What this worksheet covers
Sixteen addition problems fill the page, and the complete key sits behind them in the same PDF. Within that, fifteen of the sixteen problems require regrouping and the rest do not, so the two cases are mixed rather than blocked together; numbers reach 9,826. The whole sheet sits inside Common Core 4.NBT.4, in the grade 4 Number & Operations in Base Ten strand.
Skills practiced
At this point in the sequence, work in addition is really about the standard algorithm with regrouping. To finish it, a student has to carry or borrow across place-value columns without losing a digit. Speed matters less than a clean method that survives a harder problem.
How to use this worksheet
By grade 4 a student should be able to take all sixteen problems in one sitting. Time it loosely — if the page takes more than about fifteen minutes, the underlying facts are probably not automatic yet, and that is worth fixing before more addition practice piles on top. Keep the key face down until the page is finished, then go through the misses together rather than only totalling the score.
One mistake to watch for
Counting all instead of counting on: for 7 + 3, the student starts at one.
Cardinality has not fully transferred — the student does not yet trust that "seven" names the whole set and can be the starting point.
Hide the first set under a cup, label it with the numeral, and count on from there. When the set cannot be counted, counting on is the only option available.
