This is where the learning begins! Counting & Sequencing introduces numbers 0 to 20 one at a time through pictures, rhymes, and stories, so children can master counting each number before moving on. The fun activities help children recognize and count numbers 0 to 20 while also developing their sequencing and critical thinking skills, early reading comprehension, and their ability to follow directions. The six titles in the Basic Beginnings series are an essential and fun resource designed to nurture engaged learning for every child. Each book features 64 pages of colorful activities, mazes, and pictures, as well as three mini books to color, cut out, and share!
