I've made a review for Units 3,4,5. It does not cover the entire units, so change accordingly.
It's formatted as a sort of scavenger hunt so that students must actually look through their books to find the answers.
My students are intermediate level and I think this should take about 35 minutes. I haven't used this yet, but a similar review sheet worked well for grade 1 middle students.
Pair students into partners and the first team to finish wins a prize. In my case, they get temporary tattoos.
