FREE Mini Math Debates: Promote Math Talk with 2 Digit Addition (Grade 1-3)

Promote Mathematical Thinking and Talk with Mini Math Debates for Grades 1-3 provides 8 pages of two-digit addition problems for students to analyze, discuss, and debate in pairs or small groups. Students are presented with different solving strategies and prompted to compare approaches, identify inefficient strategies, add on to existing strategies, and make connections between them. The debates encourage students to form their own mathematical thoughts and defend their thinking. This resource builds skills in mathematical discourse and evaluating reasonableness that are key for next generation assessments. Teachers can implement the debates as partner work, small group work, morning work, gifted education activities, intervention, or in centers. The debates are suitable for first graders working on place value relationships and struggling third graders needing more practice. By integrating regular math talks through these engaging debates, students become more confident mathematical thinkers.
