P.J. here, I wanted to let you know that I made the baggies with the #'s of digi blocks in them. 10 baggies of each. 34, 52 and 45.

Thanks, P.J., I'm anxious to try them out at our next meeting. Here is the lesson so far. Please edit any and all. Also, here are the Guiding Questions for Developing the Lesson. Please use them to check over the lesson and see if we have maximized learning. Thanks for some good conversations. The lesson will be taught Tuesday, May 17.



This is Gary Elkins. This is my first post and I hope I am doing it correctly. :-)

I love the topic that you chose! Building understanding of the place value structure is so important and sadly, as you stated in the lesson, unpaking numbers is seldom seen in the primary classroom. I read through the lesson and guiding questions and think it looks great. I couldn't think of anything to add at this point. Pine Trail teams are always so t horough in their planning and execution which makes for a great model to other schools and a thrill to observe or participate in. I apologize for not being more involved this year, but please know that if you have any questions for me, don't hesitate to ask. Please let me know what time the lesson will be on the 17th. I do have other meetings that day, but would love to be there if I can. Thanks! Gary

Hi, all. Two minor suggestions for the lesson plan. (1) use the phrase "relationships within the place value system" instead of "relationship between place value" and (2) another way to prompt decomposing 10 is to ask the child if he had a dime, is there another way he could have 10 cents that he coudl show with the blocks. This lesson focuses nicely on just pv-based ways to represent a number. It will be interesting to see whether kids remember when they first meet subtraction with regrouping. (Of course I know this will not be their only experience with it.) I haven't seen digiblocks but am assuming they arrive with the vocabulary of "unpacking." How many words are out there now: borrowing, renaming, regrouping, decomposing and now unpacking. Personally, I will stick with decomposing. I don't think unpacking brings any additional meaning or constraint than decomposing has, which is part of Common Core and all through the research. If the intent is limit to place value allyou have to say is use the blocks in all the different ways you can to show this number. I'm thrilled that your goals contain two of the math practices from CC!

These are the worksheets. Please scrutinize them and let me know if changes are needed.

Pj Here,

Thank you, Diane, they look good. One thing I think we already mentioned but is not in the lesson.

With the 52 worksheet we say there are 6 ways. With the 45 worksheet, will we mention 5 ways? Even though it has 6

ways on the worksheet. Or should we change that?

I also noticed a typo at the end of the lesson. Last question about the 100's digi blocks. Do we just edit it?

Hi everyone, Pj again,

I was going through the lesson and started to think if we need to give directions for the students to put the 34 back

together after each time they record a new way. If not it could become a bundling lesson if they find 34 ones first.

They will be putting 10 ones together to get the other ways. :( ?
