[quote=Anonymous][quote=Anonymous]Kids with learning disabilities get very confused by being taught multiple ways to solve problems like this. Just teach them one way that works for them. I understand the need for number sense, but if your child gets confused, just stick with one way. [/quote]

+1  It's good to know how to solve something 10 different ways as long as they also know a single consistent, fast method.

I have a rising 5th grader who struggles in math and she once was told to pick her favorite way to solve 14*12. Unfortunately, her "favorite" was to add 12 fourteen times because she didn't really understand what we would view as the standard multi-digit multiplication algorithm since it was presented as just 1 method out of a bunch of different ones, not the default. Her other favorite was lattice multiplication, which I tend to think of as a cool trick but realistically wouldn't be super efficient for solving 14568*459, for example. But the teacher never told them to pick just one and practice it for speed and fluency, so nothing ever really stuck.[/quote]
