Hello-
I searched google.com for TRIPLE PLAY PLUS and got many hits. It appears to be a CD-Rom that you will have to buy. It looks like it costs about 99 dollars. Maybe your school's budget can manage this? Hopefully you can get a professional discount.
I searched google.com for
"free games" download "english grammar" and got many hits. Below is the link to one of the pages I found for you, but if you
repeat my google search [LINK] you can try looking at many more of the other web pages too.
This web page (link below) contains many interactive computer games that you can download for free. These games are intended to help your students improve their English language learning skills.
You may need to download the free
shockwave software from Macromedia to play the games. There is a link on the web page to the place where you can get the free shockwave plugin. Try playing the games first and if they work then forget about shockwave.
This page has these 18 downloadable games for primary school (or beginner) English language students: Find the missing building, Drag and drop game, Look and write game, Reading English game, Read and write English game, Complete the crossword game, What do you do on Sunday?, Complete the sentence game, Look and write 'It's', Find the animals game, Find the English words, Connect the dots game, It's a ____, Write 'can' or 'can't game, Colouring in game, Counting game, What time is it in English? and Write the price game.
18 FREE English teaching games to download here [LINK]
I downloaded game #13 (What time is it in English?) to test it for you. The .EXE file was about 360 Kb, downloaded quickly with no demands for registration or money, AND when you execute (double click) the file it just runs the game immediately with no installation, which is very good news. So, I can now recommend that you can safely download and test all 18 of these games.
Don't forget. If you download a game and it will not open for you, then you will have to download the shockwave file from macromedia. There is a link to the page where you can get shockwave at the games download page.
I hope this helps.
