The disruption caused by the coronavirus pandemic put India’s education sector in a tight spot. It had either to adopt the new system of online education or languish with the offline one. The choice of online education ended up being a heavy burden for many schools, especially those in the under-served hinterlands, the primary reason being the absence of critical infrastructure to make the change seamless. It made critics question the sudden advocacy for digital education on a pan-India scale.

Exploring areas of rectangles, triangles, parallelograms and trapeziums including some ignored aspects. Models can be made using stiff paper/card/boxes.

Multi-digit divisors are neglected in some syllabi and textbooks including the NCERT ones. They pose a lot of challenges and provide the only case when a standard algorithm of any of the four operations requires estimation. While the skill of dividing with such divisors may have lost its relevance thanks to the prevalence of mobiles with calculators, it is debatable whether they should be completely removed from school math. This ppt explores how to tackle such divisors and includes all possible estimation scenarios.

Division can be explored using array. This further establishes the reverse process of multiplication. It also brings out dividend = divisor x quotient + remainder beautifully. Check the ppt for all these and more...

 Prospective authors are asked to observe the following guidelines.

1. Use a readable and inviting style of writing which attempts to capture the reader's attention at the start. The first paragraph of the article should convey clearly what the article is about. For example, the opening paragraph could be a surprising conclusion, a challenge, figure with an interesting question or a relevant anecdote. Importantly, it should carry an invitation to continue reading.

 We feature here Mathematics teachers who we encounter in the course of the Foundation’s work, unsung heroes and heroines who are often the gateway into and out of mathematics for many a student. Math phobia has been endlessly discussed, it is time to focus on those whose dedication to the subject creates lifelong learners.

Many elements in buildings – beams, pillars, windows, doors, window bars, flooring tiles – incorporate parallel lines. Line dividers on roads, railway lines, power lines are all examples of parallel lines. Parallel Lines assume a lot of importance when marking out roads or pedestrian crossings, sports courts, athletic tracks and airport runways.

Ever since we decided to reintroduce our readers to Numberphile (https://www.numberphile.com/), I have been obsessively watching videos hosted via YouTube on the site! I have also listened to some podcasts. The content is both mathematics and interviews with mathematicians about a range of topics from“Why do people hate mathematics?”to “Fame and Admiration."

Arrow cards are a simple manipulative to grasp place value or more generally the base-ten number-writing system that we use. Dr. Maria Montessori invented the static cards shown in Figure 1. These cards are used along with proportional material like static beads (unit = single bead, ten = 10 beads strung together forming a line, hundred = 10 tens strung together to form a square and thousand = 10 hundreds strung to form a cube) to gain a sense of numbers – the quantities they indicate and the numerals that represent them and how they are linked.

The relevance of this book to my work is due to the fact that it is a terrific blend of conceptual understanding of fractions and the challenges faced in classrooms by the teacher during transaction of this concept. It made me re-visit my experiences in the field of education. This book has dual insightsdata from cited research studies as well as from classroom work and is a valuable resource both for teachers as well as for teacher educators. Threads have been tied beautifully from start to finish of each chapter.
