My Book of Number Games 1-70 is in the "Math Skills Workbooks for Pre-K" series that covers ages 3-5. Perfect for children who can recognize and recite numbers from 1 to 70, use this workbook to help children to further develop their counting abilities. Exercises include drawing a line from one point to another in numerical order while saying the number out loud, as well as matching each number to its same value and coloring in the blank space.
