## Battleship Teaches Strategy, Sportsmanship, and Basic Coordinates

Battleship is the best game I know of to introduce basic coordinate geometry. And it’s a lot of fun. If for some reason you’ve never played it: Each of two players places ships in a “sea” of labeled rows and columns. Then players take turns guessing where the other player’s ships are. Players are required to say whether a guess is a “hit” or a “miss” and whether a “hit” results in a sunk ship.

There’s some strategy involved; you have to be careful not to inadvertently let slip a detail that could help your opponent. (My five-year-old is terrible at this.)

And of course the game can be good for learning sportsmanship. A significant amount of luck is involved, so hopefully kids learn to be gracious if their opponent gets lucky and wins.

My five-year-old is not quite ready to play on his own, but he enjoys playing teams with an adult.

Of course you can pick it up through Amazon (paid link) if you don’t have an old set laying around.

## Visualize Digits and Multiplication with Wood Cubes

Raising a child helps you remember just how hard it was to learn certain things. Most kids pick up counting to ten without much problem (after they learn to talk). But grasping double-digit numbers (and beyond) is a greater conceptual challenge. Now you have to be able to count groups of ten (and then groups of a hundred, and so on) and represent them with digit placement. Later on, multiplication (and then exponents) build on a child’s earlier conceptual knowledge.

I’ve found that a pack of wooden cubes can help illustrate the relevant concepts nicely. When a child can see, for example, two sets of ten blocks, plus three extra blocks, the child can more-readily grasp the number 23. One issue I’ve seen is confusion about the number 23 versus the addition of 2 and 3; the difference is very easy to show with blocks. Of course the blocks are also really good for practicing simple addition and subtraction.

## DragonBox Apps Make Math Fun

I absolutely love DragonBox math game apps. They make math concepts intuitive and fun. My brother used them for his kids and sang their praises, so I got them too. Here I review the four apps aimed at children ages 4 to 9: Numbers, Big Numbers, Algebra 5+, and Magnus’ Kingdom of Chess. The company also has apps for advanced algebra and for geometry; I’ll buy those down the road when my child is ready for them. The app is available for various devices; here I provide links to Amazon for those with suitable Amazon devices.

## The Place for Bob Books

Great literature Bob Books are not. But that’s not their purpose. Their purpose is to hold children’s hands during their first journeys into reading. And for that they’re great.

These very-short books turn simple words into simple sentences with just enough story and humor to hold a child’s interest for the few minutes it takes to read one of them.

I picked up Sets 1–3, plus a kindergarten set, used via eBay. For months they sat on a shelf. Several times I tried but failed to interest my four-year-old in them. I think their usefulness is all about timing.

My child, now five, has learned the alphabet and can recognize and write lower and upper case letters. Most of the time he associates the correct sound with a letter, although he still sometimes mixes up the similar-looking letters d, b, and g. He is just now gaining the ability to string together the sounds of letters into words. I am reminded of how hard this can be in English (as opposed to, say, Spanish), what with all the different possible letter sounds—we pronounce (for example) “one” the same as “won.” Bizarre.

I tried again to interest my child in a Bob Book—and this time he was receptive. In two days he’s read the first four books. I figure we’ll aim to read two or three per day until we finish. Then if he wants to start over, great; if he wants to be done, also great. I consider the Bob Books as a transition to him reading for himself his first “real books.” Once the Bob Books have served that purpose I’ll pass them along to the next child.

So, to summarize my advice: Get a a few Bob Books (paid link) (or something comparable) when your child is learning the alphabet and the letter sounds. Check in with your child every week or so to see if the books seem interesting. When and if they do, go for it. But don’t overdo it; I’ve found that reading through a single book in one sitting is actually fairly taxing for the child, though it takes but a few minutes. When the books no longer hold the child’s interests, move on to something more substantive.
