![]() ![]() You don't need to draw the pattern pdf is provided just watch the video and you can use it for any other project. Do not throw away any cutouts these will be useful for our next projects.įor this project, we have drawn a 12 fold rosette found in various places. ![]() Stick the pattern on cardboard and enclose it in a plexiglass case.(optional).You can use glue to hold all the cut patterns in one place. Align all the cut patterns serially and you are done.Repeat the same steps for the other 9 square templates and card stock.Remove the masking tape from the cut cardstock as well and store the pattern in a hardbound book. Remove the template when all of the patterns are cut by carefully removing the masking tape.Apply enough pressure to cut through both template and card stock. Use a ruler and a sharp hobby knife to cut the template.Now place the square template on the colored card stock aligning all four corners.The masking tape used needs to be of light adhesive we do not want to tear our patterned paper when we remove it from the table. Place the square colored card stock of the same size on a table or a cutting mat and use masking tape on the corners of the square cardstock to hold it in one place.Start by cutting the template into a square.In this project we are going to use a 12 fold rosette found in Al Nasir mosque, Cairo, Egypt I want you to find the difference in constructing the pattern. Here is both way a 8 fold pattern can be drawn. While the star revealed in the exact method has equal corners. You can observe in the images that the star pattern revealed after tessellating the 8 fold geometric pattern in the approximate method has unequal corners. The reason why Islamic geometric patterns use the exact method is because the revealing pattern after tessellating is symmetric which upholds the symmetry of the whole tessellated pattern. This makes the petal of the approximate method look squished. In the exact method, four sides of the six-sided petal are the same while in the approximate method 2 sides of the six-sided petal are the same. For an untrained eye, both of the geometric patterns may look the same but a small difference gives rise to large errors when tessellated.Īn easy way to understand if the pattern is drawn with the exact method or approximate method is to look for the petals. Whilst we created the patterns we talked about the number of sides of the shapes, how many corners the shapes had.The thing which differs Islamic geometric patterns from other geometric patterns is they use the Exact method to construct the patterns. She repeated with a row of the squares and another row of the triangles. So she proceeded to produce a row of squares and then the following row of triangles printing a row one direction and then rotating the potato to print in between the triangles to create a full row. We then looked at whether that was the easiest way to get the pattern and T pointed out that two triangles together would fit along 1 side of the square and the squares all made a neat row. The first attempt was very random but it was interesting to see how T was trying to get the squares and triangles to fit together. After demonstrating by printing 4 triangles around a square, I set the challenge to fill the paper with a pattern with no spaces using just the triangles and squares. We started off with a little demonstration of how the sides of a triangle were, all the same, size as the 4 sides of the square and that we could print them to get them to match up easily. Use this square to cut out an equilateral triangle from the other potato half – it took me a little measuring and comparing to get the measurements of the sides of both the square and triangle equal however if you have a square template and a triangle template that you know tessellate then use this to create the shapes in the bottom of the potato half. Cut out a square from one of the potato halves. This time, we will be using squares and triangles as squares and triangles tessellate nicely. This is nice to do the cutting of the potato with the children, however, to get accurate shapes that will fit together it’s much easier to do it independently in preparation for the activity especially if you are doing this with a class or a group of children.Ĭut a potato in half – your children will find it easier to print if you create a handle in the top of the potato – use a knife to cut a section out from one side – leave a centre section of about 1cm and then cut out a similar section from the other side.
