Disappointing experience with elementary education in USA

After our move to Oakville, ON , we have had multiple reinforcements that our disappointing experience with elementary education in Ontario is not dissimilar to other US ex-Pats utilizing the Ontario Public Schools. Also, we have been told by multiple Ontario teachers, who taught in the US, that the Elementary program here is weaker, especially in Math. We have learned that many of the Private schools use a curriculum more typical in the US and to do so, utilize the text books for a higher Ontario grade..ie: the Grade 6 private school children use the Grade 7 Ontario Math public school text book. From our findings, the Ontario private schools offer a curriculum that is greatly enriched from the Ontario public schools and more inline with the expectations of American schools we have experienced.
