FREE What's Missing? | Building Thinking Task Cards | Inference & Reasoning Activities | Grades 3–8

Help students become stronger thinkers by teaching them to look beyond what is given and identify what information is missing.

These engaging Building Thinking Task Cards challenge students to analyse incomplete situations, identify gaps in information, and develop logical explanations using clues, evidence, and reasoning.

Students investigate scenarios such as a student who suddenly stops participating in group work, a successful team that begins losing games, a mysterious note that says "Don't trust them," and a classroom terrarium where plants are unexpectedly wilting. Rather than jumping to conclusions, students learn to ask better questions, consider multiple possibilities, and justify their thinking.
