Recording Addition on a Hundred Chart


I love having a theme and focus!  Recently I've written several posts about number talks and mental strategies for computation.  Check out Adding on a 120 Chart, Exploring Addition Strategies, and More Mental Math Strategies.  So far, I haven't really talked about the kiddos showing their thinking on paper--something that could be used for independent practice.  What I came up with was this little freebie for showing addition on a hundred chart.  There is one sheet with numbers included and another with spaces so you can add your own numbers.  Then I created two more versions with space for kiddos to show their work on on open number line, like I've shown in the photograph below.  Now, keep in mind that there is not a right way to show the work.  I jumped down 20, split the 8 into 7 and 1, used the 7 to jump from 73 to 80, and then added the 1 to get 81.  Another child might split the 8 first, use 7 to jump from 53 to 60, jump down 20 to 80 and add the 1 to get 81.  Yet another strategy would be to jump down 30 (a friendly number for 28) from 53 to 83, and then come back 2 to 81.

Click here to grab your freebie.  I'd love your feedback on this, so be sure to leave a comment!

    1. Thanks, Hilary! I'm with you--kids need to be able to explain their thinking in lots of ways, verbal and written.

  7. Donna,
    I am curious if you would use this with fifth grade students who still rely on their fingers to add. I would like to know your thoughts.
    Thanks

    1. Absolutely!! Kiddos counting on their fingers in 5th grade need all the number sense instruction they can get. I would even work with them on strategies for basic facts. Check out this post: http://mathcoachscorner.blogspot.com/2012/05/it-all-adds-up.html

  8. Donna, love this activity and will be using in class tomorrow with my second graders. Your ideas are so refreshing and really help the kids develop their number sense. I was wondering if you have any suggestions for a fun math station for a family math night that would work on number sense, but be geared to intermediate (4-6th graders). They still struggle with their math facts and I do believe it all comes down to number sense too..Thanks!

    1. Deb,
      Thanks for the nice comments about my blog! The older kiddos definitely number sense as well. Check out this post and see if that might work for you.

  9. Thank you soooo much for your resources and ideas! In my 3rd grade classroom, we use the addition strategies you've been sharing recently. I'm big on helping the students understand how numbers work and on using mental math strategies. I was wondering if you have any ideas how to bridge the gap with parents' "old" ways of doing procedural addition/subtraction strategies. I'm having a difficult time this year with my students insisting that "my mom said I have to carry the one" rather than using place value, compensation, friendly numbers, etc. and vise-verse with subtraction/borrowing rather than using a number line or counting up. I guess my question is how do I "teach" and/or share these strategies with my families in a positive and effective manner so that I can get them on board with the math their students are doing successfully in class and then going home and getting so confused with their parent's reteaching??? Or, how do I embrace these methods in the classroom as well to help my students understand what their parents are teaching them? Thanks so much for any advice!

    1. I hear this so often!! Unfortunately, we have to educate the parents along with the students. I would suggest communicating with them the research behind using multiple strategies and share with them what some of the strategies are. Maybe a parent night or a sheet you send home? As for the traditional algorithm, we teach it along with the other strategies. The idea is for the kiddos to have a variety of tools, and it's just another of the tools. Hope that helps some!

    1. I'm an empty-nester as of August when my son left for college, so I have some time on my hands! Actually, I just love doing it, so I make time. It's a better way to spend an evening that watching reality shows! Ha ha.

  18. Thanks for sharing your resources. This year I'm with my two kiddos at home and I do my things but it's very tiring. Your articles and resources give me ideas to work with them, and this one is awesome. I hope to use this one soon!! Glad to follow you on facebook. Many blessings!!

  19. Thank you so much for the freebie! My third graders, this year, are struggling immensely with adding and subtracting and hopefully a blank one in their working files will help them to get up and down the hundred chart a little better.

  21. I really like this way to show kids' thinking. We've been using the 0-99 chart in our district. Do you have this (or could you make one) using a 0-99 instead of 1-100?

    1. I'm sorry, Michelle/Gail, but I don't have it in 0-99.

  27. THANK YOU!!! I'm student teaching and I'm in my total teach! eeek! hehe and this just saved my life!
    I started with my 100th chart by adding and now I'm introducing open number lines,so this links perfectly:)
