Gimkits are a great warmup activity to use when you want to review a couple topics.
Here are some I've made, I've made many questions for each so they should be able to be played/repeated a number of times.
For the students beginning second JHS year, this should review things from elementary school up until the end of the first topic for second year - https://www.gimkit.com/view/6423719402c8520032c03975
For the students at the end of their second JHS year, this should review many things up until that point, including things learnt at elementary school - https://www.gimkit.com/view/63e57d830bf9080038aa2a9e
For the students at the end of third year, this reviews the entirety of JHS and many things from elementary school - https://www.gimkit.com/view/63cf71c882acda0036b7b519
Hopefully these should help you during the times where teachers turn to you when there's no textbook to do, or as a warm up.
All of these reviews concern grammar included in the New Horizons JHS textooks.
I'll continue to be adding to them bit by bit when a question enters my head.
These look fun.
Thought I'd let you know, in the 'Beginning of 2nd year' set, the image in the "How many circles are in the picture?" question is broken.
Oh, damn. I'll fix that, thanks for letting me know.
Naruot more famous than One Piece?! madness!
