Can you swap the black knights with the white knights in the minimum number of moves?
Overlaying pentominoes can produce some effective patterns. Why not use LOGO to try out some of the ideas suggested here?
This article looks at knight's moves on a chess board and introduces you to the idea of vectors and vector addition.
Explore the two quadratic functions and find out how their graphs are related.
Patterns that repeat in a line are strangely interesting. How many types are there and how do you tell one type from another?
Arrow arithmetic, but with a twist.
Points off a rolling wheel make traces. What makes those traces have symmetry?
I took the graph y=4x+7 and performed four transformations. Can you find the order in which I could have carried out the transformations?
Make a footprint pattern using only reflections.
How can you use twizzles to multiply and divide?
Introduces the idea of a twizzle to represent number and asks how one can use this representation to add and subtract geometrically.
The first part of an investigation into how to represent numbers using geometric transformations that ultimately leads us to discover numbers not on the number line.
