Contest review plus sequencing games

Contest review

Today we went over the contest from November. It was tough! As usual, most people who took the contest nationally got 0, 1, or 2 of the 5 questions.

I won't list the problems here, because they are proprietary, but I'll categorise them.

The first was one of those rearrangement / calculation problems we talked about the first day. You can blast through it as it is, or you can rearrange it to make your calculations a little faster.

The second problem was a sequence puzzle where some clues are given and then you deduce the order of some objects. More on this below!

The third problem was to figure out a three digit number based on some clues about the digits, including divisibility.

The fourth involved calculating the area of a shape surrounding some other shapes.

The fifth was a cryptarithm. You can find plenty of examples of those at http://www.cryptarithms.com

We'll do more of all of those throughout the year.

Sequencing logic puzzles

This kind of puzzle is really fun. There are lots of these on the LSAT — the standardised test for getting into law school. To practise these, I got some related puzzled from the Mindware game LogicLinks. They have samples from the four leveled books:

We worked through these until we ran out of time!
