## Logarithm Laws 2

Directions: Using the digits 0 to 9 at most one time each, fill in the boxes so that the values of each expression increases from least to greatest. Each number may only be used once. Source: John Rowe

## Solving One-Step Equations 2

Directions: Using the digits 1 to 9 at most one time each, fill in the boxes to make a true equation where x has the largest possible value. Source: Robert Kaplinsky

## Close to 1000

Directions: Using the digits 1 to 9 at exactly one time each, fill in the boxes to make the sum as close to 1000 as possible. Source: John Ulbright and Robert Kaplinsky

## Creating Right Triangles 2

Directions: Using the digits 1 to 8 at most one time each, fill in the coordinates to create the vertices of a right triangle: A(__, __), B(__, __), C(__, __) Extension: Try to do this using only the digits 1 to 6. Source: Erick Lee

## Creating Rectangles 2

Directions: Using the digits 1 to 8 at most one time each, fill in the coordinates to create the vertices of a rectangle: A(__, __), B(__, __), C(__, __), D(__, __). Extension: What is the rectangle with the largest/smallest area/perimeter that you can find? Source: Erick Lee
