Hello, I have a quick first grade math question. I am switching from Kindergarten at a private school to 1st grade at a public school. I have been getting my lesson plans ready for the year, and I am wondering about the 1.G.1 standard for math where students need to distinguish between a non-defining attribute and a defining attribute. I was going to teach them those terms, but my husband thought that was crazy. I looked at EngageNY and noticed they don't use the terms defining and non-defining in their lesson plans. I have noticed other teachers on TpT do use the terms. Can any other 1st grade teachers give me their thoughts? What do you or your math program do? Thanks!!
