A Math Worksheet for 3rd Grade

One of the things that has been visited upon us as Firstborn makes his way through Third Grade is the concept of "Math Facts". Apparently, we're supposed to spend half an hour each week going over "math facts". I dunno, maybe they think we own flash cards or something. Mostly, we've been trying to do the sorts of things we see in his homework, except on a more ad hoc basis. I, however, am just about as bored with that as Firstborn is. So, in an effort to make things a bit more interesting, I've created a worksheet. If you're a parent in roughly the same position, feel free to nick it for your own use.
1. A Gunzerker, a Commando, and a Siren follow a stolen power core to a bandit camp. The Commando takes care of 9 bandits. The Siren takes care of 14 bandits. The Gunzerker takes care of 12 bandits. The Commando also tosses out 2 turrets. Each turret takes care of the same number of bandits as the Gunzerker did. When they are done, all the bandits are gone. How many bandits were in the camp? Show your work.

2. Your new, Creeper-proof tower is 8 blocks wide and 12 blocks deep. How many blocks will it take to fill in the floor?

3. In Terraria, your Super-Mystic Ebony Blaster-Wand deals 15 damage every time it hits. If the Eye of Cthulhu has 128 hit points, how many times will you have to hit the Eye of Cthulhu in order to defeat it? Show your work.

4. You have finished your homework and done your chores. You now have 35 minutes to watch YouTube videos. If every video on your favorite channel is 7 minutes long, how many videos can you watch before it's time to go to bed?

5. Speaking of YouTube videos, which will take the longest to watch?
‭ 3 videos which each last 11 minutes
‭ 2 videos which each last 15 minutes
‭ 5 videos which each last 7 minutes
‭Show your work.

‭6. Your new life-form in Spore has 4 arms, each of which has 4 claws. How many creatures will you need in order to have 48 claws? Show your work.

I'll let you know how that works out for us.

  1. Worked out pretty well, by the way. It took Firstborn almost exactly half an hour to finish it.
