Maurici Carbo
Obblog 2 is an elementary logic simulator that displays
15 basic logic gates and their truth tables. It shows
the possible inner workings of the logic gates. The user
can build elementary logic machines that function. Use
the "guide" link to view a list of videos as
support material.

***FEATURED TOOL
Tool: MathScaled
http://mathforum.org/mathtools/tool/198847/
CAST, Inc.
MathScaled is a prototype series of puzzles based on a
balance-scale format. The goal is to place different
shapes with unknown weights on the scale so that it is
balanced. Puzzles have embedded supports for solving,
such as a Scratch Pad for recording information and
the option for immediate feedback on your progress.
Learners can also choose from different levels of
puzzle challenge.

***FEATURED TOOL
Tool: MathSquared
http://mathforum.org/mathtools/tool/198848/
CAST, Inc.
MathSquared is a prototype series of grid-based puzzles
using basic math operations that help learners develop
logical thinking and reasoning strategies. Puzzles have
different levels of challenge and include embedded
supports for solving, such as a Scratch Pad for recording
information that supports problem solving and the option
for immediate feedback on your progress.
