This math chapter workbook on "Mass" helps students understand and compare the weights of different objects. Workbook problems include scenarios where students compare the weight of everyday objects. For example, a problem might present images of an apple and a watermelon, asking the student to circle which is heavier. To solve this, students can use visual cues or prior knowledge about these fruits' size and typical weight. Problems also ask students to order objects by mass, such as lining up a pencil, an eraser, and a notebook from lightest to heaviest.
