2. Mathematics and StatisticsProgressions in Probability Ngatea Teacher Day, June 15thHauraki Plains College Jim Hogan, Sandra Cathcart, Brenda McNaughton Faculty of Education Team Solutions, Auckland University

3. Objectives de jour • To enhance teacher knowledge and understanding of probability progressions to senior levels • To experience a selection of probability activities for use in the classroom to enhance pedagogy of NZC • To develop teacher capability for scheme design

4. War plan • 20 minutes on progression activity • 20 minute report back • 30 minutes on activities • 10 minutes scheme design ideas • 10 minutes feedback • Total 90 necminits

5. Progressions • Use the A3 photocopies sheet as a resource. • List main idea(s) at each level • Describe one key activity/learning event for that level • 20 minits

6. Level 1 Probability • The key idea of probability at level 1 is beginning to explore chance situations.

At level 1 students are exploring games of chance that they play and outcomes from statistical investigations.  They are discussing the different outcomes that are possible.

Students are developing early probability language and describing outcomes.  For example an outcome is certain, possible, impossible or an outcome always happens, never happens, sometimes happens. • Learning Activity • Lonely Pig (NZMATHS) • Describing events with own probability language (will, won’t, might). Using a dice. • “Dad will not be bringing me to school tomorrow. He never brings me to school.”

7. Level 2 Probability The key idea of probability at level 2 is beginning to recognise that some events are more likely than others in chance situations.

At level 2 students are recognising the different likelihood of outcomes for games of chance that they play.  They are describing outcomes from statistical investigations, for example, children in our class were more likely to have bananas in their lunch today than any other fruit (15/24 children had bananas in their lunch).

Students are developing more sophisticated nuances with probability language to describe outcomes, for example, more likely, less likely. • Learning Activity • Addition facts using two 0-9 dice • Memory card game.

8. Level 3 Probability • At level 3 students are beginning to explore one-stage chance situations, for example tossing a drawing pin, throwing a die from a board game, tossing or spinning a coin, rolling a pencil, or tossing a “pass the pigs” pig.  They are listing possible outcomes for situations.  Students are recording their results and plotting frequencies of outcomes.  Students are comparing their experimental results with others in the class, acknowledging that results may vary.  Students are recognising that in some chance situations outcomes are not equally likely, for example tossing a pig or drawing pin. • Key Skill • Systematic recording of outcomes. • Recognising fair and unfair games • Learning Activity • Dicey Differences Year 6 Nat STD • Random walking in 2 dimensions. • Battleships, Yahtzee (1 – 6), Numahtzee (0 – 9)

9. Level 4 Probability • Key idea • Using simple fractions and ratios to describe probabilities. Independence of events. Writing and talking about this. • Key Skill • Connecting 9 out of 10 as 90% = 9/10 =0.9 • ½ is guessable. 1/10 is much harder than 1/6. • Learning Activities • Card collecting. How many do you need to buy? • Dicey Differences Year 8 Nat STD

10. Level 5 Probability • Key idea • Long run probability. Experimental v theoretical probability expectations. Everyday event chance. • Key Skill • Using random numbers, tree diagram, logic. • Learning Activity • Inventing games of chance • Random walks • Chance in Monopoly

11. Level 6 Probability • Key idea • Random selections. Sample size matters. Independence of events. • Key Skill • Sample size of about 30 is a good choice. • Conditional prob using tree diagrams • Learning Activity • Graphing the long probability of outcome like tossing a coin.

25. Who uses probability? • Scientists, social scientists, researchers, • Quantum Mechanics involves “probability density functions” which deals with the likelihood of where one particle might be. • Insurance, actuaries, teachers.

26. SCHEMES and THINGS On to more serious things. Rule 1 of scheme writing • There are no rules. • It is all about what works for you.

27. Scheme Is not a lesson plan. It is an outline of how the learning for a particular topic is going to be approached - for your students - with your resources - in your classroom/school.

28. An example A n NZC scheme. Mine actually! The lesson plans are in the plan book, if required, and are probably best written after the lesson.
