A Happy Medium

So I'm deciding on buying curriculum. So far I've decided on:

Science: Child's Play Science $4.75
Earlybird Start-Up Science $3.75

Math: Earlybird Kindergarten Math Standards Edition Textbook, $21.25; Activity book, $13.50; Readers, $32.50

English: First Language Lessons for the Well-Trained Mind $14.95
Handwriting Without Tears Kindergarten Teacher's Guide, $7.50; Workbook, $7.50
Handwriting Without Tears First Grade Teacher's Guide, $7.50; Workbook, $7.50
Ordinary Parent's Guide to Teaching Reading $24.75
Five in a Row
Explode the Code

History/Geography: Story of the World Text, $13.25; Audiobooks, $30.95; Activity book, $27.25; Tests, $10.25

Logic: Stepping Stones Text, $7.95; Teacher's Guide, $2.95

Foreign Language: Rosetta Stone German
Rosetta Stone Spanish

Art: Art Lessons at Home $23.75

I don't have the money to buy all of this at once so I'm going to split it up and buy one or two programs per paycheck.

I was going to get the cheaper version of Singapore math (the price was actually what drew me to it in the first place) but when looking it up right now I saw that they have a standards version which I'd imagine goes into more depth. So I'm going to buy that one. Though I am wavering between Singapore and Horizons.

Thinking about buying Edu Track for planning purposes.
