A homeschooler's website and ideas for getting children excited about math. Includes a wonderful math history program. Tons of living books recommendations!
Miquon Math from Key Curriculum Press. I believe it is meant to be used through 4th grade although my kids have usually transitioned to Singapore Math by then.
I really like this curriculum for getting kids started in math. It is quite different from most math programs and when the kids are in K -2nd grade I alternate it with "math play" and a wider variety of math manipulatives. Miquon really helps wire the young brain for concepts they will need to be comfortable with for higher level math in middle school. You must have the Lab Sheet Annotations book and a set of cuisinaire rods in order to use Miquon effectively.
Math for Fun Projects by Andrew King, Copper Beech Books, 1999.
A decent resource for adding a hands-on/nonworkbook component to your math. Best for grammar stage. This book can be found as part of a series as well as in one giant book containing the full series.
How Math Works: 100 Ways Parents & Kids Can Share the Wonder of Mathematics by Carol Vorderman, Reader's Digest, 1996.
An excellent resource to supplement any math program. Part of the wonderful How...Works series recommended in Well Trained Mind as well as Living Math . The activities sort of add a "lab" component to balance a traditional math education.
