Addition and subtraction - Add and subtract 100s word problems - Worksheet

Designed to enhance the mental arithmetic skills of Year 6 students, this worksheet focuses on the addition and subtraction of hundreds. The National Curriculum objective covered in this lesson is to mentally add and subtract numbers, including three-digit numbers with ones, tens, and hundreds. To assist with learning, differentiated worksheets and teaching slides are provided as resources. Students are encouraged to explore the use of different strategies beyond the column method, as the lesson emphasises that the ones and tens places remain unaffected when adding or subtracting hundreds. Key vocabulary such as 'add', 'subtract', 'multiples', 'place value', 'column method', 'effective', and 'bar model' are used throughout the lesson.

The worksheet presents a variety of one-step and two-step word problems that require students to add or subtract hundreds. These problems are set in real-life contexts, such as calculating savings, comparing amounts, and determining distances. For instance, students are asked to figure out how much money Mark has saved if Tracy has saved £350, which is £100 more than Mark. In another problem, they must determine how many counters Henry has if Julia has 250 counters and Henry has 200 more. The worksheet also includes reasoning and problem-solving sections where students must complete scenarios to match given bar models, encouraging them to apply their understanding of place value and the addition and subtraction of hundreds in various situations.
