PLT GOAL STATEMENTWhat can we do

differently in our leadership skills in order to

1) have powerful conversations with our PLT members and

2) grow in our capacity to lead the implementation of the CCRS, through the application of best practices?

Levels of Cognitive Demand

High LevelDoing MathematicsProcedures with Connections to Concepts,

Meaning and Understanding

Low LevelMemorizationProcedures without Connections to

Concepts, Meaning and Understanding

Hallmarks of “Procedures Without Connections” Tasks Are algorithmic Require limited cognitive effort for completion Have no connection to the concepts or meaning that

underlie the procedure being used Are focused on producing correct answers rather

than developing mathematical understanding Require no explanations or explanations that focus

solely on describing the procedure that was used

Hallmarks of “Procedures with Connections” Tasks

Suggested pathways have close connections to underlying concepts (vs. algorithms that are opaque with respect to underlying concepts)

Tasks often involve making connections among multiple representations as a way to develop meaning

Tasks require some degree of cognitive effort (cannot follow procedures mindlessly)

Students must engage with the concepts that underlie the procedures in order to successfully complete the task

“Procedures with Connections” Tasks

Using a 10 x 10 grid, identify the decimal and percent equivalent of 3/5.

EXPECTED RESPONSE

Fraction = 3/5

Decimal 60/100 = .60

Percent 60/100 = 60%

Hallmarks of “Doing Math” Tasks There is not a predictable, well-rehearsed pathway

explicitly suggested Requires students to explore, conjecture, and test Demands that students self monitor and regulated

their cognitive processes Requires that students access relevant knowledge

and make appropriate use of them Requires considerable cognitive effort and may

invoke anxiety on the part of students

Requires considerable skill on the part of the teacher to manage well.

“Doing Mathematics” Tasks

Shade 6 squares in a 4 x 10 rectangle. Using the rectangle, explain how to determine each of the following:

a) Percent of area that is shaded

b) Decimal part of area that is shaded

c) Fractional part of the area that is shaded

a) Since there are 10 columns, each column is 10% . So 4 squares = 10%. Two squares would be 5%. So the 6 shaded squares equal 10% plus 5% = 15%.

b) One column would be .10 since there are 10 columns. The second column has only 2 squares shaded so that would be one half of .10 which is .05. So the 6 shaded blocks equal .1 plus .05 which equals .15.

c) Six shaded squares out of 40 squares is 6/40 which reduces to 3/20.

ONE POSSIBLE RESPONSE

The Importance of Student Discussion

Provides opportunities for students to:

Share ideas and clarify understandings Develop convincing arguments regarding why

and how things work Develop a language for expressing

mathematical ideas Learn to see things for other people’s

perspective
