Reaching Exceptional Learners Geometrical & Spatial Reasoning
Conversation in Mathematics • Discuss how the lesson was accessible to all the students in the class. What did the teacher do to differentiate the lesson?
Exceptionality • Pedagogy
Access and Equity • Equal access versus identical instruction • High expectations • Providing modifications for students with an IEP versus unidentified students • Importance curriculum and instruction plays • Teachers of students of special needs must be familiar with the grade level curriculum and practices of general education students
Role of Assessment • Individual assessments provide the most information • Modification of assessments for children with language difficulties (are we testing language or math?)
Specified Learning Disabilities & ADD/ADHD • For a child to be considered having a specific learning disability, there must be a significant gap between his intelligence and achievement in one ore more of the following areas: • Oral Expression • Listening comprehension • Written expression • Basic reading skills • Reading comprehension • Math calculations • Math reasoning
Possible Barriers • Memory • Self-regulation • Visual procession • Language processing • Related academic skills • Motor skills
Dyscalculia • Disorder in calculation • May perform inconsistently from one year to the next - quality of instruction is critical! • May perform at grade level in other subject areas, such as reading.
Students with Severe Learning Needs • All students need to pass through the same steps: concrete/semi-concrete/abstract. • They basically need to make the same generalizations, but they may take much longer to do so.
Geometric & Spatial Reasoning • Content
The Four Geometric Systems • Topological Geometry • Transformational Geometry • Euclidean Geometry • Coordinate Geometry
Spatial Reasoning • A combination of Topological and Transformational Geometry • symmetry • flip • slide • rotation (rotational point outside the shape; rotational point inside the shape)
Euclidean Geometry(two and three-dimensional figures) • Polygon sort • Three-dimensional solids (always use actual solids before introducing pictures - each pair of children need to be able to manipulate their own set of solids).
Coordinate Geometry • The Cartesian Plane • Ordered Pairs • Translations
