Let's represent the number of packages Sam originally bought as "x".
Since each package has 9 beads, the total number of beads from the packages he bought is 9x.
His mom bought him 63 more beads, so the total number of beads is now 9x + 63.
We know that the total number of beads he has now is 153, so we can set up the equation 9x + 63 = 153.
Subtracting 63 from both sides of the equation, we get 9x = 90.
Finally, dividing both sides by 9, we find that x = 10.
Sam originally bought 10 packages. Answer: \boxed{10}.
Sam is buying packages with 9 beads each. His mom bought him 63 more beads. Now, he has 153 beads.
