Measurement Length and Perimeter - Subtract Lengths - Starter

In a mathematics exercise aimed at Year 4 students during Autumn Term's eighth week on the fifth day, they are challenged with various problems to enhance their understanding of measurement and subtraction of lengths. One of the tasks involves calculating the combined length of two wooden boards that John has purchased. The first board measures 28 cm and 25 mm, while the second board is 37 cm and 16 mm long. Students must use their knowledge of length units and addition to determine the total length of the boards together. The answer to this particular problem is not provided within the context of the exercise, requiring the students to perform the calculations independently.

Additionally, the worksheet presents a scenario comparing the volume of water held by two individuals. Leanna has three bottles, each containing 300 ml of water, while Tia possesses a single bottle with 1 litre of water. The question posed is who has more water, and students are encouraged to prove their answer. In this case, the answer is Tia, as three bottles of 300 ml equal 900 ml, which is less than Tia's 1 litre. The exercise also includes a schedule of fighting sports training sessions throughout the week, asking students to count how many days are free from boxing. This problem helps students to interpret data from a table and apply their counting skills. The answer to how many days are free from boxing is not explicitly provided, leaving students to figure it out themselves.
