Help your student become a(n) Mental Number Line to 10

Activities ask children to use their mental representation of a number path and the relation between numbers up to 10 to solve a problem such as who is older, or what number is missing in a sequence (e.g., of connecting cubes "stairs" or in a "I'm thinking of a number" game.). Visual mediators (rulers and number lists) scaffold the learning in the earlier phases.
