Available in paperback, one volume for each year Pre-K through 4th Grade. Workman Publishing Company, 2008; ISBN and page numbers vary by volume.
I initially ordered these books -- Pre-K and Kindergarten volumes -- online. They are well-organized, beautiful and much larger than I expected! Each workbook contains a wonderful variety of projects and activities for all different learning styles. The full-color pages appeal to children and parents alike.
The Pre-K volume (320 pages) covers beginning phonics, letter and number formation (with tracing and practice pages), colors, shapes, matching, mazes, "what doesn't belong" and more.
The Kindergarten volume (320 pages) covers phonics, letter and number formation (with tracing and practice pages), beginning reading, sorting, money recognition, telling time, patterns, matching, mazes and more.
Final Thoughts: EXCELLENT. These are not curricula for homeschooling, but rather great supplemental resources for vacations or to reinforce regular school studies.
