the other responses seem to answer "what can i make from this?", but as a beginner you should ask "what can i learn from this?" . you could spall it up with percussion, and use the spalls to do some pressure flaking . then get lots more. each time you sit down to knap, aim to learn something and make some gravel- you'll never be disappointed. don't get attached to it, or agonise over what to do- just whack it . once you get the hang of it, making circles is a great way to learn- that is don't knap an arrowhead , just a circular biface. good luck!
