Nriching our virtual classrooms!

Krittika Hazra

Here are some maths classroom resources from an amazing website called Nrich (https://nrich.maths.org/). If you have not visited this website yet, please take a look immediately! It has an enormous collection of teacher and student resources such as worksheets, live problems, activities, games, articles and interactives. While these resources are mainly for offline classroom use, the website also has a number of games and interactives which students can explore virtually. The ideal scenario is the offline version of the games when the opponent is your friend, but I was more than happy with the online versions in the virtual classroom too! These are a few games which directly relate to the curriculum and can be played by the students by themselves during the class. I have tried these in my class, and my tech-savvy students just loved them! Try it in your class by sharing the link with the students in email or in Zoom chat.

  1. First connect three: https://nrich.maths.org/5865

Topic: Addition and subtraction of integers

Class: 6, 7

In this game the player who first completes a row of three squares, either horizontally, vertically or diagonally is the winner.

Spin the spinners, place each number in one of the squares and decide whether you want to add or subtract to produce the total shown on the board.

2. Factors and multiples: https://nrich.maths.org/factorsandmultiples

Class: 6

This is a game for two players. The first player chooses a positive even number that is less than 50 and crosses it out on the grid. The second player chooses a number to cross out. The number must be a factor or multiple of the first number.

Players continue to take it in turns to cross out numbers, at each stage choosing a number that is a factor or multiple of the number just crossed out by the other player.

The first person unable to cross out a number loses. Though this game does not have an online version, the students can share screens in Zoom breakout rooms and annotate with two different colours to strike out the numbers.

3. Matching fractions, decimals, percentages: https://nrich.maths.org/1249

Click on a card to turn it over. Then click on another one. If the two cards match, they will stay face-up. If they don’t, they will return to their original positions, face down. The game ends when all the cards have been matched in pairs. It has till level 5.
