Presentation Transcript

Mathematical Practice:

Construct viable arguments and critique the reasoning of others.

- Build logical progression of statements to explore conjectures
- Recognize and use counterexamples
- Justify their conclusions and respond to other’s ideas using drawings, diagrams, actions

5th Walls With Windows

Mathematical Practice:

Model with mathematics.

- Solve problems in everyday life
- Write equation to describe a situation
- Solve a design problem
- Make assumptions and approximations to simplify a complicated situation
- Interpret results to see if they make sense in terms of the situation

Singing at the Ballpark- 4th

21 students need to get to the ballpark.

Each car will carry one adult and up to

4 students.

5 ¼ cars please?

Check for Reasonableness

You can’t leave someone behind!!!!

Mathematical Practice:

Use appropriate tools strategically.

- Use paper pencil, concrete models, ruler, protractor, calculator, spreadsheet, etc.
- Tools might also include choosing an appropriate mathematical strategy

Mathematical Practice:

Attend to precision.

- Communicate precisely with clear definitions
- State meaning of symbols
- Calculate accurately, efficiently, and use appropriate level of precision

Have a Clear Definition

Teacher comments on 2-4 tests: Why do the tasks use the word angle when our textbooks use “vertex”?

Words are tools for thinking

Not having words to use limits the mathematics we can think about. – Harold Asturias, Lawrence Hall of Science

Teacher comments: Why did you use the word “dimensions” on the 5th grade task box of cubes? Why didn’t you just ask for length, width, and height?

Cognitive Demand

- How many dimensions are there?

Mathematical Practice:

Look for and make use of structure.

- Discern pattern or structure
- See complicated things, such as algebraic expressions as single objects or as composed of several objects

5th- Box of Cubes- Structure

Making Sense of Structure

Seven most important words to transform education: How did you

Figure that out?

7th Grade Freezing in Fargo

- How many times colder is Wednesday Feb. 25th than Tuesday Feb. 3rd?
Almost 40% of the students in the sample subtracted.

Mathematical Practice:

Look for and express regularity in repeated reasoning.

- Look for repeated calculations in both general methods and for short cuts

6th Freezing In Fargo

- Which week (Sunday through Saturday) recorded the average lowest temperature?
A student noticing that all the averages are divide by 7 days should realize that comparing totals will yield some comparative results without needing to divide.

Tools For Practices and Standards

- Use MARS Tasks
- Define the meaning of the standards and practices
- Raise expectations for teachers about what students are capable of accomplishing
- Help teachers anticipate misconceptions so that they can be surfaced and addressed in class discussion and re-engagement lessons

- How do we create classroom culture?
- How do we facilitate “staff” doing mathematics together to understand purpose of the lesson, understand the mathematics before giving it to students, work as a learning community to discuss techniques, purpose of using student work, types of comments to put on student papers, how to have a plenary discussion? What are the important mathematical ideas to be drawn from students? What teacher moves help hold all students accountable for their own learning?
- Making time for lessons?
