The dimensions of the A series paper sizes, as defined by ISO 216, are given in the table below in both millimetres and inches (cm measurements can be obtained by dividing mm value by 10). The A Series paper size chart to the right gives a visual explanation of how the sizes relate to each other - for example A5 is half of A4 size paper and A2 is half of A1 size paper. www.papersizes.org
In this lesson, students “paint” with torn paper using a limited number of values found in a grayscale image. Using torn paper instead of direct painting requires them to visually divide the gray areas into separate shapes and define each shape individually.
These personal reference rings are such an awesome tool to help young learners as they work independently. One teacher writes, "This product is sure to inspire our children to take more responsibility for their own education and at the same time provide the scaffolding they need to meet academic challenges." $
