Kids slide panels into view and learn basic concepts! This aConcept Slidersa book is filled with big, bright, color illustrations that teach toddlers how to recognize and name red, green, blue, yellow, orange, pink, purple, brown, and white. An amusing illustration on every page contains a pair of windows, one window presenting a small slide device that goes back and forth, and the other window located as part of an incomplete but easy-to-understand statement or a question. When kids move the slide device, they also move a word into the statement window. That word either completes the statement or answers the question for them. Here is an entertaining way for preschoolers to teach themselves fundamental concepts. Color illustrations on every page.
