Nelson (early childhood education and Montessori method, Bridgewater State College, Massachusetts) presents approximately 100 activities to encourage early childhood number sense and math skills. The mostly hands-on tasks correspond with the goals of increasing awareness of stable quantity, counting, recognition and writing of numbers 0 to 9, connection of numerals to quantities, and part-whole awareness. The final section discusses the teaching potential of commercial games such as Mancala, and reproducible materials are included. Annotation ©2008 Book News, Inc., Portland, OR (booknews.com)
