Yarixta and Jessie are requesting a Subtraction Strip Board for their classroom. Using the Subtraction Strip Board, the child practices the equations of the subtraction tables 1-18. Natural wooden strips corresponding in length to the squares 1-18 are used to indicate the number to subtract from and 1 set of blue strips used to subtract with. A set of red strips is included for further explorations.
