Yep, that is just garter stitch and they will look the same on both sides. You're doing fine so keep practicing!
Now try combining the knits and purls into the same project. Like k5, p5, k5, p5 or whatever combination you choose.
Important - Each stitch has two sides. One side is a knit and one side is purl...therefore the back of a knit stitch is a purl and the back of a purl is a knit. When you rib you "knit the knits and purl the purls" as they face you. That means when the work is turned and in your left hand ready to start again. If it looks smooth like a V it's a knit so you knit it. If it's bumpy it's a purl so you purl it.
