Grades:  3-5
Vocabulary:  Computer, Tessellations, Escher, Pattern, Repeat,
Edit, Copy, Paste, Design, Interlocking, Square
Objectives: After being shown how to create a tessellation, the student will create their own.  The picture must be interlocking. 
Method:  Create a square by using the square tool.  By using the pencil, draw a simple design on the top of the square.  Use the dotted save square (scissors) and enclose the new design.  Copy it and paste.  Move the pasted one to the bottom of the inside of the square.  Draw a simple design to the left of the square.  Do not let it go above or below the original square.  Use the dotted square (scissors) and save this new design.  Copy and paste.  Move this new one to the right of the inside of the original square.  Go back and erase the lines of the square that you don’t need to use.  They can clean up the drawing in Zoom or use the magnifying glass.  “Save as”  Decorate the inside of the design.  “Save as“.  Use the dotted square (scissors) and copy. Go to a New screen and paste.  Paste it again.  Move it to interlock with the original design.  Continue doing the same until they have the pattern that they want.  Leave the edges plain, do not make it into wallpaper. They should type their name or write their name and room # on the bottom edge.  Save it to their disk.
Materials:  Paint program, Computer, paper, disk.
Time allowed:  Computer lab or 15 minute time sections done with timer in the art room.  Rotate students on the computers.  Finished project may take several weeks. Once a student has had 3- 15 minute time periods, he should be able to print a project.
Assessment-Evaluation: Did the student use the materials, techniques and processes correctly?  Did the student consider the elements and principles of design?
Composition? Design or drawing on the inside, interlocking tessellation, Does it work?
Other resources:  Samples on the board, Books on M.C Escher.
Artist M. C. Escher’s work became well known for his precise, mathematical method he used in order to construct tessellations.  The word tessellation came to use from the Latin tessella, which was the small, square stone or tile used in ancient Roman mosaics.  Tiles and mosaics are common synonyms for tessellations.
