Teaching with the 20-Track

The 20 Track provides the children with an introduction to the number line and affords the child the opportunity to discover addition facts for numbers 1 to 20.  Children can also see how the structure of the addition facts they learned about numbers 1 to 10 has a similar structure in the numbers 11 to 20.  The number track also helps in grasping the bridging facts.
