Peter Liljedahl Teaching to the New 10C Curriculum
Activity #1 How tall is Connor?
Learning Outcomes – pg. 19 • Solve problems that involve linear measurement, using: • • SI and imperial units of measure • • estimation strategies • • measurement strategies. • Apply proportional reasoning to problems that involve conversions between SI and imperial units of measure.
Learning Outcomes – pg. 24 • Interpret and explain the relationships among data, graphs and situations. • Demonstrate an understanding of slope with respect to: • • rise and run • • rate of change
Learning Outcomes – pg. 25 • Describe and represent linear relations, using: • • words • • ordered pairs • • tables of values • • graphs • • equations. • Determine the characteristics of the graphs of linear relations, including the: • • slope
Mathematical Processes – pg. 6 Students MUST encounter these processes regularly in a mathematics program in order to achieve the goals of mathematics education. All seven processes SHOULDbe used in the teaching and learning of mathematics. Each specific outcome includes a list of relevant mathematical processes. THE IDENTIFIED PROCESSES ARE TO BE USED AS A PRIMARY FOCUS OF INSTRUCTION AND ASSESSMENT.
Nature of Mathematics – pg. 10 Mathematics is one way of understanding, interpreting and describing our world. There are a number of characteristics that define the nature of mathematics, including change, constancy, number sense, patterns, relationships, spatial sense and uncertainty.
Goals for Students – pg. 4 Mathematics education must prepare students to use mathematics confidently to solve problems.
The New Curriculum Still about: • specific outcomes • achievement indicators Also about: • goals for students • mathematical processes • nature of mathematics CONTEXT CONTENT
Local Discussion • What is the value AND feasibility in considering both the specific outcomes and the front matter (goals for students, mathematical processes, nature of mathematics) within our teaching? • What are the consequences of not doing so? 15 minutes

Activity #2 A boy has $80 to buy 100 budgies. Blue budgies cost $3 each, green budgies cost $2 each, and yellow budgies cost $0.50 each. If he want to ensure that he has at least one budgie of each colour, how many of each colour does he need to buy? Is there more than one answer? How do you know you have ALL the solution?
Linking ACTIVITY to CURRICULUM • 2-3 people identify in what ways this activity meets: • specific outcomes • achievement indicators • 2-3 people identify in what ways this activity meets: • goals for learning • mathematical processes • nature of mathematics SHARE and COMPARE
What is attainable? How many budgies? MATHEMATICAL THINKING
Building a culture of THINKING START STOP / reduce answering stop thinking questions levelling thinking that a lesson is about generating notes assuming that students can't stop emphasizing the use (and creation) of pre-requisite knowledge using assessment as a stick • giving thinking questions • using group work • randomizing groups • using vertical work surfaces • talking about thinking strategies (different from solution strategies) • assessing thinking • evaluating what you value
Building a culture of THINKING • WATCH THE BUILDING A CULTURE OF THINKING WEBINAR! • start on day 1 • 6 consecutive tasks • non-curricular • no pre-requisite knowledge needed • interesting • random groups • working on feet • take pictures
Local Discussion • How do we live with the possibility that some of these activities bring together curriculum from many different topics within 10C? 15 minutes

Activity #3 How many UPRIGHT triangles are there ... base = 4 ... if the base = n?
How many UPRIGHT triangles? base size 1 = 10: 1+2+3+4 base size 2 = 6: 1+2+3 base size 3 = 3: 1+2 base size 4 = 1: 1 triangular numbers # of triangles = the sum of the first n triangular #'s
How many UPRIGHT triangles? tn= 1 + 2 + 3 + ... + n (triangular # n) tn+ tn-1= sn (square # n)
How many UPRIGHT triangles? base size 1 = 10: 1+2+3+4 base size 2 = 6: 1+2+3 base size 3 = 3: 1+2 base size 4 = 1: 1 triangular numbers # of triangles = the sum of the first n triangular #'s
How many UPRIGHT triangles? Tn= t1 + t2 + t3 + ... + tn (tetrahedral # n) Tn= Tn-1+ tn Tn+ Tn-1= Pn (pyramidal # n)
How many UPRIGHT triangles? Pn = n(n+1)(2n+1)/6 1 n n+1 n
How many UPRIGHT triangles? Tn= Tn-1+ tn→ Tn-1= Tn- tn Tn+ Tn-1= Pn→ Tn+ Tn- tn= Pn→ 2Tn- tn= Pn Pn= n(n+1)(2n+1)/6 2Tn– n(n+1)/2= n(n+1)(2n+1)/6 Tn= n(n+1)(n+2)/6 SHAZAM!
How many UPRIGHT triangles? Tetrahedral Numbers
Linking CURRICULUM to ACTIVITY • Where did this question come from? • the exercises intended for the end of a lesson • Where do I use it? • at the beginning of the lesson • Do the students figure out the problem on their own? • most figure it out to some level – few to the final formula • Do they struggle with it? • definitely • So, why do it? • they learn from their struggles • my lesson on it has more meaning to them • my lesson is more about formalizing the learning that has already happened • it is normal within my classroom UPSIDE DOWN LESSON
Upside Down Lesson – 10C review: sin is the y-coordinate cos is the x-coordinate ask: If sin t= 0.5, 0o < t≤ 360o, find t.
Upside Down Lesson – 10C try: • If sin t = -0.8, 0o < t ≤ 360o, find t. • If sin t = 1.1, 0o < t ≤ 360o, find t. • If cost = 0.5, 0o < t ≤ 360o, find t. • If cost = -0.65, 0o < t ≤ 360o, find t. • If cost = 1.0, 0o < t ≤ 360o, find t. • If sin t = 0.7, 0o < t ≤ 720o, find t. • If tan t = 1, 0o < t ≤ 360o, find t. • If tan t = -0.5, 0o < t ≤ 360o, find t.
Local Discussion • What are YOUR challenges in making a rich task out of something as simple as: If sin t= 0.5, 0o < t≤ 360o, find t. 15 minutes

How will we know its working? Your behaviour on the tasks – positive • intrinsic motivation • self selected audience • my obvious charm • my careful selection of the task • my introduction of the task • your trust in me • engaged • found solutions • shared • helped • persevered
How will we know its working? Your behaviour on the tasks – negative • lack of intrinsic motivation • inherent anxiety • fatigue • distracted • inappropriate task • wrong set-up • too much/little time • impression I will give answer • never engaged • bored • tried but gave up • checked email • socialized • waited • left
How will we know its working? Your behaviour on the tasks – a priori • end of year • coaching • report cards • easily accessible chairs • not Dan Brownesqueenough • wrong title • wrong topic • didn't come • came late • sat in the back • sat alone
How will we know its working? Different interpretations of behaviours: • intrinsic characteristics (you) • immediate influence (me) • contextual influence (the day) • outside influence (life)
How will we know its working? Different interpretations of behaviours: • intrinsic characteristics (you) • me as speaker • contextual influence (the day) • outside influence (life) I would have a source of constant feedback!
How will we know its working? Use the mirror that is your classroom: • students are sensible • student behaviour is sensible (at some scale) • student behaviour is a sensible reflection of our teaching • look for thinking • look for discussion • look for engagement • look for enjoyment always remember the soccer pitch
Local Discussion • What will you do to prepare for teaching 10C in September? 15 minutes
Question & Answer finish at 3:25
Final Word • Everything I have told you is guaranteed to fail unless YOU think it is important enough to make it work! • This is not a PANACEA! There are other dragons to slay (assessment, didactics, notes, practice, review)! • You will enjoy teaching in a THINKING classroom! • Your students will enjoy THINKING! • Your students will LEARN!
