This is a new station for practicing computation.This set focuses on adding integers and includes four different Roundabouts, each with eight problems. It is self checking in that the pieces fit together, linking problems with correct answers to form a circle. In this file they are in the correct order. Print a copy and leave it together to use as a key. If a student successfully solves all the problems they will be in this order.
My station rotations are in groups of four. Roundabouts make a great individual practice station. That is, when a group gets to this station, each student grabs a set of Roundabout pieces and gets to work. They can switch if two finish with time left at the station. You could also have the students work in partners or groups of four.
I have included two versions. In the first, the problems and answers are in corresponding colors. That way, if a student drops an answer, you know which Roundabout it belongs to. In the second version, all the problems and answers are in black. Here you can print them on four different colored sheets of paper. I laminate the included student directions to keep at the station. There is also a sheet for students to record their work.

Apply and extend previous understandings of addition and subtraction to add and subtract rational numbers; represent addition and subtraction on a horizontal or vertical number line diagram.
Understand p + q as the number located a distance |q| from p, in the positive or negative direction depending on whether q is positive or negative. Show that a number and its opposite have a sum of 0 (are additive inverses). Interpret sums of rational numbers by describing real-world contexts.
Understand subtraction of rational numbers as adding the additive inverse, p - q = p + (-q). Show that the distance between two rational numbers on the number line is the absolute value of their difference, and apply this principle in real-world contexts.
Apply properties of operations as strategies to add and subtract rational numbers.
