Addition, Subtraction, Multiplication and Division - Inverse Operations - Starter

As part of a mathematics lesson aimed at Year 6 students, the starter activity encourages practising fluency in four key areas: addition, subtraction, multiplication, and division. The exercises include a multiplication problem where students must calculate 8 times 7 and then select the correct model representing the calculation. The lesson moves on to real-world applications, such as determining the new altitude of a plane after it descends from an initial height of 42,473 feet by 13,254 feet, with the students being tasked to perform the subtraction to find the current flying altitude.

Additionally, the lesson incorporates the interpretation of data from a line graph, which illustrates the temperature changes in a garden over time. Students are asked to read the graph to find the temperature at 6 a.m., calculate the temperature difference between 3 a.m. and 8 a.m., and determine the time when the temperature was -3°C. The tasks are designed to enhance the students' ability to analyse graphical information and to apply their understanding of inverse operations in various contexts. The lesson also includes a simple addition problem where students must add 0.01 and 0.87, further reinforcing their arithmetic skills.
