Math Facts 2

Another homemade worksheet which Firstborn can use for his weekly "Math Facts". Again, if you're a parent in a similar situation (i.e. trying to figure out how to do math facts for thirty minutes a week with your video-game-obsessed third grader) feel free to steal this for your own use.

1. In order to create a Grail Of Bubbly Power, you will need 8 silver ore. You will also need twice that much copper ore, and half that much gold ore. How many total pieces of ore will you need to make this item?

2. Your Claptrap unit has been attacked by 7 Scavs. You activate vaulthunter.exe and receive a buzz axe. The buzz axe will take care of 2 Scavs every second. How many seconds will it take for you to get rid of the scavs?

3. Vexx needs 35 wraith-hearts to open the portal to the shadow world so that he can defeat Dark Yabu. If each realm contains 5 wraith-hearts, how many realms will Vexx need to explore before he can open the portal?

4. Laval fell asleep when he was supposed to be guarding the Lion Temple. While he was sleeping, 2 wolves, 4 ravens, and 3 crocodiles snuck into the temple. Each intruder took 3 balls of chi. How many chi balls are missing because of Laval?

5. Texas has been overrun by a plague of zombie chickens. Fortunately, after reading Professor Egalitan’s Comprehensive Guide to Unlikely Undead Beings (Volume 7), you realize that zombie chickens can be satisfied with stalks of wheat or barley. (Zombie chickens: "Grains. Graaaaains…") There are 36 zombie chickens in your neighborhood. Half of them require 5 grains every night; the other half require four grains every night. How many grains will you need each night to keep the zombie chickens from turning on innocent humans?

6. A vampire moves into an apartment building. Each night, he drinks somebody’s blood, and that person turns into a vampire, who also begins drinking people’s blood and turning them into vampires. (So, on the first night, Dracula drinks Alice’s blood. On the second night, Dracula and Alice go out and drain Bob and Bill, turning them into vampires also. On the third night, Dracula, Alice, Bob, and Bill all go out and drain people. This is called a "geometric progression".) How long will it take before all 32 people in the apartment building are vampires?


  1. Very funny. I'm in no way this creative with my kiddos math work, but there are just so many of them....

  2. I'm just trying to show him how math can be used in real life. (Zombie chickens are "real life", right?)

    He wasn't too thrilled about doing the worksheet, though it's just exactly the right length to meet the school requirements - it takes him almost exactly half an hour to finish.I've promised him we can just do flash cards next week, so we may two do it in two fifteen-minute blocks instead one big half-hour activity.

  3. Something's up here. Preview doesn't seem to be working, and my comment didn't apparently publish. Once more into the breach.

    Question about problem two; is he allowed to use fractions?

  4. Weird. No, there doesn't seem to be a previous comment, and I only received a notification for this one.

    To the question: yes, but I don't think he knows how. He actually did this, more or less:
    1-2= -1
    Then he counted rows and came up with "4" for his answer. Since I'd asked "how many seconds" instead of "how long", that was what I was looking for.


Feel free to leave comments; it lets me know that people are actually reading my blog. Interesting tangents and topic drift just add flavor. Linking to your own stuff is fine, as long as it's at least loosely relevant. Be civil, and have fun!
