This booklet was designed for use with children aged 5-7 as a teaching tool that can be used both at home and school. Mathematical skills are presented in increasing order of difficulty, with each page building on the previous one, so that there is a built-in success factor. This success is presumed to convey the idea that learning mathematics is fun. Brief notes are provided for parents and for teachers. The focus is on basic facts of addition and subtraction. (MNS)
