Hello, I'm doing Montessori at home with my son and want to purchase some wooden base ten materials. In an effort to be as frugal as possible, I'm hoping to get a basic set that won't break my bank account. What do you recommend for the minimum of each to get by in elementary mathematics. How many 1000 cubes? how many 100 squares? how many 10 rods? how many unit cubes?
