# The product of squares

Throughout this inquiry students will make connections, test different cases, infer and explain rules. They will evaluate the relationship between base and index numbers and square numbers. Students multiply index numbers, being familar with index laws and rules. Students are provided with worked examples. Teachers can use the inquiry as a teaching tool and to provide similar equations for students to work through and explain their findings. Resources include a prompt sheet and PowerPoint presentation.
