Explore how to make geometry lessons accessible to all students by differentiating instruction for diverse learners, including those with special needs. Understand the importance of removing barriers and providing modifications, assessment strategies, and addressing specific learning disabilities and ADHD. Discover methods to enhance spatial reasoning through geometric systems and practices.

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
