Addition and subtraction within 10 - Finding a part - Worksheet

The "Finding a Part" worksheet is a comprehensive tool designed to enhance the arithmetic skills of young learners, specifically focusing on addition and subtraction within the number 20. The National Curriculum objective for this lesson is to enable children to add and subtract one-digit and two-digit numbers up to 20, including zero, to understand and use number bonds and related subtraction facts within 20, and to solve one-step problems that involve these operations. This includes reading, writing, and interpreting mathematical statements with addition, subtraction, and equals signs, as well as solving problems with missing numbers.

To facilitate this learning, the worksheet provides differentiated resources, including teaching slides and practical tools such as part-whole models, cubes, and counters. The key vocabulary for this lesson includes terms like "add", "subtract", "number bonds", "counting on", "missing parts", "part-whole", "value", and "number sentence". Children will apply their understanding of number bonds by starting with a given part and counting on to find the missing part, ensuring they grasp the concept of zero's role in these equations. The worksheet is structured to guide children through the process of completing part-whole models and number sentences, with varying levels of difficulty to cater to different learning stages, from working towards fluency to achieving greater depth in reasoning and problem-solving.
