Our daughter took to the D.I.V.E teaching style quickly. We cover pre-algebra in half the time. She is retaining what she is learning and I am very pleased with the improvement in her note taking skills.
We received the cd-rom with book purchase and love it! It is so helpful to have him teach the lesson then have the text with full explanation and examples as well. I have switched from Math-U-See to Saxon this year and am very, very pleased.
