Art in Numbers: Multiplication Patterns

Practice your multiplication tables by creating grid paper designs from Sharynideas! Kids identify patterns in their multiplication tables. When they identify a repeating pattern, they create art! Check out the activity here! Also, visit NRich Math for a slightly different way to create designs from your times tables!

House # Math

This activity is from one of my favorite sites for real world math, Illuminations! Students create a three digit house number, using numerals 0 through 9. The three numbers they choose must add up to a certain sum. They can't repeat numbers in their combination or begin their combination with 0. For example, if their number has to equal 6, one combination might be 321. There are 14 combinations if the sum is 6. If the 3 addends must add up to 7, there are 18 combinations. Visit Illuminations for details and printables to go along with the activity.

Afterwards, incorporate measuring by having students create a "house that measures up" from Cathy Searcey. After kids make their "house plan," they head outside and draw a large version of their house using sidewalk chalk. (House dimensions: 6ft. x 6ft. frame, a 3ft. x 1ft. door, and two 1ft. x 1 ft. windows).

You could also explore geometry by having students design their very own clubhouse! Click here for details!

KENKEN

KENKEN is a math puzzle created by Japanese mathematics instructor Tetsuya Miyamoto, to "improve students’ math and logic skills." You can have students work on interactive puzzles or print them. Puzzles are on 4x4 (beginners), 5x5, 6x6, 7x7, 8x8, or 9x9 (advanced) grids. Click here for more information!

Below is an example of a 4x4 puzzle. Kids practice addition, subtraction, multiplication, and division skills. They must rearrange the numbers so each row and column has the numbers 1-4 with no repeats.

Subtraction Squares



Fun, problem solving game for kids to practice subtraction skills from Learn with Math Games! This activity can be adapted to any age group. Younger kids can work with numbers less than ten. Older kids could work with 3 or 4 digit numerals.

Kids choose 4 numbers (anything they'd like) to write on the vertices of the larger square. Then, they just subtract (corner to corner). They write the differences on the next largest square's corners (where it meets in between on the line) and so on...

The big surprise is their final square! Like magic, all of the corners are the exact same numeral! Inference: See if kids can predict what will be their mystifying number before solving all their squares! Visit Learn with Math for a free template!

Number Neighborhood



Improve number sense by making a number neighborhood by Mango Math! Kids write a number in the center circle. Then, they figure out their number's neighbors! For an added twist, have kids write numbers in different colors to represent different houses. They can even add green grass or a blue community pool if they'd like!

Perimeter Magic Triangles

Perimeter Magic Triangles - Great addition, thinking game that deals with three addends! All you need are 6 milk caps labeled 1-6. Kids slide the milk caps around, forming a triangle. Their goal is to have all 3 sides add up to equal the same sum. For another milk cap addition game, check out Magic Square Milk Caps!

Calendar Magic 9

Impress your friends with this math multiplication magic trick from Murderous Maths! Kids tell a friend to put a square around 9 numbers on a calendar (3 x 3 box). Then, they say they can find the sum of the 9 numbers within the square in a flash! Abracadabra and alakazam! All they do is multiply the number in the center of the square by 9 and presto! They magically have the answer! 



Note: For larger numbers that may be hard to do the multiplication in your head, multiply the middle number by 10 and then subtract by the middle number. For example, 11 is in the middle, 11 x 10 = 110, 110 - 11 = 99! You can do this trick on any number grid!

Magic Square

"Legend says an ancient Chinese emperor name Yu happened to be down by the Yellow River one evening when he noticed a turtle swim at his feet. The turtle had unusual marks on his shell which formed a magic square where all columns, rows, and diagonals summed to the same amount... 15. The 3 cell by 3 cell square grid pattern is called a Lo Shu magic square, representing the turtle star pattern and the Lo river." - Lo Shu Magic Square

A Magic Square is a great tactile, thinking game for kids, that has them rearrange three numerals (horizontal, vertical, and diagonal) so they all equal one sum, a magical number! I was inspired by Love 2 Learn 2 Day's milk cap magic square, so I made my own! Kids love the use of milk caps because they can slide and glide them around on a flat table top. Magic Squares are also a good way for kids to improve their addition skills using a group of addends, three whole numbers in an equation.
