These Montessori addition questions are for practicing independent work in math.
There are 10 static 4-digit addition problems with the control of error (sum/answer) included on the back of the addition problem so children really can work and check their work independently.
Many other command card sets do not include the answer on the back, which makes the child reliant on the teacher for the control of error.
The numerals are coloured according to the Montessori math hierarchical colors. The cards are numbered 'S1' (Static 1) through 'S10'.
Children can use these cards with Montessori materials if they wish. Suggested materials include stamp game, small bead frame, or golden bead material.
