ___ (20)−− What is the most popular meal? ___ (Curry pies)−− What is the least popular meal? ___ (Hot dogs)−− How many meals were ordered? ___ (60)−− What is the second most popular meal? (Pap and meat)−− What is the difference in orders between people who chose pap and meat and people who chose hotdogs? (10)−− What is the difference in orders between the most popular and the least popular meal? (15) CLASS ACTIVITYThe teacher• Draw and complete a bar graph with the learners on the board. Use the information from the table on theirwhiteboards/scrap paper: Pupils pay attention and participate STEP 3CLASS-WORK Use the bar graph on Favourite pets to answer the questions that follow1. Which 3 pets are represented in the bar graph?2. Which pet is the most popular?3. Which pet is the least popular?4. What is the difference in number between learners who like dogs and learners who like birds?5. Draw a pictograph to represent the data which is in the bar graph. Pupils attempt their class work STEP 4HOME-WORK Use a bar graph to show the data in the table below. Remember to give your graph a title and to label the axes. STEP 5SUMMARY The teacher summarizes by reminding the pupils how to Represent data in a pictograph with one-to-one correspondence and bar graph.She marks their class works, makes corrections where necessary and commends them positively
