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.

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.

1. I should have at least try this game. My sister said it was boring and she did not get any tickets either. lol.. I think it was educational you learn adding. For children you should have smaller numbers..Good post

• Please apologize to your sister for me! The game just stopped working for her and I forgot to give her tickets.

I forgot to link to it in the post, but it’s still online if you want to give it a spin.

• That’s all right, but gave her the toy..Thanks for the link I can play it now…

2. Nice game! I know you had to put a lot of time into it, computer programing is not easy. This was my favorite game, it was original too.

• Wow, thanks! There were so many great games that I’m really surprised to hear that.

3. I did not get a chance to play your game but my son enjoyed it. He was impressed that you made a game on your computer…so was I! I think this game is great for 3rd and 4th graders because it lets them practice what they’re already suppose to know. At this grade level they should be fast and accurate with addition facts and your game gives them the practice. You have great ideas on how you would like to modify the game – Good Luck!

• Your son did great, I was impressed! I was afraid it was going to fast, but he was really hanging in there crunching out answers.
