This is a full version of Japanese verb builders (with answers) using Tutor system.
These resources allow a student to practice hight frequent verbs and to check their answers for accuracy themselves. It can be used for a wide range of students from primary school to high school. I have been using it for my students of Kindergarten through year 6. This is one of the popular activities in literacy groups. It is also a very good resource to differentiate the students’ activities.
