Tie for Two:
A and D go to the next hundred on the number line
A and C, both benchmark numbers are in the hundreds
A and C, the numbers are hundreds
A and C both show numbers that are more than halfway on the number line
A and D have 9 in the tens place
A and C have 1 in the hundreds place

Thread for Three:
A, B, and C round up to the next ten
A, B, and D all have a place value benchmark on the number line
A, C, and D all have numbers in the hundreds place on the number line

Fit for Four:
All four are counting by tens on the number line
All the numbers fit on the number lines
All of them don’t have “halfway” marked
The all have different digits in the ones place
