Which of the following methods would best allow students to participate equitably in solving multiplication problems?

Encouraging discussion about different strategies used fosters an inclusive and collaborative classroom environment where all students can actively participate. This approach allows students to share their thought processes and methods for solving multiplication problems, which can enhance their understanding and help them learn from one another.

By facilitating discussions, teachers can address various levels of comprehension and support students who may struggle, while also allowing more advanced students to refine their understanding by explaining concepts to their peers. This method acknowledges that there are multiple ways to approach a problem and values each student's contribution, promoting equity in participation.

The other methods do not provide the same level of equitable participation. For instance, solo testing emphasizes speed over understanding, potentially alienating slower learners. Group-based quizzes might lead to competition rather than collaboration, while instructing students to copy solutions undermines the learning process and does not encourage students to engage with the material meaningfully.
