We are currently using Real Science 4 Kids (the pre-level in each subject). It does fit us & we like it, but I need either a new curriculum or a supplement. It does not cover the areas of measurement (volume, mass, etc), animals (habitat, mammals/reptiles/fish/etc., food, etc.), weather, etc.
I am looking for either (secular) unit studies I can buy to supplement in these areas, or I need a better (secular, more comprehensive) curriculum. Please advise :)!
I considering McRuffy Science, has anyone used this? Would you say yay or nay?
