K/1st Grade Diagonal Square Patterns (December 16th)

The children explored patterns in numbers placed diagonally in a pyramid like grid (see attached pdf).

They should create these diagonals in 7x7, 9x9, up to 15x15 grids and go pattern hunting.

They also received large graph paper in class that they can use to make their diagonals.

In addition, they all received a tennis ball that they wanted to decorate with math related drawings.   This can include numbers, shapes, diagonal squares, or anything they want.

Kindergarteners Add Magic Squares Numbers (December 9th)

Kindergarteners should choose rows, columns or diagonals in the Magic Squares Patterns.pdf and add the numbers using the vertical method.  


  1. have the children copy the numbers vertically by lining up the ones place, tens place, etc.
  2. add the ones place numbers first
  3. put the ones place from the sum in the total and carry the tens place number on the top of the next column.
  4. add the tens place numbers including the carry number and put the result in the total.


Magic Squares of Odd Order (December 6 to 9)

Have fun with this completely different algorithm for finding odd ordered magic squares.  The Word document provides up to 21x21.


Magic Squares of Even Order (November 29 to December 2)

The students heard the story of Chinese Emperor Yu who found a turtle in the year 2200BC with a magical puzzle on its shell.  The pattern was a three by three grid with dots numbered from 1 through 9.  Each row, column, and diagonal had the same sum.  This magic number 15 was instrumental in bringing good luck to the people of China living on the Yellow River.

Multiplication Magic Squares (November 16th to 20th)

The Mathletes continued their exploration of multiplication this week with Multiplication Magic Squares where a two by two grid contains 4 numbers which when you multiply them horizontally or vertically they have a product of the numbers outside the grid.

The challenge is that the boxes inside are empty, so students have to look for common factors of each number and then see if the rest of the puzzle falls into place.
