L4 Understand How Dividing by 10 Affects Digits

Help Year 4 pupils develop a secure understanding of place value and decimals with this engaging lesson on dividing by 10. Aligned with the National Curriculum objective of finding the effect of dividing one- and two-digit numbers by 10 and identifying the value of digits in the answer as ones, tenths and hundredths, this comprehensive lesson plan provides a practical and visual approach to mastering an important mathematical concept. Through the use of place value charts, counters and structured questioning, children explore how dividing by 10 affects the value of each digit. Learners discover that when a number is divided by 10, each digit moves one place to the right, creating decimal numbers and introducing tenths in a meaningful way. The lesson builds on prior learning in place value, multiplication, division and decimals, helping pupils make strong connections between these key areas of maths. This Year 4 maths resource includes a carefully structured lesson sequence with a starter, teaching input, practical activity and plenary. Pupils use hands-on resources to model division by 10, record calculations and compare answers using mathematical symbols. By physically moving counters on place value charts, children gain a deeper understanding of how digits change value when numbers are divided, helping to strengthen conceptual understanding rather than relying on memorisation. Ideal for classroom teaching, intervention groups or home learning, the lesson also includes key questions, assessment opportunities, required resources and guidance on common misconceptions. Teachers can use this resource to identify and address errors such as incorrect digit movement, missing decimal points and misunderstandings about place value. This lesson provides an excellent foundation for future learning involving decimals, division and place value across Key Stage 2.
