Twice as Many

Clip to ScrapBook #1

Many of my students are confused with the term "twice as much". For example, Joe has 5 coins. Jane has twice as many coins as Joe. How many coins does Jane have? This most of them can understand, but when I say Jane has 10 coins. That is twice as many coins than Joe has, they get all confused. Any suggestions? Any good picture books out there that you know about that may help? Thanks!

Try using a mirror. Have students put a number of counters down and then place a mirror next to the counters. You will have a double and twice as many.

I'm not sure what grade you teach, but I tell my students (3rd) that twice as many is the same as 2x or double.
