4434Proof Designer
https://www.merlot.org/merlot/viewMaterial.htm?id=78631
Proof designer is a tool intended to help students who are beginning to learn how to write proofs. While proving theorems certainly is a creative task, there are many steps that actually are schematic and mathematicians have internalized them. For example, to prove a universally quantified statement we need to pick an arbitrary element and prove the statement for it. These types of nestings are not automatically done by novices and they take time to internalize. In proof designer such steps are created upon selection with the characteristic start (״Let a be ") and the characteristic ending (״Since a was arbitrary "). The user still has to fill in the steps in between. In the above fashion proof designer can be used to keep track of and demonstrate the macroscopic structure of the proof as well as the nesting of sub-proofs within a proof.Mon, 10 Feb 2003 00:00:00 -0800Truth Table Constructor
https://www.merlot.org/merlot/viewMaterial.htm?id=82130
Truth Table Constructor creates truth tables for statements in propositional logic. It allows entry of up to six variables and six connectives and produces T/F and 0/1 output. Results are shown all at once or may be requested step-by-step.Sat, 2 Oct 2004 00:00:00 -0700Interaktive Logik (Gateway to Logic) (CG1-1)

https://www.merlot.org/merlot/viewMaterial.htm?id=1113860
This suite of 6 games covers elementary math skills from addition & subtraction to multiplication & division, to fractions and decimals. My students’ current favorite is Motion Math Pizza, where they build and sell pizzas to hungry customers, setting the prices and seeing how basic economic principles work.Tue, 29 Dec 2015 15:20:15 -0800obblog
