This is Workbook 4 of Mandarin Hip Hop. In consideration of children’s mental development and academic achievement, at Levels 3 and 4, there is only one comprehensive workbook instead of the “Activity Workbook” and “Chinese Character Builders” at Levels 1 and 2, which maintains the features of the first two levels while increasing the width and depth of the exercises. There are various types of exercises for students to practice and reinforce the key points in the textbook and also systematic exercises on Chinese characters for students to practice character reading and writing step by step.
