Fun and engaging class game based on the old TV show Blockbusters, with questions on how to add and subtract negative numbers. These range from fairly basic ones, to questions that cross 0, to ones with three numbers to add or subtract.
Split the class into two teams, blue and white. The blue team must try to create a connected blue line from left to right, the white team must try to do the same from top to bottom. Click on the letters to link to the questions, if the answering team gets it right then click “Game board” to get back to the start, and click on the appropriate colour for that team to turn the tile blue or white.
