This digital learning kit pairs songs in MP3 format (teaching subtraction facts with minuends to 18) with a reproducible PDF resource book filled with activities and exercises, reinforcing what has been learned in the songs. While the focus of this learning kit is the teaching of subtraction, supporting activities also support the new Common Core Curriculum for Mathematics including: pattern recognition, dates, time, fractions, doubles, shapes, coordinates, reading graphs, ordinal numbers, Roman numerals, temperature and money. Includes a complement of self-quizzing MP3 tracks allowing students to review and quiz themselves.
