First off, let me tell you how much my students and I all love the SMATH program. We have been using it since September and the students manage the centres like pros! I only gave 4 stars for this resource, because I am not really a fan of mixing time and addition/operation. Some of the questions are a not really applicable to real life. Eg., mom is x number of months old, dad is y number of months old, how old are they altogether? Not really something that has real meaning even though we can calculate it. I was hoping that the addition/subtraction unit would be universal and perhaps include problems from a variety of strands. Regardless, I still like that it uses key words that help the students figure out if they should add or subtract. I love the program overall, but this is not my favourite unit.
