## 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!

## Morning Coffee – 4 November 2019

One of the best ways we can help our children learn mathematics (or anything else) is to always be learning ourselves.

Here are a few stories to read with your Monday morning coffee:

“Games aren’t just about practice and fluency. My favorite games create opportunities for learning, too. They spark discourse, promote the use of strategies, and allow students to dig into the mathematics.”

• Have you read Pam Harris’s Development of Mathematical Reasoning series? Check out Part 1, Part 2, and Part 3. Well worth your time!

“The teacher’s role is to help students change the way they think, in increasingly sophisticated ways. The goal is not answers. The goal is development. We don’t need students who can just answer a multiplication question, we need students who can reason multiplicatively.”

## Playing with Math @ Arithmophobia No More

Check out the latest carnival of playful math for all ages:

Sonya put together this carnival of mathematical fun with numbers and shapes, delightful books, and games for all ages.

“There are two types of math games/activities. The first type of game is primarily for practicing math facts. It’s my least favorite math game … The other type of math game develops mathematical thinking. Those are my favorite. They are the kind of game/activity that makes everyone want to play.”

—Sonya Post

Each monthly Playful Math Education Blog Carnival brings you a great new collection of puzzles, math conversations, crafts, teaching tips, and all sorts of mathy fun.

It’s like a free online magazine of mathematical adventures, helpful and inspiring no matter when you read them. Enjoy!

### Help Us Keep the Carnival Going

The Playful Math Blog Carnival wants you!

The carnival is a joint effort. We depend on our volunteer hosts to collect blog posts and write the carnival each month.

Putting together a blog carnival can be a lot of work, but it’s a great opportunity to share the work of bloggers you admire and to discover new math-friends online. I love that part of being a host!

Classroom teachers, homeschoolers, college professors, unschoolers, or anyone who likes to play around with math — if you would like to take a turn hosting the carnival, please speak up.
