Is Singapore math really cheaper than CTC's Math Reasoning?

[pwicks]

So I came across a few posts which mentioned that Singapore math is cheaper than Critical Thinking company's Math reasoning. Is my math wrong? But it seems the opposite:

 

So for Singapore Math- Primary math US edition there are 2 Textbooks and two workbooks per level thats 4 books at $11.80 each on their website Plus $18.50 (2/level) for the home instructors guide. That is ~$84 per level.

 

Critical Thinking Company's Math reasoning is currently on sale for $35-$38 for one level.

 

Am I missing something?

 

I read one post where Math reasoning was referred to as Singapore math on steroids...  that sounds like MR is good.

 

I am looking for something to supplement my public school kids (DS is in K and DD is in 1st) they have pretty much absorbed any math I put in front of them (Mathseeds, Dreambox, various workbooks including Kumon) and I'd like to keep them engaged in math.

I think CTC Mathematical Reasoning is cheaper because you buy only one book, whereas with Singapore Math you buy the textbook and workbook, part A and part B plus if the teacher's guide if you want that.  It was someone I met who sells CTC and is a longtime homeschooler who referred to Math Reasoning as Singapore on steroids.  I like both MR and Singapore. 

 

As an afterschooler though, I am having trouble working through all of the books in a timely manner.  So I am thinking for next summer, I am just going to buy some Math Mammoth topic books.  I love Math Mammoth, love the way Maria teaches math.  I only switched to Singapore because I was teaching one child at home last year and trying to find a curriculum that aligned closely with his K12 math.  That ended up being Singapore Standards edition.  Then I heard a talk by the above lady who sells CTC and couldn't resist trying CTC Math Reasoning.  It's a spiral curriculum. 

 

But I think we will go back to Math Mammoth next summer for topic workbooks so we can finish them in the summer and not having this huge workbook hanging over our heads.  I find a complete math curriculum to be useful for my younger children, say K-2, but a little too much for my older ones.
