I'm reading over the Grade 8 Math curriculum for ideas on what to cover with my going-into-Grade 8 tutoring student next week, and I see the following:
"By the end of Grade 8, students will:
- evaluate algebraic expressions with up to three terms (e.g. evaluate 3x + 4y = 2z, where x = 1/2, y = 0.6, and z = -1)"
Clearly there's a typo, where "3x + 4y = 2z" should presumably be "3x + 4y - 2z". As written, it's an equation, rather than an expression... and worse yet, it's an equation that fails to maintain its equality (the left side of the equals sign is 3.9 while the right side is -2).
Similarly, a little further down, I run across:
"By the end of Grade 8, students will:
- solve and verify linear equations involving a one variable term and having solutions that are integers (Sample Problem: What is the value of the variable in the equation 30x - 5 = 10?)"
The problem with this one's less obvious, but still pretty annoying. The solution to the provided sample problem isn't actually an integer (as the description had claimed): it's 0.5, or 1/2.
Is anyone actually proofreading this stuff that goes out on the edu.gov.on.ca websites?
