Print: Ages 8–9 · 2–3 min · Core · Constant rate · Independent practice · Find the total

Watch: Watch whether the learner enters 7 after using 42 ÷ 6. That response shows they found the covered number of bags but stopped before finding the total under 8.

Misread: A response of 8 suggests the learner copied the “pencils in each bag” header; 42 or 70 suggests they copied a known total. The answer must be the missing total under 8, not a header, row factor, or neighboring cell.

Curriculum: This task develops multiplication-table structure: one row factor is shared across all columns, and a missing product is found through the multiplication–division relationship. The scored skill is entering the exact missing product, 56.
