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!
Love this!!! Thanks for the freebie:) -Jill
ReplyDeleteMy pleasure! :)
DeleteThis is great. Loved how you used the open number line to show thinking.
DeleteLove the open number line!
DeleteI love this! I am always looking for ways to help my kiddos explain/show their thinking in math! Thanks so much for the freebie! I can't wait to try it with my kiddos! :)
ReplyDeleteThanks, Hilary! I'm with you--kids need to be able to explain their thinking in lots of ways, verbal and written.
DeleteThanks for the sharing! I love the concept to easily help give a visual for the addition set...
ReplyDeleteThanks, Heidi!
DeleteThis is perfect for my upcoming lessons!!

Oh good!! Glad the timing worked out so well. :)
DeleteTeaching this tomorrow to be exact in my Envision lesson, thank you! This will be great to reinforce the lesson and to be used for practice. Thank you very much!
ReplyDeleteWell, how perfect is that? :)
DeleteI'm going to share this with my 2nd grade teachers. I'm sure they'll love what you have to share.

Great!
DeleteDonna,
ReplyDeleteI 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
Dianne
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
DeleteDonna, 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!

Deb,
DeleteThanks 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.
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!

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!
DeleteI love this! I am vary anxious to see my students try this so I can really see their thinking patterns. Thanks for sharing! I really enjoy reading your blog and newsletters! How do you find the time?
ReplyDeleteThanks!
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.
DeleteThank you so much for sharing this Donna! I am using so many of your wonderful ideas and activities in my classroom and am so grateful to you for sharing your knowledge! I really look forward to all of your new posts!
