# Potato Printing Tessellation

Recognising and creating patterns is one of the key areas for math as a child develops what may start as putting together a row of coloured beads is the foundation that lead to the discovery of the Fibonacci Sequence and the golden ratio – yes that’s a big step from making simple patterns in preschool and kindergarten but everyone has to start somewhere. Tessellation is just one area of pattern making that it is especially easy to explore through art and is a fun way to get kids to start thinking in terms of the number of sides, angles as well as how shapes fit together. Trying through trial and error to get shapes to fit together without gaps children will start to develop an understanding of how a triangle is connected to a rectangle/square and from there how triangles can be connected to other shapes. For this week’s #TeachECE theme, we’re looking a fruit and vegetables so using potatoes to print out some simple tessellation is a fun art and maths activity.

## Learning Objectives

• To print
• To start to grasp tessellation and pattern making with simple triangles and rectangles

## Materials Needed

Potato

Knife

Cutting Board

Paper

Two different coloured paints

## Preparation

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.

Cut 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. Repeat on the other half of the potato.

This time, we will be using squares and triangles as squares and triangles tessellate nicely. Cut out a square from one of the potato halves.

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.

## Creating Potato Print Tessellation

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. 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.

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.

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.

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.

She repeated with a row of the squares and another row of the triangles.

Whilst we created the patterns we talked about the number of sides of the shapes, how many corners the shapes had.

1. This is so cool! It is a great starting point and could evolve as time goes along!. Thanks.

2. This is a fantastic early math activity and looks like so much fun!

3. Danielle says:

So pretty and such a clever idea! My kids would adore this.

4. I love this idea especially with potatoes that I forgot were in the closet and have become a bit soft.

5. oh wow! this is gorgeous! great idea i must try it soon.
