1. Mastering the Facts (K-5)
Moving from counting to strategies to recall.
Summer 2011 Flex Day
Math Workshop

2. The Problem
4th and 5th graders are not fluent with addition and subtraction.
Middle schoolers are not fluent with multiplication.
Mastery relies on how well students have constructed relationships about numbers and how well they understand the operations. It is dependent on development of reasoning strategies.

3. Computational Fluency…
Means that students have strategies to solve a problem. Those strategies include mental strategies, a combination of intermediate written steps and mental calculation, and complete written solutions.
Students should be flexible in their choice of algorithm or procedure, and they can use one method to check another.

4. The Standard- NCTM NCTM Focal Points:
Knowing basic number combinations- single digit addition and multiplication pairs and their counterparts for subtraction and division- is essential.
NCTM Focal Points:
1st grade: Addition & Subtraction concepts learned
2nd grade: Addition & Subtraction mastery/quick recall
3rd grade: Multiplication & Division concepts learned
4th grade: Multiplication & Division concepts mastery and quick recall

5. The Need
We need much more than flashcards and timed tests to teach our students. Quick and accurate recall with basic facts is a developmental process.
The Approach
Memorize facts in isolation
Teach Strategies
Guide student generated strategies
Are there limitations with these?

6. Limitations to Memorizing:
Inefficient- there are so many- overwhelming!
Inappropriate applications- misapply facts and don’t check work
Inflexibility- strategies aren’t flexible to other sums.
Ineffective for struggling learners, causing anxiety, decreasing interest, and confidence

7. Limitations to teaching strategies:
Focus on memorizing a strategy and which facts work with that strategy doesn’t always work. Students memorize strategies that don’t make sense to them and they are likely to misapply them.
When students don’t memorize well, they resort to counting.

8. What about Guiding Strategies?
Tasks and problems must be designed to promote invention of effective strategies.
Strategies must be clearly articulated.
Strategies must be shared and highlighted.
Create lots of opportunities to highlight and share them.

9. So what do we do?
Plan experiences to help movement from counting to strategies to recall.
Teach reasoning strategies.
Use story problems to provide context.
Use many exposures. One is not enough to learn a strategy.

10. Investigations
Fluency with the Facts

11. Grade Level Fluency
Grade 1- addition combinations that make 10 (practiced & assessed)
Grade 2 – addition combinations to (practiced & assessed)
Grade 3 – subtraction facts (practiced & assessed)
Multiplication facts (to product of 50
Grade 4 – Multiplication facts (to 12 x 12)
Grade 5 – Division facts practiced &assessed.

12. Facts Practice in Investigations:
Routines and 10-Minute Math
Games and Activities
HW/Practice Pages
Sorting Cards

13. Fluency Assessment in Investigations:
K-2: Individual and small groups
3-5: Ongoing assessments
30 problems in 3 min. to determine facts to “work on”
2nd Grade: Unit 8 (session 4.5) 26 addition problems with student checklist to assess fluency per student
3rd Grade: Unit 1 (session 2.5) 33 addition problems in 5 min. Unit 8 (session 1.4) 30 multiplication problems in 3 min. to determine facts “to work on”.
4th Grade: Unit 1 (session 2.5) 30 multiplication problems in 5 min. Unit 3 (session 3.4) 30 multiplication problems in 5 min.
5th Grade: Unit 3 (session 3.1) 30 division facts in 5 min.

17. Focus Points & Benchmarks: What’s the difference?
Focus Points- what you teach
Benchmarks- what you assess
