Multiplication and Division - Multiply by 100 - Worksheet

The "Multiply by 100" worksheet is an educational resource aimed at enhancing students' fluency and precision in multiplication, specifically focusing on multiplying numbers by 100. The National Curriculum objective for this lesson is to use place value knowledge, along with known and derived facts, to multiply and divide mentally. To facilitate this learning, the worksheet provides differentiated sheets, teaching slides, and Base 10 blocks as resources. Students are encouraged to use place value counters and Base 10 to explore the changes in digit values during multiplication, helping them to discover rules and eventually move away from concrete representations to mental calculations.

The worksheet is designed to help students differentiate between multiplying by 10 and 100 using both one-digit and two-digit numbers. Through a series of calculations and comparison exercises, students can observe the effect of multiplying by 100 on a number's place value. The exercises also include real-world applications, such as converting metres to centimetres, where students must check the accuracy of conversions and explain any errors. This practical approach ensures that students not only learn the mathematical concept but also understand its relevance and application in everyday situations. The worksheet incorporates reasoning and problem-solving questions, challenging students to find the length of missing sides in geometric shapes and to evaluate incorrect representations of multiplication, further solidifying their understanding of the concept.
