The first is a continuation of the decoding work we did last week. This one is a long division problem with missing digits. I think this should flow fairly easily from the strategies everyone was employing.
The second is from a new site I found and explores some more of the pentagon/pentagram geometry. The full question is a bit hard for the knowledge level we have but the more basic question: find the sum of the acute angles in a regular pentagram is really good practice.
