Were you stressed or frustrated? How did you deal with that emotion? Talk about how you felt during this activity.That’s the only way to solve the infamous nine-dot problem! Do not worry about extending the lines “outside the box” of the three rows of three dots. This adjustment in thinking can help children think about how lines can cross at angles other than 0, 45 and 90 degrees. It is important to observe how these dots are not dots per se, but rather are round discs or filled-in circles. A solution may not be found right away.Try to connect all of the dots using four lines or fewer without lifting the pen.Make the dots about 1/4-inch in diameter, or about the size of a pea. Use the template below or draw a square grid of nine dots, with three rows of three dots spaced evenly apart. The nine dots puzzle is a mathematical puzzle whose task is to connect nine squarely arranged points with a pen by four (or less) straight lines without.This activity literally requires thinking outside of the box in order to solve it. that all we have to do is tell people they can go outside the box and they will find it easy to solve the problem.Try to connect nine equally spaced dots using four lines or fewer without lifting a pen! The trouble with the usual way of presenting the nine-dot problem is that it contains (ahem) an unexamined assumption. What’s the problem with the Nine-Dot Problem? Use a pencil to draw four continuous straight line segments which go through the middle of all 9 dots without taking the pencil off the flat surface of the paper. (iv) Two dots can be connected by only one line. (iii) All 4 lines are endless so you can stretch out beyond the 9 dots. Solution Start at A go to B then C then D then E You need to draw line segments that go beyond the dots to solve the problem A B D C E The 9 dot puzzle is an old puzzle. (ii) You cannot overlap lines or retrace any line. The Nine Dot Puzzle Use a pencil to draw four continuous straight line segments which go through the middle of all 9 dots without taking the pencil off the paper. Don’t read any further until you’ve tried to solve the problem. you must not lift your pen from the paper once you start drawing. The straight lines must be continuous – i.e. To solve the problem, you need to join all nine dots by drawing no more than four straight lines. Get a pen and some paper and copy the nine dots arranged in a square below. The solution involves looking outside the two-dimensional sheet of paper on which the nine dots are drawn and coning the paper three-dimensionally aligning the dots along a spiral, thus a single line can be drawn connecting all nine dots – which would appear as three lines in parallel on the paper, when flattened out. The problem is that unless you do consider going outside that box, you'll never. Connect the 9 dots using four straight lines without lifting the pencil from the paper. Join 9 dots with 4 straight lines without lifting the pendots puzzle. What is the solution to the nine-dot problem? Connect and share knowledge within a single location that is structured and easy to search. Most users use only 5 nodes, and a significant amount only used 4.77% of users started their patterns in one of the corners.44% of people usually start their patterns from the top-left corner dot. Starting from the top left corner, go diagonal to the bottom right corner, turn left and go to the bottom left corner, from there go outside far enough to cut diagonal through the two top left corner dots, and then down the three dots on the right side.Here are some of the most common lock pattern habits Participants are presented with a set of dots arranged in a 3×3 grid and challenged to connect all nine dots, without lifting their pencil from the paper, using the fewest possible number of straight lines.
So have another go at solving the problem, allowing yourself to draw outside the box. It is possible, honest! Solution – but don’t click here until you’ve tried it for yourself. Can you connect all the dots with 4 lines?Īs long as you don’t change direction, it will all count as a single line.
