This packet includes 10 separate worksheets, each with an answer page included. All pages have a sea life themed question, which can be answered by solving addition problems.
This packet could be given to students all at once, for students to work on at their own pace, or pages could be used one at a time when students are ready for them. The last three pages increase in difficulty (see details).
Each worksheet has between 9 and 11 addition problems on it.
All problems add 2 numbers together, each with 2 digits.
On the first 7 pages, all problems require regrouping. On the last 3 pages, only some problems require regrouping and some answers have a hundreds place.
