Tangrams

The tangram is a puzzle consisting of seven flat shapes, called tans, which are put together to form shapes. The objective of the puzzle is to form a specific shape (given only an outline or silhouette) using all seven pieces, which may not overlap. It is one of the most popular puzzles in the world. Tangrams are an excellent way to increase mental and visual skills. Using imagination, geometrical shapes, letters, numbers, figures, boats, animals and objects can bring great fun along with a challenge.

Swish!

Swish is a spatial card game that challenges you to be the first to make matches, or “Swishes.” Swishes are made by stacking as few as two or as many as 12 cards so that every ball swishes into a hoop of the same color. The player with the most matches at the end of the game wins. Let’s have some ThinkFun!

Top Secret

You have been working diligently on breaking codes with numbers and colors.  Now it is time for letters and symbols.

Codes have been around for a very long time. Throughout history, world events have changed because of secret messages. Sometimes, however, it is important that only a few people understand the message. In the world of cryptology, codes are used to make messages secret by changing the words into something else. In order for your friends to understand the coded message, they need the key!

Next, you will learn about different codes, how to make codes, and what to look for when trying to break a code. Let’s start with the Polyalphabetic Substitution Ciphers.

Breaking Codes

Last week we played the logic game, Pico Fermi, Bagel. This week we will continue breaking the code using four digits or colors. The game, Mastermind, uses four colors. Here is how to play:

Play and practice online – MASTERMIND.

Pico, Fermi, Bagel

Today we will look at the logic that underlies the game “Pico, Fermi, Bagel”.

How to Play:
The the game begins with one person secretly choosing a number with no repeated digits. We will start with a three digit number. Then others attempt to guess the number, and the one who chose the number responds to each guess as follows:

  • If the guess has no numbers correct, they respond: “Bagel.”
  • For each digit when the guess is correct but in the wrong place, respond: “Pico.”
  • For each digit when the guess is correct and in the correct place, respond: “Fermi.”
  • When all three digits are correct and in the correct place, respond: “CREAM CHEESE.”

We will play a few rounds of the game together, and then try to solve a couple problems related to the game.
