When I explained this to my second grade daughter, I used the idea of counting up to make change. First count up to the nearest ten, then further by tens then any extra ones.
She seemed to enjoy this concept and really understood what she was doing.

Agreed! I also think that the counting up and down aspect, as it relates to subtraction like it mentions in the quote, is another strategy to help build the understanding of "the difference." There are different names for counting on by different place values, but they all use the idea of starting at the first number and taking a series of jumps up to the second (on a number line) and tracking the total jumped to find the difference. All of these are to help build better understanding so that they can better apply the standard algorithms when they learn them, as well as a better use of mental strategies.

Prevent DUI with rigorous math tasks! Awesome.

Re: 2nd Grade bundling and skip counting. Skip counting is transitional in the same way 2nd grade algebraic solving is transitional. Skip counting progresses to more to arrays and multiplication, more complicated series, sequence and growth and the other to advanced functions and algebra, I think they both intersect nicely in 8th grade and Algebra. I would hope there is no unlearning, just developing, especially since the entire grade is focused on place-value through grouping, ungrouping and

"The teacher asked Sally to count from 176 to 214, as part of the standard where we are learning to mix counting by ones, tens, and hundreds, getting us ready to subtract down the road...."

There is something not right about the question. It's about a transitional process that we do not expect children to retain for long.

One of the most powerful things about teaching children mathematics is that we do not have them unlearn things later on. I believe this question, by focusing on process at an inappropriate moment, manages to fall outside of that.

I think there are a couple of acceptable answers, but not all are necessarily acceptable for a 2nd grader.

I *think* the purpose is for students to develop a deeper understanding of numbers. I.e., if Sally were trying to figure out how far it is from 176 to 214, there were 4 ones, then 3 tens, then 4 more ones. So, that correct response for a 2nd grader might be that Sally was trying to count from 176 to 214 and see how far apart they were, keeping track, perhaps, on her fingers.

An alternate response, though I wouldn't expect this from a 2nd grader. Sally was pulled over by a State Trooper for suspected DWI. Sally was asked to count from 177 to 214.

My first thought was about why the authors of the question used the word ?between?, which would exclude 100 and 220 ? unless that was the intention. I wonder if that is a distinction that a 2nd grader makes given that most adults can?t either.

My next thought was about what ?counting up and down? entails. It doesn?t seem to me to be very specific. Must the counting be with the set of counting numbers (whole numbers) used consecutively starting at some point? In fact, the only problem I see is that Sally counted only up in her fashion. She did use ?ones and tens?.

I was recently given a problem from a worksheet from engage NY ? on ?counting up and down between 100 and 220 using ones and tens?.

A question on the worksheet was as follows:

Sally did some counting. Look at her work. Explain why you think Sally counted this way. 177,178,179,180,190,200,210,211,212,213,214

Given that this was for a second grader, can someone share with me what the objective(s) was for this question? what is an ?acceptable? response?
