These friendly frogs will guide the primary students to count from 1 to 100. Once assembled, this product can be laminated for use year after year. Odd and even numbers are given alternating color backgrounds for easy recognition. Multiples of 5 show in blue and multiples of 10 display a lily pad instead of an individual frog - noting that a 10 stands for a special group, like how the lily pad could hold the group of frogs in that group of ten. **Feel free to contact me if you'd prefer a number line with a different theme, or one using graphics of your own. Happy Counting!
