Aylin was very excited that day. Their teachers had asked them to prepare crayons and math materials. They were going to have a surprise event. Aylin was very curious about the event. At that moment, the bell rang and the teacher entered the classroom with waste materials and crayons in his hands.

Aylin did not understand the symmetry topic they had studied last week. The teacher wrote the

letters on the board and asked the children to draw the letters in three dimensions and show the

lines of symmetry. Aylin was very upset. Because she could not understand what this topic was.

Then her friend next to her, Cem, said to Aylin, "You draw the letters, let's color them together,

and I will draw the lines of symmetry." Aylin started drawing the letters with excitement.
