Students solve a set of 4 equations and then add up the answers to see if they get the target sum. Can be done in small groups or independently. No negatives and a few questions have fractions. The sets of problems get progressively more challenging.
Option 1: Group Work.
Place students in groups of 4. Each student solves problem #1. When they are finished they put their pencils down until the teacher says pass. They then pass the papers clockwise and complete #2 on their new paper. This repeats until all 4 problems are complete. Then students add all 4 answers from the row and compare their sum. If their sums are not ALL the same, they need to go back and check each equation as a group until they all agree on the answers. When they all have the same answers, they pass the papers again and repeat the steps with each row.
Option 2: Group Work.
Students work in groups but on their own paper. Students check their sums at the end of each row as a group. If their sums are not ALL the same, they need to go back and check each equation as a group until they all agree on the answers. When they all have the same answers, they continue working on the next row of problems.
Option 3: Independent Practice.
Students work on their own. At the end of each row, students check their sum with the teacher. If the sum is correct, they move on to the next row but if it is not they go back and check their work. Students can raise their hand to get the sum checked or have the sum written on a piece of paper in the room where they can check their answer.
