A Number Grid is also referred to as 100 numbers, 100 chart or number chart. It is a visual aid frequently used with elementary aged children, to teach basic math concepts. At that age, kids often struggle to use numbers abstractly in problem solving. Number grids can help children recognize numbers, visually see how 10 based numbers are organized, learn to skip count and reverse skip count, learn the concepts of addition, subtraction, number order and sequence. Simply Number Grid is designed to help students develop mastery of these skills through games. Once the number grid is instilled in the child’s mind, they will have confidence and find the enjoy of math, which will help develop their cognitive skills and logical thinking capabilities.

These puzzles will really strengthen the kids number grid skills. They will master the number grid in their mind’s eye. The Number grids can also be used to further explore number patterns. For example, children can start at zero and count by 2s, when they are finished, 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. By identifying number patterns in grids, younger students build concepts for divisibility rules, prime numbers, and factoring which are covered in later grades.
