Swift Current Feb. 16, 2012
Where are we at: • 30 level curriculum • Calculus 30 • Modified • Other questions
Inquiry Based Learning • http://www.youtube.com/watch?v=RLVTV-vXJBg • http://www.youtube.com/watch?v=sLQPXd8BiIA&feature=related
Inquiry • Changes how students and teachers relate to one another • How students relate to each other • How they relate to the material • How they relate to authority
Challenges • Past, present and future communities that contribute to current thought • What is ‘appropriate mathematical learning’ as viewed by parents, teachers and students? • How do we change and grow pedagogically? Learn from and with teachers.
Little room and flexibility in curriculum with the number of topics that need to be covered
Change • From explaining to justifying • What are student interested in learning about? What questions do they have? • Respect personal sense-making but still challenge an inefficient strategy and reach a consensus on what efficient strategy would look like
Negotiate meaning and maximize the mathematical inquiry • Summarize the learning and co-determine the most reasonable and efficient strategy
Geoboard • How many squares can you make on the geoboard?
Geoboard • How many squares can you make on the geoboard? • How many squares can be made on an N by N board?
Triangles • You have an infinitely large sheet of dot paper. What size triangles can you draw? • Can you draw triangles with area 1, 2, 3,….square units? 1.5? • How many triangles of area 2? Can you create families or groups for these triangles? • Smallest area?
Quadrilaterals • Can you make a quadrilateral with exactly: • 4 equal sides, 3 equal sides, 2 equal sides • 4 non-equal sides, 3 non-equal sides, 2 • One pair of perpendicular lines • One pair of parallel lines • Two pairs of perpendicular lines • If you cannot find one, explain why
What is the goal of the lesson? • The questions should be leading to the end goal. • Think of possible explanations/solutions/problems that student may encounter working on the question. • Easier to summarize student work if they are working toward a clear goal
Geoboard • How many regular polygons can you create on the geoboard…using both sides?
http://www.youtube.com/watch?v=KJ_d3LiiLYU • What do you see when you watch this trailer? • What mathematics do you see? • http://sciencedemonstrations.fas.harvard.edu/icb/icb.do?keyword=k16940&pageid=icb.page80863&pageContentId=icb.pagecontent341734&state=maximize&view=view.do&viewParam_name=indepth.html#a_icb_pagecontent341734 • http://www.youtube.com/watch?feature=player_detailpage&v=yVkdfJ9PkRQ
Curriculum Connections • FM10.2 • PC20.2 • WA30.4
Napkin problem • Three triangle investigation • Investigate the three triangles formed.
Questions • When was the BMI developed? • When were the age and height tables that represent the growth of children made? • How do they collect the data that determine the weight and height of a 4 year old? • What does it mean to be in the 95th percentile? • When, why and who would reference percentile rank?
Group Summary • Move beyond “show and tell” • Challenge weaknesses and strengths of solution • Reasonable and efficient
Block it out • http://www.youtube.com/watch?v=Pty1KFfDkHM
Four Block Problem • What strategies did you use • Four cubes problem – 2 • http://www.youtube.com/watch?v=nv7cueW-_Fo&feature=relmfu
A Russian Fable • Take three blades of grass, folded in two, and hold them in your hand so that the six ends are hanging down. • Tie the ends together in pairs If on release, a large loop is formed, you will __________
Bungiebarbie • How many elastics would it take to bungiebarbie over the balcony?
Guidelines I do not want trial and error so I will limit each group to 5 elastics before we measure the height of the balcony. Once I give you the height of the balcony you have 5 minutes to determine the number of elastics you will need to bring barbie as close to the floor as possible without hurting barbie.
Illuminations • http://illuminations.nctm.org/LessonDetail.aspx?id=L646
Class discussion • What procedure did you use. • Justify to the group why you deserve the reward.
Pedagogical Questions • Will my students be able to solve it? • What kinds of mathematical ideas does the problem involve? • Will the problem help me learn about my students’ mathematical thinking
Mathematical Questions • Is the problem interesting? • Are there good techniques for solving it? • Does it relate to other areas of mathematics? • Crespo & Sinclair 2008
