## Sector Area 2

Directions: Using the digits 0 to 9 at most one time each, place a digit in each box so that the radius and angle measure result in the sector area is as close to 60 units2 as possible. Source: Robert Kaplinsky

## Area on a Coordinate Plane 2

Directions: Using the integers -9 to 9 at most one time each, fill in the boxes to create coordinates that represent the vertices of the triangle with the smallest possible area. Source: Robert Kaplinsky

## Perpendicular Lines 2

Directions: Using the digits 0 to 9 at most one time each, fill in the boxes to create two perpendicular lines whose solution is as close to the origin as possible. Source: Robert Kaplinsky

## Equation of a Circle 2

Directions: Using the digits 1 to 9 at most two times each, place a digit in each box to make a circle with the least possible area. Source: Robert Kaplinsky

## Properties of Exponents 4

Directions: Using the integers -9 to 9 at most one time each, fill in the boxes to make an equation where the product’s exponent has the greatest possible value. Source: Robert Kaplinsky

## Systems of Inequalities 2

Directions: Using the integers −9 to 9 at most one time each, place an integer in each box to create a system of inequalities as well as an included and excluded point. Make the points as close together as possible. Source: Robert Kaplinsky

## Systems of Equations 4

Directions: Using the integers −9 to 9 at most one time each, place an integer in each box to create a system of equations whose solution is as close to the origin as possible. Source: Robert Kaplinsky

## Arithmetic Sequences 2

Directions: Using the integers −9 to 9 at most one time each, place an integer in each box to create an arithmetic sequence so that the coefficient in the function that represents it is the greatest possible value. Source: Robert Kaplinsky
