Expressing "At Least"

There are a few ways to express the concept of "at least" in Japanese. First, you can follow a number + counter word pattern (or a quantity word like 少し) with は, which will provide the "at least" meaning. You can also add だけは, ぐらいは, or くらいは after a noun to give the same meaning.
