Rather than continue with new spelling words each week, my 5th grader will revisit previous lists and do definitions, sentence writing, find the nouns and verbs, and alphabetical order. This serves many purposes all centered around one group of words each week. She too will be tested weekly on these words.
DJ will also be doing the ACT Question of the Day, and the SAT Question of the Day, each day. This is a great way to practice and prepare for these tests. There is also an app that I love it is shown below. The first one is free, and the one we use. The second is not free, and I have never used it. I have Android phones, so any apps I share should work on Android phones, but be sure and check first.
