Weight and volume - Weight and mass problems - Starter

In a Year 1 mathematics lesson, students delve into the concepts of weight and mass through engaging problems designed to enhance their understanding and fluency in these topics. The lesson is part of the Spring Term's curriculum, specifically scheduled for Week 10, Day 5. One of the starter activities, named 'Fluent in Four - Revision', challenges the children to perform basic arithmetic operations such as subtraction and addition. For instance, they solve the equation "eleven minus eight" to find the answer, which is three, and "nine plus nine" to reach eighteen.

Another key part of the lesson involves vocabulary related to comparing weights. Students are prompted to use the words 'heavier', 'equal', or 'lighter' to describe the relationship between the weight of two objects, such as a bag and a car. Additionally, they are tasked with counting objects, like tomatoes, to practice their addition skills. The lesson also includes an exercise where students must sequence groups of numbers from the greatest to the least, further reinforcing their number sense and understanding of numerical order. This structured approach allows for a clear and progressive development of essential mathematical skills in young learners.
