U.S. editions teach metric (what your child needs to know) AND the U.S. Imperial weights, measures, and American money. Singapore and U.S. terminologies and names are inter-changed throughout but concepts, skills, and actual numeric and word problems are the same in each version.
Units highlighted in red are in this U.S. Edition but not in the 3rd Edition of Primary Mathematics.
