This activity is based on the documented lies told by the Former President of the United States (FoPUS), Donald Trump. Donald Trump is unique in that all his lies were counted and documented by various news outlets, including The Washington Post. This has inspired me to develop an activity to investigate mathematics. In this case, it is the milestone that Trump reached on January 10, 2018, when Trump told his 2,000th lie, as documented by The Washington Post. Update: The Washington Post now re

56 puzzle challenges where kids use combinations of numbers vertically, horizontally or diagonally to make 56using any of the 4 operations in any combination. Mucho fun!

This is a fifth and final set of 13 3-D spatial problem solving puzzles that provide a maximum and ultimate challenge for solvers. There are three different kinds of puzzles: Basic Puzzles: These are puzzles which show the solution to the puzzle in three different colors. Students have to locate the proper pieces and assemble them as shown in the diagram. Intermediate Puzzles: These are puzzles where the solver is told which 2 - 3 pieces to use, but not how they fit together. Students locate t

This is a fourth set of 10 3-D spatial problem solving puzzles that use 3 - 4 of the seven Soma pieces. There are three different kinds of puzzles: Basic Puzzles: These are puzzles which show the solution to the puzzle in three different colors. Students have to locate the proper pieces and assemble them as shown in the diagram.

Note: You can get this material for free if you purchase Set of 10 Wooden Soma Cubes This is the first of a set of increasingly difficult challenges which are based on the 7 piece Soma cube. The Soma cube, if you aren't familiar with it, is a 3 x 3 cube dissected into 7 different pieces. It makes an excellent platform for inspiring your students to do 3-Dimensional spatial problem solving. This is the first collection that is based on "2 piece" puzzles. There are three different levels of cha

4 Magic Square Puzzlers for EVerYOnE!

You've heard of geometry, right? You know all about tessellations, correct? You know about fractals, uh-huh. And you know about puzzles? Sho' 'nuff! This is a set of hands-on puzzle activities that combine all three. Rep-Tiles, aka "repeating tiles," are a special kind of tessellation known as a "fractal" where the pieces can be assembled to make dilated duplicates (that's larger versions) of the original tile. Now you can already do this with squares and equilateral triangles, which are known

Greetings phrens: this is a 41 page guide to how to think about the basic measures of central tendency in statistics (mean, median, mode and range) beyond the basic recitation of "here's how to do it." If you think about it, statistics is one of the most important and relevant area of mathematics that we teach. It is powerful because it allows us to take large amounts of data and and distilling it down into just a few numbers. However, very often these numbers are either irrelevant, non-repres

Okay, so there's new movie and it's got something about tesseracts in it, and the book was by Madeleine L'Engle, then this is what you've been looking for! This is the only set of plans on TeachersPayTeachers for a four dimensional cube, better known as a "hypercube" or "tesseract." Includes easy to cut out plans for the following: • blank hollow hypercube • hypercube with printed graphics, including the various names and properties of a hypercube. • a "filled" hypercube which has a cube

I know this is growing out of control, and lucky for you, I kept the price at $9.95; consider this a bargain! • Recently added: Why you should NOT make your students draw fractions (they'll stink at it no matter how hard they try), and an excellent alternative to drawing cruddy pies, wobbly bars and squishy squares.... • Complex Fractions: every heard of them? Show this to your kids and they'll develop new strategies for comparing fractions and finding new ones. * I explain why you should never
