The goal of this playable lesson plan is to help improve ones mental addition speed. Addition is an everyday tool that we use, and even though almost all of us walk around with calculators on or phones or laptops, it’d still be faster to just do simple sums in our heads.
So I came up with a adding game called Adder-All.
The game works by having a summand fall from the top of the screen towards the bottom. The goal is to enter the sum before it falls off the screen. As the player progresses the summands fall ever faster, forcing the player to think fast or it’s game over.
Each time the player correctly answers a bonus multiplier is used to calculate the score. For example, if the player gets 10 in a row correct, then the points for the next correct answer would be 11 x [number of points for correct answer]. It’s an incentive to be extra precise in their calculations, and the best way to get to the top of the leaderboards.
The game is pretty ugly right now, so I’d like to modify it to make it look nicer. It could also use a bail out feature, like by hitting space to stop the summand from falling, giving the player a chance to save a life. I’d also like to add more bonuses, like the ability to earn extra lives.
The game doesn’t teach the player how to add. I thought about having a summary of the wrong answers at the end, with visuals of the expression and the sum. But I didn’t have time to do this. The lesson here is mainly to get to a new level of comfort and confidence with addition.
