I have to give three 40 minute advanced lessons a week (grades 5-6). It's by far the part of my job for which I have to do the most work. Anyway, after a couple of months of scrounging off the Elementary Level Master Index (
http://waygook.org/index.php?topic=7649.0 - thank you!), I'd like to contribute.
Here's a variation of a battleships game I tried out yesterday and which was very successful, so I tweaked it a little to allow the kids to play in pairs.
Yesterday I gave each of the kids one of the sheets, and they had to pick 10 boxes and mark them with an 'X'. I would then read off 15 sentences (pre-written, to avoid accusations of favouritism) and if they'd predicted any of my chosen sentences correctly, they circle that box, with the idea being to get the most answers in sync with mine. Basically, a larger version of bingo, with candies as incentives. It's good listening practice, as I would occasionally complicate the sentences and hide the answers within what I was saying.
So tomorrow I'm going to do a similar thing but in pairs, and more closely resembling battleships, to get them speaking as well. They each get a sheet and fold the top half up to hide their grid, then mark 10 boxes. They take turns to ask questions, hoping to find their partner's 10 answers first. There are three rounds (body parts w/ descriptions, weather, and dates / ordinal numbers) and you can just edit the grids to relate to other topics. If it's successful, I'll try it out with 5th grade lesson 7 too.
