Here is a starter kit for learning colors. Initially, it focuses on primary colors.
Thanks to the mini-books, children can explore the entire universe of a specific color while developing their language. The mini-books are designed for the size of little hands for better manipulation.
There is a mini-book for each primary color. The front cover is customizable, and there is an index on the back cover.
Using the same elements, I created posters (one for each primary color). The child can pick a card and place it on the poster in the corresponding spot. This is both a visual discrimination exercise and an eye-hand coordination activity, all while enhancing their language skills.
