My Book of Number Games 1-150 is in the 'Math Skills Workbooks for Pre-K' series that covers ages 4-6. Perfect for children who can recognise and recite numbers from 1 to 150, 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 each number out loud, as well as matching each number and coloring in the blank spaces.
