Addition and subtraction - Mixed addition and subtraction - Worksheet

The worksheet provides a series of engaging activities to help Year 6 students master mixed addition and subtraction problems. According to the National Curriculum objective, the exercises are designed to solve problems using concrete objects, pictorial representations, and numerical calculations. Students learn to add three 1-digit numbers and tackle various word problems that incorporate everyday scenarios, such as counting pears and counters. The resources needed for the lesson include teaching slides and worksheets, and the vocabulary focuses on terms like 'add', 'subtract', 'word problem', 'bar model', and 'number sentence'. Key questions prompt students to analyze the information given and determine whether to use addition or subtraction to solve the problems.

The worksheet activities range from straightforward calculations to more challenging reasoning and problem-solving tasks. In the initial exercises, students are given visual aids such as bar models with some numbers filled in to help them complete the calculations. As the difficulty increases, children are required to draw their own bars to work out the answers. For example, one problem asks how many pears Malachi and Leanna have altogether, starting with Malachi's 4 pears and noting that Leanna has twice as many. The worksheet guides students through the process of drawing bar models, setting up number sentences, and performing the calculations to arrive at the correct total. The tasks are designed to promote fluency, precision, and a deeper understanding of mixed addition and subtraction in a variety of contexts.
