Building on easy-1, this sheet pushes first graders to count on from the bigger number for slightly larger sums. Part A has eight number-line addition problems with bigger jumps that cross ten. Part B includes five fill-in-the-blanks featuring sums like 7 + 5 and missing addends such as 6 + ___ = 13. Part C ends with three true-or-false questions checking sums like 8 + 6 = 14 and reinforcing that order does not change the answer.
