Dear all,
Please do watch my first video on my YouTube channel “Making Mathematics Meaningful”.
Topic: “Counting the number of Squares & Rectangles in nxn array (Part 1)”
Non-Routine Mathematics
(a) using pattern observation
(b) using a formula-based approach
The video also explains the method to count the total number of squares and rectangles in mxn array

PROJECT WORK TOPICS FOR CLASS IX AND X

-
--> Dear All We are well aware that CBSE is acknowledging the concept of internal assessment in Mathematics for the past three years wherein a student studying in class IX and X is supposed to submit a project work in Mathematics. This project can be in the form of extended learning in the subject or related to real life situations as well. Click here to download the evaluation performa for the same. I have observed that students are usually confused while selecting the topic for their project work. That is why; I want to share a few possible topics to help them pick up a suitable topic which suits their aptitude and attitude (as separate posts). Students will have the liberty to take the decision of taking up individual or a group projects (though they need the consent of their concerned math's teacher!). I would also discuss (in brief) about each topic and share some related resources which may prove to be helpful. few suggested topics are: 1. day on given ...

Dear All, Pi Day is held to celebrate the mathematical constant Ο€ (pi). Pi Day is observed on March 14 (3/14) , due to Ο€ being approximately equal to 3.14. Pi Minute is also sometimes celebrated on March 14 at 1:59 p.m. If Ο€ is truncated to seven decimal places, it becomes 3.1415926, making March 14 at 1:59:26 p.m., Pi Second (or sometimes March 14, 1592 at 6:53:58 a.m.). The Pi Day celebration includes public marching, consuming fruit pies and playing pi games... The founder of Pi Day was Larry Shaw, a now retired physicist at the Exploratorium who still helps out with the celebrations.        Pi has been calculated to be over one trillion digits beyond its decimal point. As an irrational and transcendental number, it will continue infinitely without repetition or pattern. While only a handful of digits are needed for typical calculations, Pi’s infinite nature makes it a fun challenge to memorize and to computationally calculate more and more digits. HAPPY PI DAY :)...
