Directions: Using the digits 1 to 7 at most one time each, place a digit in each box to create an inequality that match the solution of the inequality on the number line. Source: Jay Sydow

Directions: Using the digits 1 to 9 at most one time each, place a digit in each box to make a true statement. Source: Owen Kaplinsky

Directions: Using the digits 1 to 9 at most one time each, place a digit in each box to make a true statement. Source: Owen Kaplinsky

Directions: Using the digits 1 to 9 at most one time each, place a digit in each box to make a triangle with side lengths that give the corresponding area. Source: Owen Kaplinsky

Directions: Using the digits 1 to 9 at most one time each, place a digit in each box to find the second greatest solution. Source: Neil Hamilton

Directions: Using the digits 0 to 9 at most one time each, fill in the boxes to create supplementary and complementary angles where the measures of each pair of angles are as close together as possible. Source: Brian Anderson with Robert Kaplinsky

Directions: Using the digits 0 to 9 at most one time each, fill in the boxes to create a circle with the smallest difference between the area estimates. Source: Robert Kaplinsky

Directions: Using the digits 0 to 9 at most one time each, fill in the boxes to create two possible circles. You may reuse all the digits for each statement. Source: Robert Kaplinsky
