We Are Learning To . . .
1. Further our understanding of the cognitive demands of mathematical tasks.
2. Explore the factors associated with the decline or maintenance of cognitive demands.
3
Success Criteria
You will be successful if at the end of the session you can– identify the cognitive demand levels of
mathematical tasks– describe the factors that lead to the maintenance or
decline of high-level cognitive demands during setup and implementation of mathematical tasks.

Cognitive Demands…
“The kind and level of thinking required of students in order to successfully engage with and solve the task.”
Stein, Smith, Henningsen, & Silver, (2000)

The Fencing Task Ms. Brown’s class will raise rabbits for their spring science fair.
They have 24 feet of fencing with which to build a rectangular rabbit pen to keep the rabbits.
a) If Ms. Brown’s students want their rabbits to have as much room as
possible, how long would each of the slides of the pen be?
b) How long would each of the sides of the pen be if had only 16 feet of fencing?
c) How would you go about determining the pen with the most room for any amount of fencing? Organize your work so that someone else who reads it will understand it.

Math Task
Cognitive Demand Level
Individually work on the problem
Share your problem solutions at your table
Using the handouts from December, determine the cognitive demand level of the math task.

Four Levels of Cognitive Demands in Mathematical Tasks
Low Level Cognitive Demands
Memorization Tasks
Procedures Without Connections to understanding, meaning or concepts Tasks
High Level Cognitive Demands
Procedures With Connections to understanding, meaning or concepts Tasks
Doing Mathematics Tasks

Reading: “Using Cognitively Complex Tasks in the Classroom”
Individually read pages 24-26.
Reading Lens: In what ways do teacher actions during the setup and implementation phases impact the cognitive demands of mathematical tasks?
10
Mathematical Tasks Definition
“…not only the problems written in the textbook or a teacher’s lesson plan, but also the classroom activity that surrounds the way in which those problems are set up and actually carried out by teachers and students.”
Stein, Smith, Henningsen, & Silver, (2000)
11
Tasks in the Classroom
Setup Phase: Teacher communicates to students expectations- what to do, how to do it, and with which resources.
Implementation Phase: From the time students begin to work until the next task begins.

Cognitive Demands and Features
Task Level of Cognitive Demand
Explanation of Categorization

Fencing Problem
Doing Mathematics There is no pathway suggested by the task. The focus is on looking for the underlying mathematical structure.
•Requires an explanation•Involves multiple steps•Uses a diagram

Group Reading Activity
Table Group Readings1~ “Maintenance of high-level cognitive demands”
2~ “Decline into procedures”
3~ “Decline into unsystematic exploration”
4~ “Decline into nonmathematical activity”
15
Group Poster Activity
1~Maintenance 2~Procedures3~Unsystematic 4~ Nonmathematical
Individually read your section
As a group discuss the highlights of the section
Create one poster per section capturing the important points (What Teachers do/Students do)
16
Poster Presentations
In your notebook create a graphic organizer for note taking
Maintenance of high-level cognitive demands
Decline into procedures
Decline into unsystematic exploration
Decline into nonmathematical activity

December Homework
Mathematical Tasks Discussion
Each person presents one of their tasks.
Justify why it is Doing Mathematics or Procedures with Connections
As a table group, discuss the possible factors involved in maintaining or declining the level of cognitive demands in the set up or implementation phases of the math task in the classroom.

“When teachers take the opportunity to analyze the tasks, they become more alert to the potential for slippage between intentions and actions in their teaching.
Stein, Smith, Henningsen, & Silver, (2000)

Success Criteria
You will be successful if at the end of the session you can– identify the cognitive demand levels of
mathematical tasks– describe the factors that lead to the maintenance
or decline of high-level cognitive demands during setup and implementation of mathematical tasks.
