From: Onder To: Teacher2Teacher Public Discussion Date: 2007102220:44:26 Subject: Criss-cross method I don't like this method because when it comes to multiplying fractions, they tend to cross multiply and mix things up. Also with this method they are not learning why they are cross multiplying. With LCM then tend to see the purpose behind what they are doing better. My 2 cents.
