For Grades 3,4,5,6,7 We are all in the same place!
Always study from the last lesson and move back.
The last lesson was on page 38 and 39, the letter Alef which is silent.
Once that is studied and practiced 5-7,minutes a day 4 times a week (for all at home practice) then review pages 32-37 where practice for the daled and vet and new vowel are.
Note: I know that your children have quite the schedules but without practice when they come to class unprepared and their peers have practice they feel behind. Happy students is what we love!
