Horizons Math Kindergarten builds the foundation for the method of study that is used all the way through the Horizons Math program. Every concept follows a deliberate pattern of introduction and gradual development. Each lesson begins with a new concept or an expansion of a previously covered concept. This introduction starts a cycle of repetition and review that students will experience as they work through the lessons. Horizons Math Kindergarten lays a foundation for order and exactness. The daily practice in the student books teaches the recognition and printing of the numerals 0 to 100. Simple addition and subtraction from 0 to 10 are taught. the addition-subtraction concept is extended through 99 with the aid of counters and the number line. Counting through 100 is presented by 1’s, 10’s, 5’s, 2’s, 3’s, and 4’s. Principles of place value, measurement, calendar use, telling time, graphing, comparisons, and money concepts are also introduced.
