Liar’s Math

Pinocchio lies

When Pinocchio lies, his nose gets twice as long. When he tells the truth, his nose gets 1 cm shorter.

Today, his nose was 1 cm long in the morning, and it is 100 cm long in the evening.

What is the least possible number of times he opened his mouth today?

True and Random

Two gods  are called True and Random. True always speaks truly and Random speaks randomly truly or falsely. You don’t know who is who.

Determine the identities of the gods by asking yes-no questions; each question must be put to exactly one god.

Adapted from G. Boolos. ‘The hardest logic puzzle ever’, The Harvard Review of Philosophy (6), 1996.

Mathematical Intelligence

WHAT IS IT?

Mathematical reasoning is an essential part of literacy.

Literacy is “an individual’s ability to read, write and speak in English, and compute and solve problems at levels of proficiency necessary to function on the job and in society to achieve one’s goals, and develop one’s knowledge and potential.”  – American National Literacy Act of 1991

HOW TO GET IT?

Mary Matthews of Blitz Games Studio, UK says ” Exploration, experimentation, team building, problem-solving and independent, personalized, differentiated experiences [will tap into] the full potential games can offer for learning.”
