Objective: Reading by Decoding Carefully read the words in your hand. Match similar word parts together to get rid of your cards first and become a reading ace! Reading Ace 2 is designed to help children aged 5½ to 8½ read more challenging words through decoding. The three card games it includes focus on three specific challenges: reading complex letter groups (e.g., ouille, ien), reading letter groups that are often decoded in the wrong order (e.g., cor for cro and vice versa), and not pronouncing silent letters.
