Math Fan Content Lessons Tasks Math Club Projects Math @ Home Math Magic Games & Puzzles Math & Art < < MATH & ART Spirographs As we all know, through play, kids learn different things without even realizing it. Playing with a spirograph, experimenting, and trying all kinds of combinations, kids will develop mathematical and scientific intuition they can draw and realize the patterns. With the proper questions, they can experiment, hypothesize, test, and generalize even reach conclusions. A Spirograph is a geometric drawing device that produces various mathematical curves such as hypotrochoids and epitrochoids. The well-known toy version was developed by British engineer Denys Fisher and was first sold in 1965. Visit the original toy’s website. There is also a very successful online version here. ​ The patterns that are created depend on three variables: the radius of the fixed disc or wheel (the number of teeth) the radius of the revolving disc (the number of teeth) the location of the point on the moving disc. ​ By changing any one of these variables, you can get tons of incredible and beautiful patterns. Please check Wolfram's collection of plane curves to identify them. A point on a wheel rolling inside a circle traces out a hypocycloid. A point on a wheel rolling on a flat surface traces out a curve called a cycloid. A point on a wheel rolling outside another wheel traces out an epicycloid. A spirograph can also be used to study; LCM Modular arithmetic The fundamental theorem of mathematics.

He was a mathematician, physicist, astronomer, engineer, inventor, and weapon-designer. As we’ll see, he was a man who was both of his time and far ahead of his time. Archimedes was born in the Greek city-state of Syracuse on the island of Sicily in approximately 287 BCE. He directly inspired Galileo Galilei and Isaac Newton to investigate the mathematics of motion. Archimedes’ surviving works (tragically, many have been lost) finally made it into print in 1544. Leonardo da Vinci was lucky enough to see some of the hand-copied works of Archimedes before they were eventually printed. ​ Calculating Pi like Archimedes Archimedes Infograph Project Archimedes

Math Magic and Illusions 1. The Famous Mystery Calculator Trick Ask your friend to choose a number [1-63]. Show them each card here in turn and ask them if their number appears on it. You can guess the number by adding the top left corner numbers of each card that has their number. Can you find the trick? The first hint is if you have one more card, your friend can pick a number [1 - 127] Can you guess it now? Another hint is 1 appears only on the first of the cards and 63 appears on them all. ... Yes, It is the Binary way of writing the number - each card is the binary digit represented by the top left corner number. (Cards are not in exact order to create the mystery!) 63 = (1 + 4 + 16 + 2 + 8 + 32) 1 1 1 1 1 1 (in all 6 cards) 23 = (1 + 4 +16 + 2) so only in first four cards. 2.

Fun Mathfan Content Lessons Tasks Math Club Projects Math @ Home Math @ Home Games & Puzzles Math Magic Math & Art Everyday Math Day 1: Roman Arch Bridges Grab all the cushions, books or Jenga blocks at home and try to build an arch bridge. The forces of a Roman arch so strong that arches can stand without any glue or other adhesive holding them together. Try it for yourself! ​ How it works: Its semicircular structure elegantly distributes compression through its entire form and diverts weight onto its two legs, the components of the bridge that directly take on pressure. Roman Bridge, Ponte da Vila Formosa, Portugal Blueprint of the Arch Bridge Home Made Arch Bridge Roman Bridge, Ponte da Vila Formosa, Portugal 1/3 Image attributions: https://www.ancient.eu/image/4407/roman-bridge-ponte-da-vila-formosa-portugal/ https://www.thisiscarpentry.com/2012/01/06/circular-based-arches-part-1/ https://www.thelistlab.net/blog/how-to-make-a-book-arch ​ Resources: https://kids.nationalgeographic.com/explore/books/make-this/roman-ice-arch/ Day 2: Leonardo Da Vinci’s Famous Self-Supporting Bridge Do you have popsicles at home? I did not try with toothpicks or q-tips, but I think that they may also work. Other than those, “Patience” will be the main thing you will need. Leonardo Da Vinci’s Self-Supporting Bridge is also known as the emergency bridge. No nails, screws, rope, glues, notches, or other fasteners are holding the bridge in place. ​ You can also watch the step by step instruction