If you have already been learning characters for a while, this is a great place to review. Each lesson below covers a group of characters that share a common component. It is helpful to approach characters this way at the intermediate level when you want to review and/or extend your character base. Each lesson is carefully crafted into a uniquely illustrated meta-story, which also helps the brain associate new characters with a group of similar characters. You can also find Utah DLI (Dual Language Immersion) characters grouped by grade level, so immersion students using Mandarin Matrix can consolidate characters they are learning in school in a new way.
