Let's explore and learn 3D shapes, which is useful for learning as well as teaching about three dimensional shapes in mathematics. It is recommended to not only students, but also teachers. This app was reviewed to get awarded 4 stars of the EAS Certification! Please visit our web page. --Abstract Features-- Ã¢â¬Â¢ This app enables you to virtually touch, measure distances / angles, or even cut shapes. Ã¢â¬Â¢ You can cut shapes along a plane which includes three point you specify. Ã¢â¬Â¢ You can expand shapes by face by face. Ã¢â¬Â¢ You can extend s
Mathematical Playground -3D Shapes- is a free educational mobile app By Jun Nakashima.It helps students in grades 3,4,5 practice the following standards 3.G.A.1,4.G.A.1,5.G.B.3.
1. 3.G.A.1 : Understand that shapes in different categories (e.g., rhombuses, rectangles, and others) may share attributes (e.g., having four sides), and that the shared attributes can define a larger category (e.g., quadrilaterals). Recognize rhombuses, rectangles, and squares as examples of quadrilaterals, and draw examples of quadrilaterals that do not belong to any of these subcategories..
2. 4.G.A.1 : Draw points, lines, line segments, rays, angles (right, acute, obtuse), and perpendicular and parallel lines. Identify these in two-dimensional figures..
3. 5.G.B.3 : Understand that attributes belonging to a category of two-dimensional figures also belong to all subcategories of that category. For example, all rectangles have four right angles and squares are rectangles, so all squares have four right angles..
