Length and Perimeter - Measure perimeter - Starter

In a mathematics resource designed for Year 3 pupils during the Spring Term, there is an exercise that combines arithmetic revision with practical measurement problems. The "Fluent in Four" section challenges students to engage in quick mental arithmetic, such as subtracting one number involving hundreds, tens, and ones from another, and adding a three-digit number to find a sum. For example, pupils must calculate the difference between 987 and 789, and then add 489 to find the total of 846. This exercise reinforces their understanding of place value and addition.

Another part of the activity focuses on understanding the concept of perimeter by asking students to determine the longest possible perimeter that can be made with three tiles, each with given dimensions. The exercise also includes a real-world application of ratios, where students must fill in the blanks to find how many peaches weigh the same as a certain number of ice creams, and vice versa. Additionally, there's a pictogram representation task that requires pupils to interpret data and identify the number of ladybirds shown. This variety of tasks not only tests their numerical skills but also helps them to apply mathematical concepts to everyday situations.
