Multiplication and division - Divide 100 into 2, 4, 5 and 10 equal parts activity - Starter

In a series of engaging mathematics activities designed for Year 3 students during the Spring Term's second week, the focus is on strengthening their multiplication and division skills. The starter activity prompts students to divide 100 into equal parts of 2, 4, 5, and 10, setting the stage for a deeper understanding of division concepts. One of the key exercises, 'Fluent in Four - Revision', challenges students to find the missing number in an addition problem where 342 plus an unknown number equals 406. This encourages mental arithmetic and problem-solving skills.

Students are also tasked with completing calculations by partitioning, a method that breaks down numbers into more manageable parts, such as tens and ones, to simplify the arithmetic process. For example, they are asked to complete a part-whole representation for the division of 24 by 2, sharing the tens and then the ones to find the answer. Additionally, the activity includes a practical application of mathematics, where students must determine the mass by combining different weights such as 70 kg, 60 kg, and 80 kg. To further develop their geometric knowledge, they are asked to identify shapes with 5 vertices. These varied and interactive tasks are designed to enhance the students' numerical fluency and understanding of basic geometric concepts.
