It is always easy to give students something to compare but it might be difficult to let them share their own ideas about the things..
Besides worksheets, these questions that I -personally created and- asked in my online lessons to cover Comparison subject and make speaking practise at the same time might be useful for y`all.. At least you can check and understand what i was trying to do and come up with your own questions..
Student can use comparative and superlative forms as well `as ... as` and `too ... to` forms to answer..
Here you are..
I hope it`d help y`all..
