Today we'll watch a video and we'll try to solve a mistery called 'the missing square'. After the mistery is solved, try to construct the 13 convex figures with the Tangram. Do you know what a

**convex figure**is? If you choose any two points inside the figure, the whole line between the points must also be inside the figure.### Activities

After the mistery is solved, try to construct the 13 convex figures with the Tangram. Do you know what a convex figure is? If you choose any two points inside the figure, the whole line between the points must also be inside the figure. Try to build each one of the following figures.

- Take a white paper. Write down the solution to the missing square mistery. You can use a small drawing if you prefer.
- Now, take your tangram pieces and try to build at least 2 of the convex figures below. Draw the solution on the paper. Remember that you must use all 7 tans in order to construct the shapes.
