Schultz's boards that are special boards. We practice with them the proper muscles of the eye ball, which gave us better field of vision.
Looking on the number in the middle of board, try to see rest of the numbers (don't take your eyes off from the centre [red font]). To raise the difficulty level, you can e.g. try to put the numbers in order from the smallest to the biggest number. Of course during this exercise you also can,t take your eyes off from the number in the centre.
