In a fraction wall each row or layer of the wall represents one whole number. The layers are divided into a number of bricks and hence each brick represents a fraction whose denominator is equal to the number of bricks in that layer. Each brick can be turned on or off by clicking it. This wall also allows the display of decimal and percentage values. To the right of the wall are boxes which can be hidden, the value of each box is fraction of the wall that has been turned on. Selecting different walls When you launch this interactive teaching program the initial wall is a mixed one showing 3 distinct fraction families. Fractions, decimals or percentages Use the display type control to display decimals (rounded to 2dp), percentages (rounded to 1dp), fractions or none.

The equivalent fraction control Normally when you click a brick to turn it on or off, only that brick is affected. Other controls. Desmos Classroom Activities. Visual Patterns - 1-20.

Some people say that mathematics is the science of patterns.

That's not a bad description. Not only do patterns take many forms over the range of school mathematics, they are also a unifying theme. Number patterns—such as 3, 6, 9, 12—are familiar to us since they are among the patterns we first learn as young students. As we advance, we experience number patterns again through the huge concept of functions in mathematics. But patterns are much broader.

But what maths did they learn and how did they learn it? In this resource pack, Dr Eleanor Robson, shows us how we can find out about an ancient civilisation through the objects they left behind. She demonstrates clay tablets on which Babylonian children worked at their multiplication tables - in base 60! Through the video clips and follow-up resources, we can find out how they did arithmetic and how they learnt their tables.

Eleanor also demonstrates the difference between how we generally draw a triangle now and then, and how the Babylonian style of writing - cuneiform - relates to their triangles. The resources in this pack complement the video clips, providing activities designed to help students understand the similarities and differences between maths then and now.
