So i just want to say that i agree with you, but i have some other things to say about this too. First of i would love for the longs, (or ten sticks,) should be able to be taken apart. It would help kids to understand The topic better. However, i don't think that base ten blocks are made for subtracting. If you want to add, then just stack the ones up by the tens, and show how you can add that. Although it would be helpful to have them connect, and come apart, I don't think that you have to trash them. Because they may be good for other things.Anonymoushttps://www.blogger.com/profile/10864404735982145052noreply@blogger.comtag:blogger.com,1999:blog-5699949251277141058.post-1910174950093849982020-02-12T08:16:35.485-06:002020-02-12T08:16:35.485-06:00Hi Stacey!

While I don't have research (other than experience! :) ) to back up this exact idea that base 10 blocks are less useful than manipulative ten groups, I do have research I base my math instruction off of. It comes from this book, Children's Mathematics (affiliate link): https://amzn.to/2HjJHtT<br /><br />This book talks about Cognitively Guided Instruction which is just about teaching the way kid's math brains learn. It's discovery heavy instead of giving everything to the kids (which is why I use buildable 10 groups instead of fixed groups like base 10 blocks).<br /><br />I hope that helps! Feel free to email me if you have any other questions!<br />Whitney :)<br />thefirstgraderoundup@gmail.comWhitneyhttps://www.blogger.com/profile/02986381982136673388noreply@blogger.comtag:blogger.com,1999:blog-5699949251277141058.post-28641414114977884252020-01-29T22:59:57.808-06:002020-01-29T22:59:57.808-06:00Do you happen to have any research to back this up...Do you happen to have any research to back this up? I totally agree with this post. I have presented this information before to my learning coach at school and she did not agree with me. I am seeking some kind of research to back this up.

I might use this method of building numbers before introducing the Base 10 equipment as a 'ready made' version of what the children have been building in previous lessons.Annie Elinorhttps://www.blogger.com/profile/08741470506328470439noreply@blogger.comtag:blogger.com,1999:blog-5699949251277141058.post-33107585444883989762019-03-18T20:35:02.396-05:002019-03-18T20:35:02.396-05:00I totally agree with your thinking here! It is so ...I totally agree with your thinking here! It is so important for kids to build and decompose those tens themselves. I love what you are doing and know your kids will do wonderfully when it’s time for regrouping. I do think the base ten blocks have their place in math instruction though, just not necessarily in 1st grade. Let me explain. Higher place values (hundreds, thousands, ten thousands, etc.) still need to be introduced and practiced using concrete tools. While it is possible to build hundreds and maybe even thousands using pop cubes, the higher you go the less efficient this becomes. Students need an efficient way to model operations in the hundreds and thousands. His is where the base ten blocks are useful. Base ten blocks can even be used to model multi-digit multiplication problems. All of this is much more effective, however, if the students have first been taught to understand ones and tens the way you teach them.

When teaching 2nd graders addition and subtraction with regrouping, trading back and forth between rods and cubes is another step that they really don't have room for in their working memory. I like to use beans and then ketchup cups for grouping 10. When we get to 3-digit numbers we put 10 small ketchup cups into a bigger cup for 100.Anonymoushttps://www.blogger.com/profile/08056361423356013658noreply@blogger.comtag:blogger.com,1999:blog-5699949251277141058.post-47515436371763836902015-03-17T22:46:28.018-05:002015-03-17T22:46:28.018-05:00In plastic tubs.

Warning: the pic was taken before I got rid of my base 10 blocks, so you will see the tub on the shelf!:)Whitneyhttps://www.blogger.com/profile/02986381982136673388noreply@blogger.comtag:blogger.com,1999:blog-5699949251277141058.post-4332376514151315562015-03-17T22:36:25.557-05:002015-03-17T22:36:25.557-05:00Love this!
