I am looking for the conceptual/visualisation way of tackling the algebra problems . I found that Singapore Maths caters this need. What are the good sources for Singapore Maths - any online classes for Singapore Maths. My aim is to mentally solve any word problems - algebra so that I score high marks in the competitive exams like GRE. Also, This way I can crack the algebra problems visually rather than x, y and z.
You asked about online classes for Singapore math. I realize you may no longer need this info, but thought someone browsing the questions might appreciate it.
I recommend the courses at ed2go There are two classes one for 1st-6th and one for 6th-9th. The courses are given repeatedly for 6 weeks cycles and are under $100 They will break down all the steps needed to problem solve with model drawing from the simplest to fractions, ratios, percents, and more.
I took this course before I started teaching Singapore math and it really helped.
