I created these to use in conjunction with my Investigations Unit 1 (Session 4), but they can be used independently outside the program.
Each page is labeled and sectioned into 6 squares. These can be cut apart and used in a center with students, or printed whole page to be used as an activity sheet. Space is provided in each square for students to show their work.
1 page of "connecting" problems
1 page of addition only
1 page of subtraction only
2 pages of mixed problems
2 pages of "challenge" problems (repeated addition, adding 3 numbers, background knowledge of calendar, etc)
*For most problems, sums are up to 20 (excluding the "connecting" problems and challenge problems)*
