hp digital whiteboard. ????In the mathematics classroom, due to time and space restrictions, it is difficult to show the true face of the object, making it difficult for students to experience the sense of space. For example, when explaining the characteristics of the cuboid, the traditional teaching is to use the cuboid teaching aids for students to observe. Because the angle of observation of students and the teacher's presentation will block and other reasons, so that students can not see certain features of the cuboid, using the electronic whiteboard teaching technology can solve this problem well. According to the teaching requirements, I need to guide students to explore the three aspects of the face, the edge and the apex of the cuboid. First, on the screen, the surface, ribs and vertices are displayed by the computer, so that the students can observe that the rectangular parallelepiped has 6 faces, 12 edges and 8 vertices. Then, by observing the operation of the three sets of ribs in the rectangular frame, the students can observe the relative edges. The length is equal; finally, when it comes to explaining the relationship between the size of the six faces of the rectangular parallelepiped, the computer demonstrates the overlapping of the top, bottom, left and right, front and back. In this way, the students conclude that the relative faces are equal in area. Because the picture can be combined with static and dynamic, it stimulates the senses of the students, makes the observation focus more prominent, and is more conducive to cultivating students' correct observation methods, triggering students' thinking, improving the concentration of learning, and melting the difficulties of knowledge.

The IQAio GR519 is an upgraded lightweight version based on the original IQAio GR511. The original dual-cavity structure was changed to a bottom-edge structure, so that the minimalist design accommodates modern classrooms and conference rooms. With one IQProjector V2 and one IQView E3821, you can achieve flexible and intelligent classroom.
