A fresh example from Precalculus:

Quote
Core:
Read pp. 45–48, then complete the Core assignment (pp. 49–51 #11–29 odd, 30–37 all).

Alternatively, for additional practice, complete the Enriched problems instead of the Core assignment.
Enriched:
pp. 49–51 #11–37 all

Right. For "enrichment" or "additional challenge" do twice as many of the EASIEST problems in the homework set.
