The purpose of this instructional packet is to inform teachers and parents about children's development of numeracy in the early years of schooling. "I Can Do Maths" questions are in a child-friendly format and require children to write, draw, count, and measure. Two "ezi-guides" are provided to make administration easier. Keeping track of the results of assessment can be time-consuming. To minimize this, the Individual Student Profile, Diagnostic Map, and Descriptive Report are provided to assist teachers. All of these provide descriptive and normative reports of children's performance in number, measurement, and space, not simply a score, so that planning a teaching program appropriate to an individual child's needs is made easier.
