Triangle Numbers (Interactive Whiteboard Game)

This is a fun interactive whiteboard game, created in PowerPoint, with triggered animations. All my students have loved this activity ('Sir, can we play the chain-game?'). It is enjoyable for both high and low ability – it not only helps familiarise students with the triangle numbers, but they also need to remember where the numbers are hidden!
--
I typically use this activity as a starter and then as a plenary at the end of the lesson. It gets the whole class involved – even when it's not a students turn, they are repeating the numbers in their head and they are desperate to say where the next number is!

The way that I play the game:
1. I go through the members of the sequence and ensure that the students are familiar with each of the numbers;
2. When the board is revealed, I give about 15 seconds to ‘peek��� at the uncovered board so that the students can try to learn where the first few numbers are;
3. I then call up the students one-at-a-time to try an uncover as many numbers as they can before they go wrong.

NOTES:
I encourage the students to call out the number that they are looking for because this reinforces the learning.

This activity works very well if you get two students to play against each other ��� either on the interactive whiteboard or on PCs.
