A number grid is crucial to learners as it helps them to get a clear understanding of numbers and how they work. Also, is a tool which assists learners to be able to count and solve mathematical problems which they can't solve by themselves. Number grids can be used to explore number patterns. For example, children can start at zero and count by 2s. If they color each box as they go, they will have colored all the even numbers. If they start at one and count by 2s they will color all the odd numbers. If they count by 5s, starting at zero, they will color numbers with 0 or 5 in the ones place.
