Did anyone want to throw in the towel when they realized our second and third graders were expected to "decompose numbers in more than one way"?
No? Just me!?
I don't buy it; you weren't too fond of this concept either. After all, those of us who taught older students certainly inferred that students were already struggling with place value in their younger years because when they show up in 4th and 5th grade, they're exhibiting misconceptions with place value. I remember sitting with some teachers in our first PLC before the school year began a few years back and deconstructing the following TEKS:
Use concrete and pictorial models to compose and decompose numbers up to 1,200 in more than one way as a sum of so many thousands, hundreds, tens and ones. (2.2A)
Compose and decompose numbers up to 100,000 as a sum of so many ten thousands, so many thousands, so many hundreds, so many tens, and so many ones using objects, pictorial models, and numbers, including expanded notation as appropriate. (3.2A)
I'd like to submit, however, I believe this NEW standard will significantly assist our students with building a stronger foundation in mental math and their ability to fluently manipulate numbers as they develop in math.
