    I am reviewing the material we’ll be covering for grade 1 Ray’s (and comparing it to another program) and I’m not seeing a lesson on place value.  I looked at the scope/sequence as well as each lesson.  Am I missing something?  Do we need to teach this similar to what I’ve seen in other programs (houses, streets, dimes & pennies, etc).  If I overlooked it please tell me what lesson or page it’s on.  Thanks.

    Place value was not a thing that used to be taught. It was a thing you worked with – you learned to carry the one, but the “ones place”, the “tens place”, those terms were not used. If you feel you need to teach this – and really, the only time my kids have honestly needed it was for rounding to the ____ place- you will have to add it.

    Ray’s is old style math. The new math now teaches all sorts of things that never used to be named, but were just used.

    If you want to teach it I would use money or a bundle of sticks. Mathematics An Instrument for Living Teaching by Richele Baburina as sold on this site is very helpful. She has a scope and sequence as well as quotes from Charlotte Mason and peers on the subject and examples of how to implement varous lessons. The ebook is affordable. Well worth every penny you spend on ether ebook or hard copy if you are truly interested in using Charlotte Mason’s methods of educating your children. Richelle is also extremely helpful and can be reached by pm if she doesn’t happen to see this post. I am no scholar on the subject but can tell you that in teaching place value you should use money, bunndles of stick, etc. instead of houses on the street. Get the book… you won’t be sorry. 🙂

    Yes, I have that book and agree that it’s wonderful. It referenced the bundles so I thought it’s something that needed to be “taught”….along with it being mentioned in every other curric.! DawnD mentions that I shouldn’t really need it but I was wondering if anyone else using Ray’s is teaching it. If yes, what lesson number would be appropriate?

    I plan to use Ray’s but do not have it yet.. I’m so excited to have found a used set that is all hardback at an affordable price. I hope someone answers who is knowledgable and can offer more help but if not I was thinking that it would fit in just as you were teaching two digit addition.

    Hi Leslie,

    We know that ideas are paramount in a Charlotte Mason education and that her methods in teaching every subject embrace this principle, arithmetic included.  You are right – conveying the idea of place value is important. 

    If you are using Ray’s New Primary Arithmetic, once you have reached lesson XX, have your child work out the sums in that lesson. If you’ve passed this lesson, please don’t worry as you can present the idea of place value anytime after your child has investigated the number 10. Now it is time for mother to reacquaint herself with Charlotte’s methods found in pages 26-29 of the SCM handbook – being sure to read through point 27.

    You will use points 15., 16., 19., 20., and 21. for subsequent lessons before continuing on with 11-20. These will be mostly hands-on lessons — as Jessica said, manipulatives found in your own home are one of the tools used to present this idea — bundling of craft sticks or wooden kitchen matches, stringing of beads or buttons into ten bundles. The writing of number 10 (see the image in the handbook that goes along with point 16) as well as having your child place pennies to the right and dimes to the left when working with coins also helps present the idea of place value.

     

    When your child gets to the point in Ray’s of carrying in either addition or multiplication, have him/her say they are carrying “two tens” rather than “two,” etc. You’ll find this laid out for the older student in the sections on “Notation” and “Addition” of Ray’s New Practical Arithmetic. As Dawn said, it is a principle used and not just named. 

    In hopes that this has helped…

    Kindly,

    Richele

    Thank you, Richele. I’ll have to trust the Lord on this one as it makes me nervous. I feel like I have no clue with teaching math and I add such importance to it…I know I shouldn’t.
