Both saxon and singapore are good choices. Just wanted to point out that anything can be dry and repetitive, it will depend on how you present it to your child. And just cause a texbook has review ?s it in does not mean you have to do them. If your dc has demonstrated the knowledge of that particular skill, you can SKIP the review bit and move on along. Saxon is excellent because it does a great job of preparing children for upper level math where certain things must be commited to memory to move ahead.
Some kids need lots of review to really get what they need memorised as well as learning to think in a math minded critical how/why way behind the numbers.
I personally think math u see is way too expensive for what it is, mignon is not teacher friendly time wise to use and is slow paced & uses those cusinese rods that some kids really hate, gander has on cloud nine now and that is those unifix cubes, saxon is excellent but you need to be there with your dc to help them & be enthused that this is great, if you have an anti textbook bias or not sure mindset going into it, your dc will pick up on that.
Workbooks like singpores also need a parent sitting there explaining what the book asks for on review pages even after the child has learned the concept.
I use singapore cause it is cheaper then saxon and it is okay NOT great, has some flaws and we do a lot of guessing and skipping stuff with that. Singapore has two workbooks in one year with a textbook/workbook to fill in also & teachers key.
and that IMHO is too much busy on paper work
We just use the two workbooks and I sell the other stuff on the 'bay' We have used mortenson math also in the past and loved that but had a hard time finding it to buy.http://www.mortensenmathdirect.com/
You can hit a teachers supply for the base ten blocks IMHO better choice then any of the other manipulatives
or buy them herehttp://www.michaelolaf.com/1CW612math.html
and play lots of board games, yahtzee to drill addition facts easily
and use montessori homemade things to supplement,http://www.montessorimaterials.org/math.htm
or the free stuff online like activities from aimshttp://www.aimsedu.org/Activities/samples.html
i like the cdrom rainbow math the sonlight sells and the quartermile to use for review instead of the saxon type drill in the texts.http://www.thequartermile.com/http://www.lexialearning.com/product_xtrn.htm
for visual spatial to teach thinking skills VIP we use their reading software also and it is excellent
There is hooked on math now from the H o phonics folks that I have heard both good and horrible things about.
I have MCP for one ds and will move into that after my ds#3 is done with this years singapore and we give a thumbs up to the videotext algebra series and jacobs geometry for older kids which prepared my oldest for his college algebra well.
I suggest figureing out how much time you want to spend, how much money you want to spend and how your dc learns best before buying anything and ask on the trade board if anyone has a workbook or text from the series you are most intersted in they are not using to check it out before buying the whole shebang. .
I suggest ~ Get a rainbow resources catalog and read their reviews of each math curriculum they sell. They are fair ones.http://www.rainbowresource.com/index.php
sorry so long, it is late and I am trying to hurry before getting to bed
