Weight and volume - Weight and mass problems - Presentation

The presentation is an educational resource aimed at teaching children about the concepts of weight and mass through a series of engaging activities. It begins with a recap of basic arithmetic problems to warm up the students' minds. The focus then shifts to mass, with questions prompting students to spell out numbers and compare the mass of different objects. The lesson is structured to gradually build understanding, starting with simple comparisons and moving towards more complex problems involving mass measurement. Students are encouraged to use fluency and reasoning to navigate through the various challenges presented in the slides.

Activities within the presentation guide the students through practical applications of measuring mass. They are shown images of scales and asked to complete sentences by filling in the mass of depicted items, such as a giraffe or a pig, and then to calculate the difference in mass between them. Further exercises involve balance scales, where students determine the mass of objects like plates and bananas by comparing them to a known quantity of blocks. The lesson also introduces problems where students deduce the mass of one object based on the combined mass of several objects. Independent work tasks and group discussions are incorporated to reinforce the learning objectives, encouraging students to think critically about how to determine mass and compare the weight of different objects.
