How to help struggling students master math facts

  1. 1. How to Help Struggling Student’s Obtain Math Fact Fluency
  2. 2. Three Phases of Fact Fluency:• Phase 1: Counting Strategies – using object counting or verbal counting to determine an answer• Phase 2: Reasoning Strategies – using known information to logically determine the answer of an unknown combination• Phase 3: Mastery – efficient (fast and accurate) production of answers
  3. 3. Two Approaches to Fact Fluency:• Conventional Wisdom: Mastery grows out of memorizing individual facts by rote through repeated practice and reinforcement.• Number-Sense View: Mastery that underlies computational fluency grows out of discovering the numerous patterns and relationships that interconnect the basic combinations.
  4. 4. Conventional Wisdom:• Believe that phase 1 (counting strategies) and phase 2 (reasoning strategies) are not necessary for achieving the storehouse of facts that is the basis of combination mastery.
  5. 5. Number Sense View:• Phase 1 and phase 2 play an integral and necessary role in achieving phase 3 mastery of basic number combinations is viewed as an outgrowth or consequence of number sense, which is defined as well-interconnected knowledge about numbers and how they operate or interact.
  6. 6. What does this mean for struggling learners?• According to conventional wisdom, learning difficulties are due largely to defects in the learner.• According to the number-sense view, they are due largely to inadequate or inappropriate instruction.
  7. 7. Struggling Learners and Conventional Wisdom:• Belief that learning difficulties are attributed largely or solely related to their cognitive limitations. – Heavy reliance on counting strategies – Have capacity to learn reasoning strategies but an apparent inability to spontaneously invent such strategies – Inability to learn or retain basic number combinations, particularly those involving numbers greater than 5 – A high error rate in recalling facts *Struggling learners appear to get stuck in phase 1 (counting) of number-combination development. These learners can sometimes achieve phase 2 (reasoning), at least temporarily, if they are taught reasoning strategies directly. In this approach many struggling learners never achieve phase 3 (mastery).
  8. 8. Struggling Learners and Number-Sense:• Believe for two reasons struggling students have difficulty mastering the basic combinations: – They lack adequate informal knowledge, which is a critical basis for understanding and successfully learning formal mathematical and devising effective problem-solving reasoning strategies. – The conventional approach makes learning the basic number combinations unduly difficult and anxiety provoking. The focus on memorizing individual combinations robs children of mathematical proficiency. • Far more challenging than meaningful and many give up on learning the basic combinations. (inefficiency) • When children focus on memorizing facts by rote instead of making sense of school mathematics or connecting it with their knowledge, they are more prone to misapply this knowledge because they make no effort to check themselves or they miss opportunities for applying what they do know (inappropriate applications) • When instruction does not help or encourage children to construct concepts or look for patterns or relationships, they are less likely to spontaneously invent reasoning strategies, and thus they continue to rely on counting strategies. (inflexibility)
  9. 9. So . .How do we Help Struggling Learners: • Conventional Wisdom: – Recommend focusing on short-term, direct approach • Number-Sense: – Recommend a long-term, indirect approach
  10. 10. Conventional Wisdom Suggestion:• Extensive drill and practice – Can be known as “over-learning”
  11. 11. Number-Sense Suggestion:• Efforts to promote computational fluency be intertwined with efforts to foster conceptual understanding, strategic mathematical thinking and a productive disposition. – This includes four instructional implications :
  12. 12. Four Implications:1. Patiently help children construct number sense by encouraging them to invent, share, and refine informal strategies. • Help children gradually build up big ideas, such as composition and decomposition2. Promote meaningful memorization or mastery of basic combinations by encouraging children to focus on looking for patterns and relationships. • Concentrate on Fact Families • Encourage children to build on what they already know (build on if they already know doubles) • Use different reasoning strategies which may require different approaches (may require more structured discovery learning activities)
  13. 13. Four Implications Continued:3. Practice is important, but use it wisely.– Use practice as an opportunity to discover patterns and relationships– Focus on making reasoning strategies more automatic, not on drilling isolated facts.– The learning and practice of number combinations should be done purposefully.– Practice to ensure that efficiency not be done prematurely – that is before children have constructed a conceptual understanding of written math and had the chance to go through the counting and reasoning phases.4. Students should be encouraged to use a variety of strategies including automatic or semi-automatic rules and reasoning processes.
  14. 14. In Conclusion:• Using the guidelines for meaningful inquiry-based, and purposeful approach can also help students achieve the other aspects of mathematical proficiency: conceptual understanding, strategic mathematical thinking, and a productive disposition toward learning and using mathematics.• Such an approach can help all children and may be particularly helpful approach for children who have been labeled as struggling learners, but who do not exhibit hard signs of cognitive difficulties.
  15. 15. 10 Minute Math Protocol Ideas:• After initial lessons in math fact strategies are introduced, teachers need to guide students through phase 2 (reasoning strategies) and phase 3 (mastery) working toward quick recall in quick 10 minute activities where specific strategies are developed for students. – The activities are teacher-led, student-centered, and essential for developing basic fact fluency and focus on: • Build Number Sense • Build Vocabulary • Build Conceptual Knowledge • Build Mathematical Modeling Skills • Build Procedural Fluency • Build Strategic Competence • Build Strong Mathematical Disposition
  16. 16. Some Common Strategies to Use: • Doubles • Doubles Plus 1 • Half Facts • Number Line It • Ten More • Ten Less • Multiples • Counting Up
  17. 17. How/When to Use:• Whenever a small chunk of time exists: – Morning Opening – Part of Bell Ringer/Do Now – During Calendar – Before Lunch – Before/After Recess – During Bathroom Break/Snack – End of the Day
