This is a center activity that provides addition practice with 1-3 digit numbers. Each house has a tree on each side of it. Children must add the numbers on the trees to find the house numbers.They can use a number of strategies of their choosing to find the correct number. This is a good activity for stratch paper or calculators. Once the house number is calculated, the children put the house number above the door.
The center is appropriate for second and third graders. It can be used in groups or as an individual activity. Most of the equations add hundreds to a number (e.g. 500 + 48) , so it lends well to mental math for all but 2 equations. Since the children do not have to regroup, I have allowed first graders to work this center. (end of year)
The Common Core Standards are listed, as well as the standards for Oklahoma. You can copy off the standards that meet your needs. There is an answer sheet, instructions for assemblying this center, and directions for using it in the classroom.
I put velcro above each door and on the back of each number. This keeps the pieces from being lost. It also adds an extra dimension to the game.
My students enjoy this activity. It is used often.
