Modifying Ray's Arithmetic

I have for years now planned to use Ray’s Arithmetic when my dd was ready for formal math.  That time is now, and I’m finding as I look closely at both Ray’s New Primary Arithmetic (this links to a copy of the actual text) and Charlotte Mason’s math recommendations (page 253 at the link) that the two are not exactly in sync.  I prefer to follow CM’s recommendations, but I’m hoping I can modify Ray’s to fit so that I don’t have to create the whole shebang from scratch. 

I think we can follow this course for the first several lessons.  My lessons are numbered with Arabic numerals; Ray’s are numbered with Roman numerals.

Lesson 1 - Lesson XI – work out the table at the top with counters and drill over that, with counters

Lesson 2 – Lesson XI – drill on the word problems, orally

Lesson 3 – Lesson XI – drill on the word problems, orally, but phrase them as arithmetic problems (2+1 instead of using the word problem format)

Lessons 4-6 – Lesson XXV – repeat three steps above

Lessons 7-60 – Repeat this process for each of the next arithmetic lessons, alternating addition and subtraction lessons.  Optionally skip the last arithmetic lesson since it works with 10 and the implication from CM is that we would stop at 9.

Lesson 61 – Lesson XXXIX – work out the table at the top with counters and drill over that, with counters

Here I’m at a loss because I’m not sure if we should drill with word problems, as above, or continue straight to addition.  Any thoughts are welcome.

  1. I'm coming YEARS late to this conversation! I got Ray's Arithmetic 20 some years ago and have used the lessons with the counters with our children and then we did some drill. I never used it as a complete curriculum but as a supplement. We would use it before starting a math program and then to take a break from our math program.

    I love how the counter lessons explain counting, addition, subtraction, multiplication and division. Even 5 and 6 years olds can understand it. I have pulled it out for each of the children early on and sometimes I've used it again later for some reinforcement. They are fun, relaxed lessons that they have all enjoyed.
