B. Record a number line scenario as a -0 subtraction equation

C. Record a number line scenario as a subtraction equation with a difference of 0

D. Identify missing numbers in subtraction equations with a difference of 0

E. Subtract by moving an object backward on a number line and solve a related equation that shows subtraction from 3, 4, or 5

F. Record a number line scenario as an equation that shows subtraction from 3, 4, or 5

G. Record a scenario based on objects as a subtraction equation with a difference of 0 (Part 2)

I. Solve equations based on a model of base-10 blocks to subtract 1 or all but 1

J. Record a model of base-10 blocks as two related equations that show subtraction from 6
