Karen, where do you find your math manipulatives? I don't really have anything like that, and I hear so many people using these types of things. Also, measuring equipment....are you talking tape measure and ruler or are there other types of things out there
Teacher supply stores, homeschool catalogues or ebay are good places to find math manipulatives, and most homeschool school conferences will have vendors selling them. You can also order them online from places like
eta/cuisenaire. Things like pentominoes and tangrams are easily made with light cardboard. Just google for a pattern. You can also make geoboards with wood and nails - a fun project but I'm lazy and bought ours. Some "good" toy stores may also carry some of these things.
Measuring devices - I just hit the dollar (or thrift) store for rulers, measuring tapes (both the flexible sewing kind and the woodworking kind), measuring cups and spoons, thermometres (indoor/outdoor/candy/meat) - that kind of thing.
games - tell me about some more of your games....this is what we don't have a lot of, and we LOVE to play them!!
Lol - the list is long - this is what I can see on the game shelf and there are more in the basement.

a lot of general trivia games. We also have lots of puzzles, historical ravensburger ones where you have to spot the things on the edge of the puzzles, lots of geography/map ones and a few science specific (ie bugs, space, human body - most of these are Melissa and Doug puzzles)
some of your favorite activity books too....we only have 1 or 2 of these, and they really help me!!
Math:
Family Math,
Math Wizardry
a series from our library by Marion Smoothey called Let's Investigate - love these but they are slightly older kids and they are unfortunately OOP
You should definitely check out livingmath.net for other great math suggestions
For language:
books by Peggy Kaye
WordPlay by Lori Goodman and Lora Myers is good.
Wordplay cafe
some thrift store books like Wacky Words
madlibs
For science:
I have a few science ones that I like that I got at a thrift store - one is 365 Simple Science Experiments and another is called 101 Cool Science Experiments, and the last is Science Wizardry for Kids. Anything by Janice Van Cleave or Vicki Cobb is good. I wait for these to fall in my lap at the thrift store or used book store and I don't pay much for them. For older kids I really like the series How Math/Science/Earth/Weather Works and I actively pursue these

For History
For history I like the ones by Linda Honan...spend the day in Ancient Egypt/Greece/Rome. I have the SOTW activity books 1 and 2 and I'll use them as guides for possible activities and reading suggestions.
Art
I like Mary Ann Kohl - the great artists one is my favourite
We also get the Usborne Art Ideas books out of the library pretty regularly just for some project ideas
It looks like a lot when I write it out. I haunt thrift stores and used book stores, I stash garage sale finds and I give VERY specific lists to grandparents for Christmas/birthdays - I usually offer to buy the stuff and give it to them to wrap. I buy my aristoplay games used on ebay as they come up because many/most of them are out of production or incredibly expensive in Canada.
I really like Rebecca Rupp's Complete Home Learning Sourcebook for ideas of resources when my kids get "into" things.
HTH
