Number, Color, and Recognition with R-21 For Ages 3.6 to 6 Years.
R-21 is a friendly green robot that helps preschoolers and kindergartners recognize and discern the differences in images to help strengthen their ability to count and recognize differences. The 24-page book is short, as is the attention span of young children, but is full of questions that not only teach but helps to increase the confidence level of young children.
I recommend because it’s a workbook that encourages and facilities learning in an easy and fun way. Parents participation is required, resulted in what I call quality time spent with my child . . . . . . . Mother of Two
