Help desk - is this question worded properly?


This problem is from Engageny math. Here's the sheet I assume it appeared on. Grade 2 - Module 3.

Here's Andrew Gelman.

Speaking as a writer, and as a parent who spent a lot of time teaching my son and myself grade-school math, I don't like the wording at all.

"Sally did some counting" ---- the word "count" means count by ones, especially to a 2nd grade child.

Plus the question about why Sally did what she did invites commentary on Sally, not Sally's method.

Is there a way to ask this question that makes more sense?

And is there a reason to ask it this way -- to ask a student to analyze Sally's answer -- rather than to ask the student to use 1s and 10s to count up to 214?

I have to say .... offhand, I see no reason to ask this question this way.

I would much rather see this as a story problem about giving change.

Sally has pennies and dimes in her pocket.
Her friend Jane sells her a glass of lemonade for $2.14.
Sally gives her $1.77.
How many more pennies and dimes does Sally owe?

That wording doesn't produce the specific sequence, of course ....

What if you just said, "Count up from 177 to 214 using the fewest (whole) numbers you can. You can count by 1s or skip-count by 10s."

Here's a question.

Does "skip counting" by 10s only mean 10, 20, 30, etc.?

Can it mean 177, 187, 197?

engageny is a full curriculum, I think

I noticed in the Comments thread for Allison's post people talking about whether engageny is or is not a full curriculum.

I think it's intended to be a complete curriculum (but I could be wrong).

Last fall my district replaced Math Trailblazers with engageny and nothing else. The curriculum director told us that they'd saved roughly $100k by going with the NY state curriculum (which had not been written when they adopted it).

I mentioned in the comments thread that, a few years back, I went to a talk by David Steiner, who said that the state was going to write a complete math curriculum states would be free to use or not. He didn't say anything about writing a supplementary curriculum. The plan was to write a complete curriculum districts could use instead of a curriculum they'd purchased from a textbook company.

I think what they've posted is the result.

Here's the wording from the website:
In order to assist schools and districts with the implementation of the Common Core, NYSED has provided curricular modules and units in P-12 ELA and math that can be adopted or adapted for local purposes. Full years of curricular materials are currently available on EngageNY, for grades Kindergarten through 9th grade in Mathematics and Kindergarten through 8th grade in English Language Arts (ELA). NYSED is working with our partners to deliver high quality curricular materials for all remaining grades in both Mathematics and ELA. In Mathematics, full years of instruction will be available for all remaining grades this summer. In ELA, full years of instruction will be available in 9th and 10th grade this summer and 11th and 12th grade this fall.

Common Core Curriculum
They've posted 105 lessons for Algebra 1.

I counted.
