The Singapore Math textbooks for grade 8 start with exponents.

By exponential equations, I was referring to equations where the exponent is the variable. Singapore math does not start like that.

But the grade 8 Singapore math book is not Algebra I. It's more like IM.

No one else starts algebra I with exponential equations. I guess MCPS knows better.

How do you know that nobody else does this? And why is it a bad idea?

Best to learn how to work with variables before throwing them into exponents.

Exactly and look how hard it is even to raise the distinction in this thread without a muddle. There are basic terms to get straight before any discussion can begin. But this is also an example of the curriculum emphasizing qualitative math over computation.

Sure you can talk about the shape of an exponential graph just by plotting the integer points, but this sweeps a lot under the rug. To do algebra with the function, means studying the inverse, so that it's aiso possible to get the variable out of the exponent. The inverse function, log, is not introduced for another two years, in alg 2. And, again, that's in a qualitative way, just plot some powers of the base and get a feel for the graph of log. Then the following year, pre-calc, students do actual algebra and symbolically move between forms.

The OP may have better luck talking to the Teachers versus the Parents. Quite frankly, parents are kept (for the most part) in the dark as much as possible about their kids curriculum. Just don't know where that forum is?

There seems to be consensus around a desire for resource materials.

That is a separate problem with a different solution than a problem with the actual curriculum and material being taught.

Given that our nation ranks low in math, stories of parents not understanding the math worksheets that come home is not evidence that the current system is failing. It may be evidence that past math education systems failed, necessitating a new approach.

I am still not seeing the issue with the current system but I want to understand it and am open to being convinced because high quality math education is so important.

Facts bro, facts

Hmm why was it a bad idea to have a former PE teacher in charge of developing the curriculum? Its comical and almost as if they did it as a joke. Who could be less qualified? Gotta love that central office.
