1.Butterfly Wings. On a copy of BLM 41, students draw patterns on one side of the wings. They then swap and their partner draws the EXACT same pattern on the other side to make it symmetrical.

2. Mirror shapes. Place a line of masking tape on the floor. Ask one child to make a pattern using pattern blocks on one side of the tape. Place a mirror on the tape and ask students to discuss what they see. Now have them make the mirror image on the other side of the tape.
