## 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.

## Multiplication Game (November 9 thru 15th) 1st through 5th Grade

The Mathletes were very excited about the Multiplication Game I introduced this week. The attached pdf explains the rules and has game boards. All you need is dice. The pdf allows you to create your own dice of 6 or 12 sides. If the game is played with 6-sided dice the children are reinforcing the multiplication table to 6x6. If they use the 12-sided dice, they are working with the multiplication tables up to 12x12. The pdf also gives them a blank multiplication table with answers for practice.
