I think students need a lot more practice in deciding whether compounds are soluble or insoluble than they think they do. I have made worksheets where the student looks at the name or compound and states "soluble" or "insoluble", but I thought this format would be just as effective and slightly more interesting. I'll let your students be the judge of that! I would use this worksheet as a homework exercise or an in class activity. Basically, the students will sort through a compound list and put the compounds in either a soluble beaker or an insoluble beaker.
