Open Middle: Horizontal and Vertical Distances (V1)

Creation of this Open Middle exercise was inspired by a problem found in the Grade 6 iReady math curriculum published by Curriculum Associates.
Using digits -9 to 9 no more than one time each, fill in the boxes below to make all statements true. Note: Only positive digits can be placed in the last 3 boxes. Points (soon to appear) are draggable.
Can you create another valid setup that is different from the one above? Try to do so!
What is the greatest possible value you can get for the DIFFERENCE BETWEEN the distances AB and CD (bottom right most box)? Try to make this value as large as you possibly can!

Open Middle Midpoint Exercise (V1)

Creation of this resource was inspired by an Open Middle problem posted by Dane Ehlert.
Find locations for A and B so that M = (3,4) is the midpoint of the segment with endpoints A and B.
Find other locations for A and B so that M = (3,4) is the midpoint of the segment with endpoints A and B. Make sure your setup is different from the one you created above.

Open Middle: Two Way Table Setups

Using digits 0-9, fill in the boxes to create a two-way table below. Design this table so that NO DIGIT REPEATS MORE THAN 3 TIMES.
Using digits 0-9, fill in the boxes to create another two-way table that is entirely different from your setup above. Design this table so that NO DIGIT REPEATS MORE THAN 3 TIMES.
Using digits 0-9, fill in the boxes to create another two-way table that is entirely different from your two tables above. Design this table so that NO DIGIT REPEATS MORE THAN 3 TIMES.

Open Middle: Bearings Exercise

Using digits 0-9 NO MORE THAN ONE TIME EACH, fill in the blanks to create a true statement.
Using digits 0-9 NO MORE THAN ONE TIME EACH, create another true statement that is different from the one you made above..
Using digits 0-9 NO MORE THAN ONE TIME EACH, create another true statement that is different from the two setups you made above.
Given the no repeated digits constraint, what is the LARGEST possible bearing (0° < bearing < 360°) you can create here?
Given the no repeated digits constraint, what is the LARGEST possible direction angle (0° < direction angle < 360°) you can create here?
