For students who want to prepare to go back to school but only have a few minutes to spare each day, I would suggest making a plan. For younger students, a parent can organize a set plan for which subject to review each day of the week. For instance Monday: 15 minutes of Reading Comprehension Tuesday: 15 minutes of Math facts Wednesday: 15 minutes journal writing etc. If a student struggles in a particular subject more time should be spent in this area. Every little bit helps. 15 minutes of reading a day is better than nothing. As well it is important to remember that reading is reading regardless of the medium. Reading a comic book still counts as reading. Allow students to read what they enjoy. For older students I would even suggest unofficially quizzing yourself/summarizing what you have learned each day. For math, search online and find fun puzzles or math games online. All in all make it fun and it won't feel like a chore.
