Moving from blocks to abstract, working on negative numbers. That is a big step to take. You don't see the wobble board she's standing on.
When Supremely Simple Subtraction landed on my computer, my world changed.
I have worked with students in different roles for 10 years. During that time I looked at, and worked with, dozens of math systems.
Supremely Simple Subtraction is revolutionary.
One of the students I tutor was diagnosed with dyscalculia when she was in 9th grade. Her biggest problem is understanding subtraction and negative numbers. In thirty minutes of imitating what Crewton Ramone demonstrated in his subtraction videos (linked in the Supremely Simple Subtraction manual) I was able to help her see how to subtract multi-digit numbers and make change.
Once she did a couple problems with the blocks, she was able to jump right into working problems on paper. She could "see" how the ones related to the tens and the tens to the hundreds and so on in a way she was never able to before.
When I quizzed her three weeks later, she was still able to make change.
The best part is how this helped her confidence. She no longer has to hide the fact she can't subtract. That has been HUGE in her life.
