Download and print the pattern. Choose a design that prints in color, or select one of the black and white patterns and use your creativity to add color and designs. It is easiest to fold patterns that have numbers or counting dots. Fun Maths. Teachers!

Fun Maths

Here is a collection of mathematical activities containing an element of 'fun'! Some activities will be perfect for the last ten minutes of a gruelling double period while others could be saved for the last lesson of term. Purposeful Practice & Dandy Candies – dy/dan. Practice may not always be fun, but it can be purposeful.

Purposeful Practice & Dandy Candies – dy/dan

Some of my favorite tasks lately contain purposeful practice. For instance, Dandy Candies tells students they’re going to package up 24 cubical candy boxes. It asks them, “Which of four packages uses the least amount of packaging? Which uses the least amount of ribbon?” 6.G.1 – Yummy Math. Two activities to help celebrate National Donut Day How many donuts is that = huge box of donuts to approximate.

Laboratorio. Carta a punti isometrica. Free Online Graph Paper / Asymmetric and Specialty Grid Paper PDFs. Billiards and Puzzles. Puzzle #1: Consider a rectangular billiard table with 4 pockets, as shown in the figure.

Billiards and Puzzles

One has to put four black balls into four different pockets one at a time, by hitting the white ball. As usual, the balls must bounce from the border with mirror symmetry as we have seen so far. When the white ball hits a black ball, it replaces that black ball's location, and the black ball continues the natural motion. In this process, black balls must never hit each other. This puzzle was used in the PQSRT puzzle competition, Reference #3.

The solution is rather simple. Arithmetic billiards - Wikiwand. Geometrical GCD and LCM algorithm The arithmetic billiard for the numbers 15 and 40: the greatest common divisor is 5, the least common multiple is 120.

Arithmetic billiards - Wikiwand

In recreational mathematics, arithmetic billiards provide a geometrical method to determine the least common multiple and the greatest common divisor of two natural numbers by making use of reflections inside a rectangle whose sides are the two given numbers.

Arrange the colored shapes so that they completely cover the large white square. When finished, click the Fit Shapes to Square button. Shape Tool. Biliardo aritmetico.

Mathematical billiards is an idealisation of what we experience on a regular pool table. In mathematical billiards the ball bounces around according to the same rules as in ordinary billiards, but it has no mass, which means there is no friction. There also aren't any pockets that can swallow the ball. This means that the ball will bounce infinitely many times on the sides of the billiard table and keep going forever. One fascinating aspect of mathematical billiards is that it gives us a geometrical method to determine the least common multiple and the greatest common divisor of two natural numbers.

Have a look at the Geogebra animation below (the play button is in the bottom left corner) and try to figure out how the construction works. The basics Here is the basic idea. And. Spieglein, Spieglein an der Wand. From Wolfram MathWorld. The game of billiards is played on a rectangular table (known as a billiard table) upon which balls are placed. Vai all'angolo!
