Callan Method. Student's Book. Stage 4: Lessons 41-60 - Robin Callan

Stage 4 is the second elementary stage of the Callan Method. In addition to many items of everyday vocabulary, students are introduced to the past simple of irregular verbs (e.g. "he drank"), future forms ("will" and "going to"), the present perfect (e.g. "they have eaten"), and the 1st and 2nd conditionals (e.g. "If you go …, you will see …" and "If you went …, you would see …"). This stage is appropriate for learners who are at A2 and early B1 level according to the CEFR.
