Could use a spreadsheet already set to the correct row height and column width; could be supported to access the spreadsheet file on a device; could use the Knowledge organiser to support them with understanding and using keywords, such as pixels.
Pupils working at greater depth
Could create more detailed images by adjusting the pixel size in their spreadsheet (smaller column width, row height or zooming out); should be encouraged to think about shading images using a range of colours; could be encouraged to use the ‘custom’ tab to explore colour options.
