## Playing with a Hundred Chart #35: The Number Grid Game

This is a pretty simple game, but it makes a nice variation on the Race-to-100 game for young children who need to work on counting by tens from any number.

### How to Play

You’ll need a 6-sided die, a hundred chart (printables here), and a small token to mark each player’s square. A crumpled bit of colored construction paper works well as a token.

Take turns rolling the die. If you roll:

• 1: Move either 1 or 10 squares, your choice.
• 2: Move either 2 or 20 squares.
• 3–6: Move that number of squares.

The first player to reach the final square by exact count wins the game.

Variation #1: For a shorter game, the first player to move off the board wins. You don’t have to hit the final square by exact count.

Variation #2: For a longer game, if you cannot move your full roll forward, you must move backward. Rolling 6 is a “wild card” — you can move any number from one to ten.

Variation #3: Count down. Start at the highest number on your chart and subtract each roll, moving toward zero. If you have a chart like the original shown above, a player whose move goes past zero into negatives will add the number on their next roll.

### More Ways to Play on a Hundred Chart

A hundred chart can provide mathematical play from preschool to high school. The list on my blog began many years ago with seven activities, games, and logic puzzles.

Wow, has it grown!

## New Math Board Game: MULTI on Kickstarter

If the math classic The Product Game got together with Ultimate Tic-Tac-Toe, this game would be their child.

According to game creator Federico Chialvo, “MULTI is a fantastic 2-player math game designed with the joy of mathematics in mind. This game is so fun your kids won’t want to stop playing, and neither will you!”

Originally designed for students in 2nd-5th grade, MULTI helps children develop fluency with multiplication facts and the relationship between multiples and factors. Even better, the rich strategy and gameplay can be enjoyed by people of all ages.

If you want to play math with an elementary-age child, check out the Kickstarter:

“Mathematics is a polarizing topic! For some, it is a fountain of wonder, beauty, and intrigue. For others, it is a cold dark thing, something to be avoided or even feared. Yet, my experience has shown that everyone can find joy in mathematics when it is presented in the right way.”

## Math Game: Place Value Fish

Math Concepts: addition, subtraction, place value to six or seven digits.
Players: two or more.
Equipment: pencil and paper.

### Set-Up

Each player needs a sheet of blank or lined paper, and a pencil.

At the top of your page, write a 6-digit number. All the digits must be different, and none of them can be zero.

### How to Play

On your turn, you go fishing for points. Ask one other player, “Give me your _____’s.” The blank is for the single-digit number of your choice.

The other player answers, “You get _____.” This blank is for the value of that digit in the other player’s number.

For example, suppose you asked for 5’s. If the other player has a 5 in the tens place of his number, you get 50 points. But if 5 was in the ten-thousands place, you would get 50,000. And if there is no 5 at all, you get zero.

You add those points to your number. The other player subtracts the points from his number.

Then it’s the next player’s turn to go fishing.

### Notice These Rules

Your number may change with each turn (except when you get zero). Always use your most recent number to add or subtract the fishing points.

If you have more than one of the digit asked for (like the player on the left above, who has two 7’s), you may choose which one to give away. That is, you can give the other player 70 points and not even mention the 7,000.

### Endgame

Keep taking turns until every player gets five chances to fish for points. After five rounds, whoever has the highest score wins the game.

UNLESS the winner made an arithmetic error.

Be sure to check each other’s math, because any player who makes a mistake automatically loses the game.

## A Puzzle for Palindromes

If you haven’t seen the meme going around, this is a palindrome week because the dates (written American style and with the year shortened to ’19) are the same when reversed.

Here’s a math puzzle for palindrome week — or any time you want to play with math:

• Print a 100 chart.
• Choose a color code.
• Play!

What do you think: Will all numbers eventually turn into palindromes?

You can find all sorts of hundred charts on my Free Math Printable Files page.

Or play with Manan Shah’s advanced palindromic number questions.

## Updated Geometric Coloring Designs (Free)

I created these coloring pages for my homeschool co-op math kids, and then collected them into a downloadable 42-page PDF coloring book for your family to enjoy.

The booklet includes several ready-to-color designs, a wide assortment of graph paper, advanced create-your-own tessellation pages, and links to all sorts of online math art resources.

But when I posted the link to Twitter, a friend noticed that several of the resource links were broken. (Thanks, Mark!)

While I was fixing those, I added some new links (to the wonderful School of Islamic Geometric Design pattern templates and classroom resources).

So even if you’ve downloaded the file before, you may want to pick up this new-and-improved edition.
