Using the Logifaces blocks, they need to imitate the surface form using paper. They observe their paper designs from above to be able to form their surfaces. Origami tessellations have very strict rules about how they are formed. This is why we turn the exercise the other way around. [br][br]LESSON 2 [br]They use the blocks and create copies of the blocks or geometrical shapes. They arrange these pieces imitating the surface structure.[br][/td][/tr]
