Count the dots
This is a single page activity to encourage children to appreciate the structure of the number system. There are 100 squares on the page and each one has 100 dots in it.
Hence there are 10 000 dots overall, structured as 10 x 10 x 10 x 10. The enlarged detail helps to prompt children and will also help those who have difficulty keeping track, when counting.
The page can be displayed on the computer screen or whiteboard for a whole class to see. As the file is in PDF format it is easily enlarged without any loss of detail. In this way the whole class could discuss the structure and count the dots.
If you have a large display space and lots of patience, an excellent activity is to take 100 copies of the grid, trim them and join them together. You need about 1.8m by 1.8m for this but when finished you will have a display of one million dots.
A special version of the grid is available for this. It does not have the red enlargement loop on it. To get it click here.
Much simpler arrays of dots are available from the main resources by clicking here.
