Mass, Capacity, Temperature - Measure mass g - Presentation

In the fourth lesson of a series on measurement, students are introduced to the concept of measuring mass in grams. The lesson begins with a discussion on the standard units of measurement for mass, prompting students to think about the units they are already familiar with. The interactive presentation includes a variety of activities that encourage students to apply their understanding of mass measurement. In the first activity, they are presented with a balance scale holding 5 gram weights and asked to determine the mass of a teddy bear. This practical approach helps students visualise and comprehend the concept of mass and its measurement.

Moving through the lesson, the students engage in further practical exercises, such as estimating the mass of a ball of wool and a gingerbread man using 10 gram and 5 gram weights. The activities are designed to reinforce the students' ability to measure and compare the mass of different objects. In subsequent tasks, students are asked to read scales to determine the mass of items like cookies and toys, and to order objects from heaviest to lightest, enhancing their reasoning skills. The lesson also includes reasoning challenges where students must use their knowledge to explain why one object is heavier than another, further developing their critical thinking and understanding of mass measurement.
