Mass, Capacity, Temperature - Four operations with mass - Planning

In the third week of the Summer term, Year 2 students delve into the subject of mass, capacity, and temperature, with a particular focus on the four operations with mass. The National Curriculum objectives for this week include estimating and measuring mass in kilograms and grams, understanding temperature in degrees Celsius, and measuring capacity in litres and millilitres using appropriate tools. Students compare and order mass and volume, recording their findings with symbols such as greater than, less than, and equal to. Key vocabulary such as 'mass', 'weight', 'heavier', 'lighter', 'total', and 'difference' is introduced, with resources like differentiated worksheets, teaching slides, and mini whiteboards to aid learning. Interactive activities and links to online resources are provided to enhance engagement and understanding.

The lesson begins with a recap of previous learning, followed by practical activities where students calculate the total mass of objects and the difference in mass between them, using tools like base 10 and bar models. Reasoning exercises challenge students to apply their knowledge in real-world scenarios, such as determining the mass of fruit based on given information. The lesson aims to address common misconceptions and reinforce understanding through group work and independent activities. Students are encouraged to reflect on the skills they've used and what they've learned, ensuring they grasp the concept of mass and can perform basic mathematical operations with it. The lesson plan caters to different levels of student ability, from working towards expected standards to achieving greater depth in their understanding and application of mass calculations.
