Shouldn’t math textbooks be about teaching one how to use something before making a question so obscure that it takes a child and their parents about 2 hours to actually figure out what the hell the numbers are doing in each place? This is a family that is good at math. In fact at least one of the family members is a teacher and one of the others has a Phd in a field that required Phd level mathematics. Maybe ifÂ the book is trying to teach about Venn diagrams there should be practical questions that actually teach what Venn diagrams are for.
I understand that children need to learn how to think critically. I understand that not all things need to come easily. My point is that questions should not be so obscure in their meaning that you frustrate an entire family.
End Rant. (For now.)
