Abstract
This study apply document analysis, concept mapping, focus discuss group, and questionnaire to construct about mathematics learning outcomes indicators for 5 years old children. Study team invited scholars and experts to hold over ten times seminars, then take many advices. Questionnaire was developed according to importance and suitability of indicators and considering about implementable and measurable of operation definition. Analysis of 593 questionnaires, set agreement percentage lower 80％ are deleted, find that mathematics learning outcomes indicators will discriminate three items. First, number and amount include 5 sub-items. Second, geometric and spatial include 2 sub-items. Third, logical reasoning include 3 sub-items. Overall 9 sub-items have 26 indicators. Results in this study can provide a valuable reference for pertinent authorities in education decision-making.
