My son has hearing problems and since using RS, he now understands math and is not frustrated with it. ONLY RS has been able to help him. The other math, [other math program], is still sitting on my shelf and it never worked. Just the simpleness of saying 3-ten and 1ten-three helps him hear the sound difference instead of thirty and thirteen that sound soooo similar! To us it is a very small thing, but to a child with hearing issues, it can mean the difference of understanding math and not being so blasted frustrated and thinking they “can’t” do math. Yay for another success story in the making with a child’s understanding AND enjoying math.
