About Blank Number Line

Together Roamer and Number Lines provide students with models of arithmetic.  For example, older pupils might learn a rote rule like, “Two minuses are a plus”.  If they use Roamer to explore a Number Line they focus on key mathematical ideas: what is a negative number; what is a positive number; what does subtraction look like. Instead of learning a rote rule they gain a visual, spatial and kinaesthetic understanding.

On one side Number Line has 11 squares numbered 0 to 10.  The other side has numbers 0 to -10.  If you put two together you get a -10 to 10 line.  The Line provides Roamer with a durable nonslip running surface. Forward 1 moves Roamer to the next square.
