Our pack includes 1 book and a set of 2 flashcards designed for children aged 7 and above. The objective is to help them master basic operations through written and oral activities. Our innovative COQUITO TABLES system teaches children that when they learn to add, they also learn to subtract. Similarly, learning how to multiply helps them understand division. Our tables offer not only traditional practice but also evaluation exercises and reasoning exercises. These exercises include diagrams and images that help children with mental calculation. By completing the third reasoning exercise in our addition tables, children can also learn subtraction since it is the opposite of addition. The same goes for division, which is the inverse of multiplication.
