This multi-digit multiplication task was used with fourth-grade students. Students are asked to critique a statement on if two numbers multiplied together are equal to two numbers added together. After an initial conjecture, students share their ideas with a partner and identify similarities and differences between the two arguments. This task contains argumentative language, including claim and evidence.

This task is designed as a think-pair-share. It sets a multiplication expression equal to an addition expression and asks students to agree or disagree about the equality. Fourth grade students are given a template to state a claim, and explain it, then compare arguments. This task can be used to open a class discussion about different ways to think about double digit multiplication. Students can look at 10×24 as (10×20)+(10×4) which would show the comparison between 10×24 and 200+40 nicely.
