© 2005 UT System/TEA 2 The Characteristics of Students with Mathematics Disabilities (MD) Procedural difficulties Immature strategies use Errors in math problem execution Memory problems Poor long-term memory retrieval skills Working memory deficits Visual/spatial deficits Weak visual/spatial representations Low number sense Number magnitude comparison confusion Poor number naming and writing

© 2005 UT System/TEA 3 Core Educational Problem: Assessment Limited availability of technically adequate measures for identification and to monitor response to intervention of Tier 2 students in the primary grades Need to develop technically adequate measures for early mathematics number, operation, and quantitative reasoning skills and concepts Measures can contribute to an understanding of predictors of early mathematics performance, inform mathematics instructional decisions, and change mathematics outcomes for students who are at risk for mathematics difficulties (Chard, Clarke, Baker, Otterstedt, Braun, & Katz, 2005)

© 2005 UT System/TEA 4 What is the 3-Tier Mathematics Intervention Model? Is an assessment & intervention model designed to meet the instructional needs of students in grades K - 2 who are identified as struggling with mathematics • Provides a framework for providing instruction and using assessment data to inform decision-making Is a response-to-intervention model (developing) Focuses on standards-based intervention (number & operation)

© 2005 UT System/TEA 5 What are the Components of the 3- Tier Mathematics Intervention Model? Tier 1: Core classroom instruction for all students (45-60 minutes-observed in K-4) Tier 2: Intervention for approximately 10 - 30% of identified students (15-20 minutes-10 - 12 weeks - 3 to 4 days a week) Tier 3: Intensive intervention for approximately 5-8% of identified students (may include special education students; probably another 20 minutes?)

© 2005 UT System/TEA 6 What are the Components of the 3- Tier Mathematics Intervention Model? Tier 1 Seems to be based on National Science Foundation instructional recommendations, teacher created lessons, basal based instruction, NCTM Standards (based on observations) Focus on instructional adaptations (content, delivery, materials, activity): Tier 1 + adaptations- keep your eye on Tier 2
