1 MESSAGE TO TEACHERS: NOTE TO EDUCATORS:

2 Attached herewith, please fid suggested lesso plas for term 1 of MATHEMATICS Grade 12. Please ote that these lesso plas are to be used oly as a guide ad teachers are ecouraged to develop their ow learer activities to supplemet ad/or substitute some of the activities give here (depedig o the school eviromet, umber ad type of learers i your class, the resources available to your learers, etc). Lesso plaig is a ecessary exercise for each ad every idividual teacher however it helps whe teachers sometimes pla together as a group. This iteractio ot oly help teachers to uderstad how to apply the Learig Outcomes (LOs) ad Assessmet Stadards (ASs) but also build up the cofidece of the of teachers i hadlig the cotet usig ew teachig strategies. The Learig Outcomes for the other subjects with which oe ca itegrate have ot bee idetified. The other subjects with which possible itegratio ca be made have bee listed. The Lesso pla could therefore chage if the other subject/s, their LOs ad Ass could be clearly stated. Do ot forget to build i the tasks for the Programme of Assessmet ito your Lesso Plas. Stregthe your efforts by supportig each other i clusters ad share ideas. Good Luck with your edeavors to improve Teachig, Learig ad Assessmet.

6 LESSON PLAN: 4 Lesso Pla: Aalytical Geometry Number of Activities 3 Duratio: 4h30 Week 7 Date Cotext: Mathematical : Ivestigatio of space Lik with previous lesso: Distace formula betwee 2 poits, Radius perpedicular to the taget at poit of cotact, completig the square. KNOWLEDGE (K): Eq of the circle cetre at the origi ad ot at the origi. Fid the cetre & radius of a circle by completig the square. Determie the equatio of a circle. Calculate the equatio of a taget of a circle. SKILLS (S): Derive, calculatio, applicatio VALUES (V): Appreciatio ad sharig ideas. ACTIVITY 1 ACTIVITY 2 ACTIVITY 3 Activity Cotet Equatio of a circle Fidig the cetre ad the radius of the circle Equatio of the taget LO,s ad AS s (a) (a) (b) Learers are remided of the distace formula betwee 2 poits o a Cartesia plae i the form of a class exercise. The teacher presets a chart with oe circle at the origi ad the other oe ot at the origi. Learers are the asked to fid the distace P i both cases. Learers will first get the coordiates of poits P ad O. OP 2 = r 2 = (x-0) 2 + (y-0) 2 ad (xa) 2 + (y-b) 2 = r 2 The teacher further explais to learers the differece betwee the 2 circles. Examples from the textbook to fid the equatio of a circle are doe o the chalkboard. Class work is give to learers so as to fid the equatio of circle. I both cases, learers will be asked to work i groups. The teacher will be movig aroud guidig them where ecessary. More exercises are give as homework. Learers will be give the equatio e.g. x 2 +y 2 + 6x -8y -11 =0 the asked to group them accordig to the commo factors. They are the asked to complete the square for both x ad y with guidace of the teacher. Gettig to (x+3) 2 + (y-4) 2 = 36. They will be asked to determie the cetre ad the radius of the circle. The teacher will be helpig the groups comparig with the geeral equatio i.e. (x-a) 2 + (y-b) 2 = r 2. Where the cetre is (a;b) ad radius r From this, learers will idetify the cetre after completio of the square i.e. (-3; 4) ad r= 6. Learers will be give more exercises i class to do ad will be give more time to discuss ad teach each other i groups. Learers are asked the relatio betwee the radius ad the taget of a at the poit of cotact. The teacher explais to learers how to get the gradiet of the taget from AB perpedicular to PO where M AB *M PO = -1 Example to be doe o the chalkboard. Give a sketch learers will get the gradiet of OP which will be guided to get to the gradiet of the taget AB. M OP = -3/2 ad M AB = 2/3. Learers i groups will get the equatio of the straight lie AB usig the equatio of a circle. Learers will do differet exercises i groups with the help of the teacher.
