The final sheet applies number-line strategies to harder addition challenges within 20. Part A gives four multiple-choice questions including a number-line jump from 6, a library books word problem, and identifying a number sentence that equals 18. Part B has five fill-in-the-missing-number problems like ___ + 8 = 17 and ___ + 7 = 20. First graders pull together counting on, commutativity, and missing addend strategies to finish strong.
