The word "Tessera" in Latin means a small stone cube. They were used to make mosaics in Roman Buildings Now, it is used to refer to pictures or tiles, mostly in form of animals or life forms, which covers the surface in a symmetrical way without overlapping or leaving gaps.

Tessellations must be based on a shape. Parallelograms can be tessellated. Students have to realize that every part needed to make up the full picture is contained in the shape chosen. All you need is to repeat them.

There are 4 kind of methods, line, slice, gaps and multi method. See works from different methods and explain that they are going to work with slice method

 Escher can be regarded as a father of modern Tessellations. He is famous for his impossible depiction.

To record the observations. Stick the step by step pieces from the methods.

Activity 1:
To recognize the methods to use, I'll bring the strips of the 2 step by step tessellations to order and glue in the sketchbook.

Activity 2:
Tell them that tessellations are shapes which fit together exactly to form repeating pattern. They are going to do birds

1 - Cut a corner off at a square of thin cardboard of about 4cm.Then, tape the triangle along the top edge of the square.
2 - Cut the bottom corner off the square and tape it along the top, so that the two triangles meet in the middle.
3 - To make the beak, cut a long V-shape into the left-hand side. Tape the shape onto the triangle at the top.
4 - Draw around the bird shape. Then move the shape so that the beak fits under the wing. Draw around it again.
5 - Carry on drawing around the shape so that you build up a pattern of birds which fit into each other on all ides.
6 - Finally, paint the birds and outline with the black felt-tip pen.

Activity 3:
This will be a free choice activity of tessellations. Students can try their own shape and pattern, not just animals but anything. They can use a different method of tessellation. They can make the shapes in coloured cardboard and glue them making a hole tessellation composition or adding details and make a collage.

 

---

• Use the line method, using a triangle or a comet shape.
• Instead of colour, they can try to cut the pieces in coloured cardboard and stick them on a paper making a composition of shape and colour.
• Enter the webs from resources and follow the step by step with "Paintbrush" or "Paint" or play to shape tessellating jigsaw puzzles.

- To assess understanding, give the students de writing steps and pictures order steps from activity 2 to mach them. You only need to rub the numbers. They can be glued in the sketchbook.
- Review the children work as it progresses.
- What they want to show in their work?
- Identify what may change in their work  for future task?
