Add and subtract with written methods worksheet

The worksheet from KS2Gems, aimed at enhancing the arithmetic skills of Key Stage 2 pupils, outlines a series of objectives and activities focused on mastering formal written methods for adding and subtracting numbers with up to four digits. The main objective is for students to become proficient in columnar addition and subtraction, a fundamental aspect of their mathematical development. The worksheet is structured to provide a step-by-step approach to learning, with each activity designed to reinforce the pupils' understanding and application of these methods.

Activity 1 kicks off with a hands-on task where children use a variety of digit cards to create and solve their own addition and subtraction problems using the column method. They are encouraged to check their work by having their partner perform the inverse operation. In Activity 2, students are challenged to use digit cards to form two 4-digit numbers that meet specific criteria, such as creating the largest possible total or a multiple of 5. This activity not only practices addition but also encourages strategic thinking. Activity 3 involves analysing both correct and incorrect calculations to identify and correct errors, while Activity 4 delves into patterns and relationships within numbers by reversing digits and exploring the effects on the results of addition and subtraction. Through these engaging exercises, students are expected to develop a deeper understanding of numerical operations and their properties.
