Hands-On Math Line Design is an interactive learning environment where students explore and discover the fundamental ideas of geometry. It is a perfect classroom tool for mathematics enrichment. While using this app students will use mathematical thinking skills to create colorful designs. Students will be amazed that curved designs can be created with only straight line segments. Encourage your students to take some time to explore LineDesign, and as they do help them to discuss their findings. Elicit math vocabulary while creating designs. Younger learners will benefit from using the terms such as line, line segment, end point, intersection, rectangle, square, circle, and triangle. For older students teachers may want to use some of the options available by tapping the grid icon. Based on the shape selected either a rectangular or polar coordinate graphic system is displayed. Teachers will want to use these features as components of their coordinate geometry and angle measurement curriculum. Topics: Properties of Geometric Shapes Geometric Terminology Classification of Angles Properties of Polygons Coordinate Systems (Rectangular and Polar) Angles and Degrees Parts of a Circle Mathematical Thinking and Reasoning Relationship between Geometry and Art
