These cards have bright colors, cute designs and big fonts. This makes them easy for children to understand and learn. They are great for toddlers and pre-schoolers to learn upper and lowercase letters, numbers and counting, basic shapes, common colors, sight words, basic objects. All these are very important and children are supposed to know them before kindergarten so it's important to teach them at home. I make it a fun game for my children and they love it. #discounted #sponsored #rankreviewbooster