video but first I suggest you try by looking at the image below. ​ How it works: You will be weaving the sticks together so that the tension between the sticks keeps the bridge together and lifts it off of the ground. You may also watch the video on YouTube how a father and son build the bridge at their backyards to motivate yourself to keep going :) 1/4 Image Attributions: https://www.core77.com/posts/65043/Leonardo-da-Vincis-Ingenious-Design-for-a-Self-Supporting-Bridge Resources: https://thekidshouldseethis.com/post/how-to-make-leonardo-da-vincis-self-supporting-arch-bridge https://www.instructables.com/id/Da-Vinci-Popsicle-Stick-Bridge/ Day 3: Cylindrical Mirror and Anamorphic Art ​ The original is the usage of mirroring paper, but nowadays unwrinkled aluminum foil can be used as well (But because the images are fuzzier, the observations may not be as clear.) And a soda or coke can, or any cylindrical object that you can cover with the aluminum foil is ok. After you create the cylindrical mirror, you may either color an already distorted image (1) or print the polar grid (2) below and create your own anamorphic art. How it works: Making anamorphic drawings involves mechanically distorting an image by transferring the image from the square grid (the original image) onto a polar grid (distorted grid. It is a mapping, or a correspondence, between a cartesian set of coordinates, and a polar set of coordinates. ​ Place your cylindrical mirror on the circle and look into the mirror to see the image restored. ​ Resources: https://anamorphicart.wordpress.com/2010/04/21/cylindrical-mirror-anamorphoses/ https://raft.net/wp-content/uploads/2019/03/278-Anamorphic-Art.pdf https://makezine.com/projects/draw-distorted-pictures/ Coloring a Distorted Image (1) You may color the distorted image below from makezine.com, in that case, my sure that the cylindrical shape you will find at home matches the circle at. The center of the paper. Link for already distorted Makey Bot image : Polar Grid Template (2) You can also use this polar grid by printing to make your own drawings; ​ Link for the Polar Grid Day 4: Pi at home ​ You can do lots of different pi activities at home. I want to list a few very popular ones. Pi – skyline: All you need is paper, ruler and crayons, create black bars at the lengths of the digits of Pi and create the skyline for Pi-York, Pi-ris, Pi-lan, Pi-chester …. ​ Building Pi-City with Lego: Instead of coloring the digits of Pi, you can use the lego pieces to actually build your Pi-city ​ Pi – bracelet: If you have the toolkit, all you need is to give each color a number like; 1 -pink, 2-blue, 3-green, 4-red .. And you can start forming your pi bracelet. Pi Art in a Circle: Simply divide a circle into 10 equal intervals label them from 0 to 9 if possible each with different colors. Start drawing lines from 3 to 1, 1 to 4, 4 to 1 and go on … Use the same color for the segment with your starting point for each of the drawings … ​ Pi – Dart Game If You have Dart Board at home by throwing dart, you can calculate Pi. Here all you can do is watching this video. Before I forget, Pi number; 3.1415926535 8979323846 2643383279 5028841971 6939937510 5820974944 5923078164 0628620899 8628034825 3421170679 ... ​ Image Attributions and for more information please visit; https://www.whatdowedoallday.com/ http://www.pinkstripeysocks.com/2014/03/pi-day-activity-make-pi-day-bracelets.html Day 5: String Art Another paper, pencil and ruler only activity. But this is to create your art on the paper. If you want to create some 3d art, you can always use a corkboard, pins, and some string. Even if you have the necessary materials for 3d art, I recommend you start with paper and pencil first. ​ Draw a big “L” shape on a paper and mark the numbers with equal intervals till 15. Or you can use the templates below. Again, all you are gonna do is drawing straight lines with a ruler to connect the points such as the; The first point on y-axis goes to the last point on x-axis ​ The second point on y-axis goes to the second-last point on x-axis … Spoiler Alert: When you have finished you’ll see that you have created a curve by using straight lines. You can extend your initial drawing by converting your L shape to a “+” plus sign Then you can try a 60 angle “<” as your initial figure and complete it to a hexagon by connecting 6 of them from their corners. (Here you can use less number of points on the lines..) String art