Yes, I used it with both my oldest and my youngest dss. It is excellent for an LD child because it focuses on only one skill at a time, and shows pictures of each concept which you can easily duplicate with physical objects. It is very concrete and also has the added advantage (for some children anyway) of being very plain--it's printed in black plus one color, not flashy, and with no distracting pictures or info boxes. I hope this helps; you can email me at mamag_55992@yahoo.com if you have more questions or want to know something specific.
