Here is another set of pages, just published, which concentrates on adding a single digit to a multiple of 10. It is another on our series of addition grids, which can be used as a check to see how well children have mastered this skill. It is interesting to watch to see how children tackle these grids, working systematically across or down, or in a more random way. After completing one or two of these they should notice the the patterns within each grid and how the tens remain the same going across the page and the units remain the same going down the page. This makes the systematic approach much easier. Go to our Addition grids, adding a single digit to a multiple of 10.
