Monster ABC guides your child in a really fun way through the process of literacy acquisition. It helps children get to grips with letters and the initial sound of words in the best way possible. WHAT IS AN INITIAL SOUND? Today, little ones use initial sounds to navigate the first stages of literacy acquisition. An initial sound is the first sound of a word and is represented by a letter or a letter combination (like “mm” in the word “mouse” and “sh” in the word “sheep”). Children learn how to make out the initial sound of a word and match it to a letter.

Each picture represents a word whose initial sound must be matched to the corresponding letter. If the initial sound and letter match, your child will enjoy a true sense of achievement. In doing so, the child easily recognizes the correct combination of initial sound and letter. The learning process is supported interactively with visualizations and sounds that are perfect for children. • In addition, a free-of-charge initial-sound table, featuring pictures and their matching initial sounds from Monster ABC, can be downloaded from the wonderkind website: https://s3.amazonaws.com/wk-anlaute/wonderkind_initial_sound_table.pdf • Monster ABC was developed together with grandparents, parents, and kids, taking into account professional pedagogical and linguistic considerations.
