NCIDA 2009Helping Students Stay Connected in Math Joanie Gerken, M.Ed. Fellow, A.O.G.P.E.
Dyscalculia • Dyscalculia = “difficulty in learning or comprehending mathematics” dyscalculia.org • Identified in patients suffering brain trauma resulting in math problems • Arithmetic difficulties in calculation and number memory deficits “dys” = Greek, “badly” “calculia” = Latin, “calculare”, “to count”
Dyslexia/ Dyscalculia • Are they related? DYSLEXIA DYSCALCULIA
Characteristics of Dyscalculia • Confusing signs, +, -, x, ÷ • Inability to tell which is larger • Rely on ‘counting on’ strategies • Difficulty with mental math, tables • Inability to remember concepts, rules, sequences, formulas • Rotate numbers, 56 as 65 • Difficulty estimating everyday time, money, comparisons in amount and measurement • Difficulty with score keeping, rhythm-sequential processing; dance, cheerleading
Simulation How does it feel to many children in math class! Errors often occur when students don’t know basic facts fluently Project Access, web.utk.edu/~access/mathdisabilities.html
Addition Sometimes charts are used to assist poor recall
Multiplication Used to help with multiplying and dividing

Factors Influencing All Learning • Language disorders • Reading difficulty • Accuracy • Rate • Repetition • Learning Style Attention difficulties Processing deficits Memory deficits Motor skills difficulty
Critical Factors Affecting Math Learning style Math language Cognitive level Prerequisite skills Levels of Learning mastery
7 Prerequisite Skills • Inductive reasoning/ easily seeing patterns in generalizations 6. Deductive reasoning/ draw conclusions 5. Estimation skills 4. Visualization/ picture what’s going on in your head 3. Recognize patterns and continue it 2. Sense of directionality, spatial orientation and organization 1. Follow a sequence

What made this task difficult? Pattern Recognition Not knowing basic facts/ with all information new skills Fluency
Best Practices in Math • Choose fewer topics to teach at each grade level • Be diagnostic and prescriptive/individualize to match needs • Guide to success is pacing and vice versa • Be mindful of learning style/ moving from simple to complex • Give feedback and clues to help scaffold learning • Teach concepts and promote fact fluency • Focus on applying problem solving skills
1/3 of US students are at or above grade level in math National Center for Educational Statistics, 2005

NCTM recommends • Develop problem solving and critical thinking skills • Understand and generalize information • Fluency
Best Practices in Math • Choose fewer topics to teach at each grade level • Be diagnostic and prescriptive/individualize to match needs • Guide to success is pacing and vice versa • Be mindful of learning style/ moving from simple to complex • Give feedback and clues to help scaffold learning • Teach concepts and promote fact fluency • Focus on applying problem solving skills
Focus on what makes most tasks difficult Pattern Recognition Not knowing basic facts/ with all concept or process information new skills Fluency
Informal Inventory and error analysis Doesn’t have to be long Sampling of problems testing Number sense Sequencing Pattern recognition Computation Problem solving

Problem solving Molly collects stamps. She has 17 new stamps to put in her stamp book. If she can fit 6 stamps on each page, how many pages will she need? Show your work with pictures, words or numbers
Error Analysis • Find the pattern for common errors • Find the reason for the error • memory for facts/sign confusion • sequence of steps • understanding of process • visualization • inference • carelessness or lack of attention to detail
Find the common errors 64 32 76 81 + 27 - 25+33- 56 102 13 109 35
Samples of errors/What do the errors mean? Refer to prerequisite skills needed! 10 4 • 3 1 • - 2 8 + Get out the manipulatives! Next draw pictures
