Educator Jonathon Holt says children learn best when they are actively involved. So here are free printable mini books, miniature coloring books and preschool activity booklets for children to color. Subjects in mini books include letters, words, seasons, animals, science, Bible, holidays and lots more. These coloring books make excellent preschool lesson plans for classroom and homeschool lessons for ages 4-7 years old. These free printable activity booklets are especially good for special needs children. To print coloring books, visit DLTK-Teach.