is a topic with no limits if you feel like you are interested, make sure you’ll make an internet search. ​ Have math fun... 1/9 Links for the String Art Templates: ​ L Shape + Shape Square Shape Octagon 60 degrees Hexagon 1 Hexagon 2 ​ Day 6: Vedic Worms Fill in the multiplication table grid and reduce double-digit numbers to a single digit by adding the digit of the products. ​ Example: If 9×9=81, add the numbers in the sum (8+1), and put the sum of 9 in the square. If the new sum is also double-digit, add those numbers. Example: 7×8=56; 5+6=11; 1+1=2. Place the number 2 in that square. ​ We are going to use this number sequences to create the Vedic Worms which are also spirolaterals Spirolaterals are geometrical figures formed by the repetition of a simple rule. The pattern is formed by drawing line segments of a certain length from a number sequence with a fixed angle and a direction. ​ Although the spirolaterals can be created with any number sequence, we will use the Vedic Squares we have created. That’s why they are also called “VEDIC WORMS”. Start with a row of numbers you choose. (1,2,3,4,5,6,7,8,9) These numbers will determine the length of each ‘step’ of the ‘spirolateral’. 2. Choose a direction; clockwise (CW) or counterclockwise (CCW) 3. Choose a grid type to draw on (In fact here, you are choosing the angle of your movement) Square Grid (90 degrees ) Isometric Grid (60 degrees ) ​Hexagonal Grid (120 degrees ) … 4. Now start drawing spirals through your list. For example, if we choose CW direction on a square grid with the first row of numbers, It means 1 step up, 2 steps right, 3 steps down and 4 steps left then repeat like 5 steps up, 6 steps right, 7 steps down and 8 steps left and 9 steps up to complete your drawing. Please check t he post about the Vedic Squares, Worms and The Spirolaterals for the necessary materials.. ​ Day 7: Two (Hinged) Mirrors and Shapes If you have two small mirrors at home, it means you are ready for this activity. ​ I had two hinged mirrors that I got from Amazon recently, but any mirrors like some of the foldable vanity mirrors or small Ikea ones will do. ​ In addition to the pair of mirrors, any shapes, tangram pieces, lego pieces, different shaped toys can be used for this activity. ​ 1. Angles, Reflection, Tessellation: ​ Tessellation is covering a surface with a shape(s) without any gaps or overlaps. You can create your tessellation by using lego pieces, shapes anything you can create your design. ​ Then, use the mirrors to enlarge your design: Arrange the mirrors as a straight line (180) to double your design! Arrange the mirrors with a 120-degree angle in between to triple your design! Arrange the mirrors with a 90-degree angle in between to ? your design! Arrange the mirrors with a 60-degree angle in between to ? your design! 2. Lego Pieces, Other Half, Polygons ​ Create a car, a space ship, a dragon whatever you like but only half of it, then use the mirror the create the other half. You can do the same by holding the mirrors with different angles to enlarge your designs. ​ Now use a thin, long lego piece, or any toy that you can use as a line segment. ​ Arrange your mirrors with a 120 degrees, put the lego piece in between, what is the name of the polygon you have created? Try the other angles (You can measure the angles with a protractor) what kind of polygons you can create? ​ What if you want to form a polygon with 12 sides (dodecagon), how are you going to arrange the mirrors? ​ You can repeat the same activity by drawing a line segment on a paper and putting the mirrors on it by creating different angles between them. 3. Fractions and Creativity ​ Let's try something else, if you have two identical triangles like tangram pieces ( if don't simply draw, color and cut two identical triangles from paper) arrange them in all the possible ways to create a square by using the mirrors? ​ Which angle you need to use to create the square? ​ How many different designs can you make? ​ What fraction of your design is purple? What about your initial shape? Are those fractions equal? How many different ways you can divide a square into halves? ​ If you want to create a snowflake with a shortcut, what would be the angles between your mirrors? ​ If you want to draw an octopus by drawing only one of its arms, then which angle you need to use? ​ ​ BY USING TWO MIRRORS, YOU CAN LEARN ABOUT; ​ ANGLES POLYGONS TESSELLATION SYMMETRY REFLECTION FRACTIONS .. ​
