patterns are in essence numbers. its a good gateway into math. if you can get his interest with legos, blocks, tinker toys, etc, that will help build math skills. autistic children are often very visually oriented and fascinated by patterns. my 5 yr old autie is as well. its not something we've ever tried to curb. in fact, we've always encouraged him to be interested in patterns, which turned into an interest in counting, which has developed into excelling at math and easily doing 1-2 grade work even tho he is only in kindergarten. the only downside is when he insists we count to 1000 with him.
i actually just bought this for my son. its a bit young for him, but he still loves to make patterns out of things, and i thought he'd like the colored shapes to do so.
speaking of math, i have to share this about the Fibonacci sequence, its a gorgeous video, lots of lovely patterns and numbers:
