A child asked me to help with the problem below:Five plates and two cups cost $34. Two plates and five cups cost $22. How much is the cost of a dozen cups?_______While I know how to solve it using simultaneous equations, I want to know if there's a method that could be easily understood by a 7-8 year old.
The training in Colombia was amazing! I can't wait to start using the method! Thanks Mei!!
Day 2 in Columbia - participants getting confident and competent in using the model method to solve problems.
