Explain how you can use a model to find 6×17

Well, you could use a concrete model to make 6 groups of 17 objects. Then, you could count them.

You can use an area model or partial products. 10 times 6 = 60 and 6 times 7 is 42 so just add them up

Photography has changed its subject matter quite a lot over the past few years. in the 1800's, it was considered normal for families to have  post mortem photos of their loved ones, and now that would be completely unacceptable. i think that photographers have always pushed boundaries and have been eager to capture everything, it is just society that changes their boundaries.
