“Can you touch, cut, and rotate three-dimensional figures with your hands?!
Free AR app content reflecting the 2015 revised curriculum produced by EBSMath.
Components of three-dimensional figures, three-dimensional figures and development views, rotating bodies, stacking trees
By decomposing, combining, and rotating three-dimensional figures through the
Develop mathematical thinking skills. Now let's play and do math!

Touch the three-dimensional figure directly using AR technology.
You can choose a gift, glue the wrapping paper directly to the face, glue the corners with color glue, and choose the embellishments to attach to the vertices.
You can also fold the development view or cut the three-dimensional figure directly to check the cross section.
You can also observe the stacking trees decorated with pretty stickers by stacking them layer by layer and turning them around.
And, you can take a picture of four shapes and leave pleasant memories with three-dimensional shapes!

What can you learn from ?

1. [Components of three-dimensional figures]
- Know and find the faces, edges, and vertices of three-dimensional figures.
- You can directly count the number of faces, corners, and vertices of a three-dimensional figure while manipulating the figure.

2. [Three-dimensional figure and development view]
- You can understand the development by unfolding the cube-shaped box, and you can find the development of various cubes.
- Know how to draw the development of a cuboid, and you can find the development of a cuboid in various ways.

3. [Rotating body]
- You can make a rotating body by connecting three and four points with a straight line as an axis, and observe the three-dimensional shape created when you rotate it.
- You can observe the cut section of the rotating body (cylinder, cone, sphere) and discover the properties of the rotating body through the cut section.

4. [Stacking Tree]
- You can express the shape of stacking wood by writing numbers on the shape viewed from above.
- You can express the shape of stacking wood in a layer-by-layer shape.
- You can make various shapes with stacking wood.
