Length and Perimeter - Activity calculate perimeter - Starter

Master the Curriculum offers a variety of mathematical challenges designed to enhance the skills of Year 3 students in their Spring Term. On Week 10, Day 3, pupils tackle problems involving measurements and perimeters. For instance, Drew's fire engine toy is stated to be 14 cm in length, and students are asked to calculate the length of a plane that is 9 cm longer, which would be 23 cm. Additionally, they must determine the length of a car that is half the length of the 14 cm fire engine, resulting in a 7 cm measurement. The exercises also include a scenario where Malachi has an unspecified number of pence more than Leanna, prompting students to work out the difference in their amounts. Furthermore, the worksheet challenges students to select the correct calculations to determine the perimeter of a rectangle, with sides of 4 cm and 2 cm, demonstrating that adding all four sides or multiplying the sum of one set of opposite sides by two yields the same result.

On Week 10, Day 4, the focus shifts to division and problem-solving with directions. Students are asked to perform division calculations, such as dividing 168 by 3 to find the answer, which is 56. They are also given a scenario involving a map and asked to write directions to guide a person to a house, developing their spatial awareness and instruction-giving skills. The concept of perimeter is revisited with a question about the perimeter of a triangle, which is equal to that of a square, both with sides measuring 4 cm. This leads students to conclude that the perimeter of each shape is 12 cm. These activities not only reinforce basic arithmetic operations but also encourage logical thinking and the practical application of mathematical concepts in everyday contexts.
