Did you know that Khan Academy just released the first version of reading comprehension practice on Khan Academy? And, it is grouped by grade level:
Khan Academy recommends starting at your grade level and doing 1-2 practice sets per day (or 10 practice sets per week). This should take about 10-20 minutes per day. If you find it difficult, completely okay to start at an earlier grade level. Likewise, if you find the passages and questions to be easy, feel free to move to higher grade levels.
Khan Academy also has a grammar section: https://www.khanacademy.org/humanities/grammar
Khan recommends starting by taking the course challenge a few times to figure out what you know and don’t know.
This is a great way to practice reading comprehension & grammar while you’re learning at home! Challenge yourselves! Enjoy!
