I'm just writing to express (again) how much I love the ladder method! :-)
Last spring, I wrote a guest post about the ladder method on Rachel Lynette's blog, so if you're interested in reading all the details, check it out.
Otherwise, the latest ladder method item I've created is a new poster/anchor chart. I had a few different ones last year, so I decided to consolidate!
The link to my ladder method fold-it-up is below, if you'd like to download it.
What I really like about this method is that the process is the same for each use, but the outside numbers are used differently. I like the fact that the continued use of the ladder method (for various reasons) leads to the students making greater connections between numbers.....finding factors seems to come more easily.
I haven't shown the students how to reduce fractions using the ladder method, but they'll see it on the poster next week. Then when we discuss fractions, it will already be there!
