The demands of basic math skills often limit the ability of students with autism spectrum disorders to master purchasing skills. This study examined the use of counting-on math skills in conjunction with the next-dollar strategy to enhance independent purchasing skills. Four students with autism and intellectual disabilities successfully acquired and generalized counting-on and next-dollar skills to community settings. Students maintained both skills at a 100% level for up to 6 weeks. Intensifying instruction on functional skills that builds on basic academic skills represents one means of accessing the general education curriculum. (Contains 4 figures.)
