Numbers are used to record amounts or quantities. Learning numbers is essential for kids, because it is the very first step of a kid entering into mathematics, and it constitutes the most fundamental idea of that discipline. Kids need to be provided a lot of experience in learning numbers.

Between the ages of 2 and 4, most kids are capable of counting up to 5. By the age of 5, most kids are able to count to 30, and some of them may be able to count to 100. Besides counting, kids need to understand numbers, their quantity, relationships, and how they are affected by operations.
For young kids, 100 might be the biggest number they know. This worksheet helps kids explore more about 100 which is illustrated by number blocks. Compared with 1, kids can easily get the idea how big 100 is. The sheet also shows kids that 10 rows with 10 units in each row makes 100. This knowledge is quite useful to develop strategies for complex problems, such as 100 + 10 + 10 + 1 = (10 + 1) × (10 + 1)= 11 × 11 = 121. With this sheet, kids can practice counting, visualize numbers, connect numbers, learn basic operations, and develop strategies for solving complex problems. It is a great tool to promote their number sense.
