## Tiling Rectangles with Integer-Sided Squares Algebra and Perfect Rectangles

Algebra is the mathematics of using letters to represent possible numbers to solve complex problems.

We had the K-3rd graders look at one or two values of square dimension and then fill in the rectangle with all square dimensions using the information given. For example, if a square shared a side with two other squares with dimensions of 3 and 4, that larger square has a dimension of 7. If a square has a dimension that is the difference between a larger square of 10 and a smaller square of 3, its dimension is 7. Then we use a "work around" strategy to complete the puzzle.

## Tiling the Rectangle into Smallest Number of Squares of any Dimension

What is the smallest number of squares of any size we can dissect a rectangle of a given dimension? This was our challenge this week as we explored the strategy of breaking up rectangles into the largest squares possible in order to minimize the number of squares.

## Cake Method: Converting Any Decimal Number to Any Base Number Using Repeated Short Division

When I was your children’s age and I discovered the short division method, I became entranced with dividing any number by 2 and then dividing that quotient by 2 and so on. I began dividing each number right on top of the other and it resembled a multi-tiered cake.

## Short Division by 2, 3, 5, 11, 17, and 36 with and without Remainders

Ever since I was in 2nd grade and became fascinated by division, my teachers were relentless in their preoccupation with long-division. I could not believe that this was the fastest way to do division without a calculator so I endeavored to develop my own strategy I call “short division.” Why is it better?
