NACD Math was designed not only to teach children how to do math, but also to help them learn that math is easy, that they are good at math, and to enjoy it.

NACD Math is now made available online for our NACD clients through the NACD Family Portal. The new updated NACD Math replaces Modular Math, as well as supplemental math books.

Lyn Waldeck and Sara Erling, along with John McCallum, have been working for the last two years to bring together the pieces of NACD Math. NACD Math is targeted for the special needs population, particularly for those children with Down syndrome, those on the autism spectrum, and children with learning disabilities who have historically had difficulty with math. The program has also been used with great success for typical children to establish initial math concepts and to teach them math processes from initial number and quantity concepts through sixth grade computation.

NACD Math has a long history of development and has been used with thousands of children internationally.

Math education for special needs children has been an issue, except for those who have been using Bob Doman’s Modular Math program. The reason our program has been so effective is that it is built around how children learn, whether they are on the spectrum, have Down syndrome, or simply are young. Historically math instruction requires a lot of words. A lot of words are not something any of these children process or understand well. Our math program is very visual and teaches the child just one step at a time; and it is designed to avoid the need for, or dependency on, prompts.

NACD Math has been designed so that virtually anyone can teach it. The program incorporates video step-by-step instruction, so the teacher, parent, or even a sibling can watch a short video and then replicate/teach the simple steps. Each math computational process builds on the previous processes, creating simple transitions from one process to the next.

NACD Math has permitted many hundreds of children with Down syndrome to start learning math even before their typical peers and often to stay ahead of them for many years. With the solid NACD Math foundation, children with DS have been able to move into algebra and higher math. To say that NACD Math has been helpful for this population is a gross understatement; it has been a game changer. NACD Math builds a math foundation and understanding that has permitted special needs children to advance into higher math and has established a foundation for typical children that gets them off to a running start and puts them way ahead of their peers.
