Presentation
- The directress sets up an addition of two numbers, and the child completes the sum, placing the corresponding bead bars in their places.
- This equation is correct.
- The directress switches the places of the two colored bead bars. Is it still correct? Perhaps it was a coincidence; let's try another.
