Each unique book introduces a different letter of the Spanish alphabet, including ch, ll and n, and teaches letter recognition and letter - sound correspondence. Little books feature bold, colorful pictures and related basic vocabulary words that begin with the focus letter. Spanish alphabet and beginning phonics concepts are reinforced through hands - on phonics activities in the back of each book. In the activities, students use Letras y Dibujos (Spanish Letters and Pictures) Reading Rods, sold separately (LER7034), to practice matching letters with pictures that have the same initial sound. Color - coded text helps students differentiate consonants (purple) and vowels (green). Content, words and activities align with current research on how native Spanish - speaking children acquire literacy skills. Set contains 6 copies each of 28 different books (X and W are combined in one book; 168 books in all) and Teaching Guide.
