Number chart patterns


Are you looking for creative ways to help your children study math? Just spend an afternoon playing around with a hundred chart also called a hundred board or hundred grid. Take turns making up problems for each other to solve. Develop mental math skills by showing how to add or subtract the tens first counting up or down then the ones counting left or right. What do you notice? What do , , , etc. Count by 5, starting at Or count by 2, but start with Or for a tougher challenge, practice your mental subtraction skills: You could make an even numbers chart, or a multiples of 3 chart, or.

What does it mean to count from one number to another? When you count, do you include the first number, or the last one, or both, or neither? Talk about inclusive and exclusive counting, and then make up counting puzzles for each other. Repeat to make a design. Now, let your student make up a puzzle for you to color. Cut up a hundred board into irregular pieces to make a puzzle. For more of a challenge, cut a blank chart into puzzle pieces, writing in one or two numbers per piece.

Can your student fill in the rest of the numbers? Refresh your screen to get a new set of numbers. Starting at the number given, each arrow means to move one square in the direction shown. Make up your own arrow code for someone to follow. Count by dimes or by quarters, or use the chart to make change for a dollar.

If you correctly predict your landing place before you move without counting squares! The first person to reach or pass wins the game. If your token is starting on an odd number, move that many spaces forward. From an even number except 2 , move backward — but never lower than the first square. If you are starting on a prime number including 2 , you may choose to either add or multiply the dice and move that many spaces forward.

Ali Adams in a comment on another post. Take turns pointing to any number. The other player has to say how many more it takes to make Colored disks are nice for this, or use pinto beans. Mark the numbers you hit when you count by 2. What pattern do they make? Make the counting-by-3 pattern, or mark the 7s, etc. You may want to print several charts so you can color in the patterns and compare them. Why does the counting-by-5 pattern go down the way it does? Mark the multiplication patterns by putting colored dots along one edge or corner of each square.

That is, all the multiples of 2 get a yellow dot, for instance, and the multiples of 3 get green dots… Which numbers have the most dots—that is, have the most factors? Which numbers have just one dot? On a printed chart, blacken the box for the number 1, which is neither prime nor composite. Circle the next unmarked number 3 , and then cross out all of its multiples.

Keep going until every number is either circled prime or crossed out composite. The first player marks an even number less than 50 on the hundred board. His opponent marks a factor or multiple of that number. Players alternate, each time marking a factor or multiple of the last number played. The player who marks the last number, leaving his opponent with no move, wins the game.

Try to find the longest possible chain of factors and multiples. Keep track of the order in which you mark the numbers. Can you find a way to mark 50 or more without breaking the chain? How do you know? How can you show it is true? What does any fraction mean? What other fractions of can you find? Do you see how? If we say that the chart is one whole unit, then how much is each row in decimal notation? What size is each box? Can you color 0. And what percent of the chart would that be? An X pattern is a square plus the four touching it diagonally.

Choose any square that is not on an edge of the hundred board. Find its Cross and X patterns, and add up their sums.

Can you explain why they add up to the same number? Can you find any other patterns that work that way? Can you figure out how to predict the Cross or X pattern sum for any number? How are these the same as on a hundred board? How are they different? Then make up some puzzles of your own. Use a wide-tip marker to make Xs and Os, or use pennies and nickels to mark the squares.

On each turn, the player must make up a calculation that equals the number in the square he wants to mark. Can you think of anything else to do with a hundred chart?

Can your student find 10 bones numbers on a blank hundred chart before the time runs out? Amy at Early Bird Homeschool. Tonia at The Sunny Patch. Use 4 crayons or colored markers and a hundred chart to keep track of which lights glow for which numbers. Can you figure out the rules? Can you find a number that makes all the lights come on? Hit the Restart button to get a new set of rules. Player 1 marks any number and writes that down as his score, then Player 2 marks all the factors of that number which have not been previously marked and writes their sum as her score.

Player 2 marks an open number, adding that to her score, and then Player 1 marks any factors that are available and adds them to his score.

Play alternates until no numbers remain. At that point, whoever has the highest score wins. What if the player who is claiming the factors misses some? Should we allow the other player to claim those numbers as penalty points?

Seems fair to me! Hang it on the wall, low enough that your preschool or early-elementary student can see it easily. Talk about the patterns your child notices. Challenge your students to deduce the secret behind each pattern of shaded squares. Then have them make up pattern puzzles of their own. Free registration required to download pdf printable. Add up the numbers to get your score. Then try to find a different set of ten Sudoku-style squares.

What do you wonder? Should the hundred chart count or ? Tricia Stohr-Hunt, Instructional Conundrum: Have another math debate: Which way makes more intuitive sense? Try a counting pattern, or Race to game, or the Sieve of Eratosthenes on the number line. Have a new math debate: Grid chart or number line — which do you prefer?
