  2. In this changing world, those who understand and can do mathematics will have significantly enhanced opportunities and options for shaping their futures. NCTM, 2000

  3. Guiding Questions • What factors impair performance? • How do standards impact students? • What math skills are essential? • What teaching strategies can be applied? • What methods are effective for teaching basic math facts? • What methods are effective for problem solving?

  4. Knowing and Doing Math • Knowing • Comprehend basic principles • More than one way to explain • More than one acceptable answer • “Difference between 2 numbers” • Doing • Apply strategies to complete item • “take away”

  5. Factors • 60% of students with LD • Reading, writing, attending, memory, language, motivation • (Montague, Bos, & Doucette, 1991) • Procedural & representational • (Geary, 1993) • Failure to understand concepts, lack pre-requisite skills, maintain facts • (Cox, 1975; Miller & Milam, 1987; et. al) • Need direction instruction, strategic

  6. Problem solving Communication ideas Reasoning Everyday applications Reasonableness Estimation Computational skills Algebraic thinking Measurement Geometry Statistics Probablity NCTM

  7. Effective Instruction • Appropriate math content • Problem solving, communicating ideas, everyday applications, computation • Establish goals & expectations • Assessment • Systematic & explicit instruction • Demonstrate-prompt -practice sequence • Highly organized, step by step presentation what, when and why use target skill • Insure understanding and task demands • Use learning principles • Attention, reinforcement, varied practice motivation

  8. Efficient Teaching • Demonstrate • Guided practice with prompts/feedback • Independent practice with feedback • Advanced organizers • Mastery of skill as generalization level

  9. Teach to understand concepts • Concrete-representational-abstract sequence • Learning concepts and rules • e.g. communative property of addition, inverse relationship, place value, # time 0 = 0 • Monitor progress • Check for understanding, interact, demonstrate • Provide feedback • Essential promote learning, mastery, independent learning, plan activities, motivation, confidence abilities • Immediate, basic & elaborate

  10. Teach to mastery • Automaticity • Benefits – retention, higher level skills, completion, positive feelings • Independent practice • Games, peers, computers, self monitor • Teach problem solving skills • Math knowledge, application, engage thinking • Strategy instruction parallel

  11. Teach generalization • Perform different situations • Motivation to apply, discuss why and how used, varied examples, mastery to use rather than remember • Positive attitude • Goal setting, success on prior skills, progress chart, high expectations, enthusiasm, reinforcing

  12. Math Curricula • Distar Arithmetic – SRA • Connecting Math Concepts • Edmark • Project MATH • Real Life Math • Strategic Math • Touch Math • Rapid, sequenced, scripted, direct instruction • 1 2 3 4 5 6 7 8 9

  13. Strategic Math • Pretest lesson • Teach concrete application • Teach representational application • DRAW (Discover, Read problem, Answer with drawing, Write answer) • Teach abstract application • Posttest • Provide practice to fluency • Strategic Math Series, Mercer & Miller, 1991

  14. Math Methods for SWD • Curriculum-based Assessment & Error Analysis • Spiral curriculum • Fast paced, insufficient practice, developmental sequence gaps, order of concepts, number of concepts • Performance: frustration < 70 to success 90% • Construct probes for error patterns • “Slice back” to re-teach lower skill

  15. Concrete to Seimconcrete • Manipulatives rather than pictures or numerals and symbols • Repeated opportunities • Relate manipulatives to numbers immediately • Build understanding of concepts • Questions and verbalize thinking • Check answers with manipulatives

  16. Direct Instruction • Focused, explicit, interactive • Tasks analyzed, clear examples (models), questions & feedback • Hi success • Models, demonstration, time delay • Systematic practice in real world contexts • Provide calculators as postsecondary level

  17. Sequence & Rule Based • Resequence texts • e.g. teach “zero” facts earlier • Sameness to reduce memorization • E.g. 0 times any number = 0

  18. Build Strategies • Self instruction & mnemonics • Good with direct instruction • Associate pictures, visual imagery • Should not substitute for practice for mastery • Good for rote memory deficits

  19. Motivation for Practice • Games • Bingo, blackjack, jeopardy, math basketball • Real Life • Newspapers, internet, technical courses, solve real life problems • Self-Monitoring, Goal Setting • Record, graph, choice of goals, conference, self-talk

  20. Cooperative Learning • Interactive practice, group rewards • Computer Instruction • Tutorial, drill & practice, software • With teacher directed instruction

  21. Teacher Student Dialogues • Math reasoning & problem solving • Explicit modeling centered on concepts • Verbal rehearsal, feedback, guided practice, check for understanding • Think alouds, scaffolded practice

  22. Instructional Tips • Number Sense – numbers to objects • One to one correspondence • Readiness skill • Numeration • Number values • Seriation • Ordinal, less/more • Place value • Ones, tens, hundreds

  23. Basic Facts & Operations • Addition • Sticks, counters, dots on cards, Touch Math, sums of ten, number lines, 1-5 w/9-5 below • Subtraction • Counters, sticks, number line, tally marks, Touch Math, • Multiplication • Groups in rows, Geoboards-cubes, teach rules, fingers • Division • Counters, number line to 25

  24. Complex Operations • Understand place value, regrouping, state the operation, graph paper • Addition with regrouping • Concrete manipulatives, mnemonic or visual reminders

  25. Other Essential Skills • Fractions • Need systematic practice, examples • Explicitly define whole, fractions equal parts • Fair sharing • Formal symbols, ½ or ¼ • Concrete aids before teaching rules • Mastering Fractions – interactive videodisc • Need more time

  26. Decimals • Concrete manipulatives • Represent fractions with denominators 10 or 100 • Visual representation less that whole • Algebra • Direct instruction, think alouds, concrete to abstract, strategy (FOIL)

  27. Arithmetic Word Problems • Group problems around familiar themes • Pictures & manipulatives of the problem • Attack word problems • Emphasize understanding with visuals, question for important information, model strategies for solving, give feedback during process - SOLVE

  28. Enhance Instruction • Increase instructional time, reduced independent practice • Review, directed instruction, guided practice, independent practice with feedback • Use concrete objectives • Teach key math terms, “sum” • Small group instruction • Real life examples • Varied reinforcement styles, process rather product • Lock, R.H. (1996). Adapting Mathematics Instruction in General Education for Students with Mathematics Disabilities, CLD.
