The sage on the stage
Teacher-Centered
Guide on the Side, not the sage on the stage
A Danger of Social Constructivism
Student-Centered
Allows God’s absolute truth in mathematics to speak for itself
Uses many of the same pedagogies as student-centered
Content-Centered
The next classroom observation, have someone draw arrows on your seating chart for all discourse that occurs.
Are all questions directed to you? Do you repeat student questions?
What is the center of your classroom?
Logical Thinkers Problem Solvers
Problem-Based Learning
World
Any comments or questions? Reinforce the next day with a Frisbee and
tape measure
Pi Activity
Pattern Blocks
Given the three block patterns, identify how the pattern is growing from Case 1 to Case 3.
Represent this growth
How did you approach this?
Pattern Blocks
Memorization Procedures Without Connections Procedures With Connections Doing Mathematics
Stein, Smith, Henningsen, and Silver 2000, p. 16
Four Levels of Cognitive Demand
Reproducing a fact learned from memory Not ambiguous No connection to concepts or underlying
meaning
2 + 7 =Represent ¼ as a decimal and a fraction
Four Levels of Cognitive DemandMemorization
A recipe to follow Low cognitive demand Little ambiguity Focused on the answer, not the process
Davis wants to tile his rectangular room which is 8 feet by 10 feet. How many square feet of tile will he need to purchase?
Four Levels of Cognitive DemandProcedures without Connections
Focus on the procedure to create deeper understanding
A path to follow may be suggested Often multiple representations are used Requires mental effort
Using base-ten blocks, show that .17 is less than .2
Four Levels of Cognitive DemandProcedures WITH Connections
Complex thinking N0 path or recipe to follow Students need to access necessary
knowledge Cognitively demanding
In my bag of candy ½ of the pieces are red, 1/3 are blue, the remaining 21 are white. How many pieces are in the bag?

How would you categorize the pi activity? How about the pattern block activity

Can Differentiate Instruction based on the question
Students who perform best on project-based problem solving were in classrooms in which tasks were implemented at high levels of cognitive demand Leutzinger, L. ICTM Journal, 2010
Good teaching demands a blend of all four levels
Four Levels of Cognitive Demand
What could you do with newspapers Work with place value –Find Purchase car
Give students a large amount of frequent flier miles to plan a trip around Europe with. What topics could you cover with this?
What can you do with census data?Kristin Kanaskie 2011 Fall ICTM Journal p. 4

Visit a creek Estimate depth Estimate water flow (Math’s Teacher, May 2012)
A bag of oranges Volume Peel it to find surface area (Math’s Teacher, Oct.
2011) Stack oranges for space
Ideas
Turning everyday living activities into math Have students record, survey, analyze, and
collect data: number of texts send/received a day hours of sleep hours of T.V. hours of favorite activity...
Students can collect data in a journal and expand using graphs and calculations

How much water do you use in the shower? How long does it takes to fill up a gallon Average amount of time spent in the shower (Dan Meyer)
Exploring surface area using cheese blocks of same volume but different surface areas Which takes longest to melt in the microwave (Dan Meyer)
Using a bike to look at speed, gears for ratio and proportion. Using plastic cups... how many cups will you have to stack
to be the height of your teacher (Dan Meyer) Three doors with a prize, stay with your same choice or
switch? The Monty Hall problem
