Circles and Arrows show grids with two rows and three columns. In each grid, circles contain numbers or letters. Letters represent unknown quantities. Arrows point to sums of rows and columns. All rows and columns represent equations. For example, a row that shows , 4 and a sum of 10, can be represented as . Students use the grid relationships to figure out the values of the letters. There are often several ways to begin to solve each problem. Encourage students to consider alternative solution approaches and to talk about them.
