L7 Solve Problems involving Dividing by 10 or 100

Build fluency, reasoning and problem-solving skills with this Year 4 decimals lesson on applying knowledge of dividing by 10 and 100 in practical contexts. Designed to support the National Curriculum objective of finding the effect of dividing one- and two-digit numbers by 10 and 100, this resource helps pupils use their understanding of ones, tenths and hundredths to solve meaningful mathematical problems. The lesson begins with a review of dividing by 10 and 100, allowing teachers to identify and address misconceptions before introducing problem-solving activities. Pupils explore real-life scenarios involving money and decimals, discussing which calculations are required and explaining their reasoning. Through guided examples, collaborative discussion and independent challenges, children learn how to select appropriate methods, interpret decimal answers and justify their solutions. Practical resources, including place value charts, counters and problem-solving task cards, support learners in developing a deeper understanding of decimal place value. The lesson also provides opportunities to assess reasoning skills through true-or-false challenges, encouraging pupils to analyse calculations and explain mathematical thinking. Common misconceptions, such as misunderstanding the direction digits move when dividing, misplacing decimal points or confusing tenths and hundredths, are directly addressed throughout the lesson. Ideal for mastery teaching, whole-class instruction or intervention groups, this resource strengthens pupils' confidence in applying decimal concepts to a variety of mathematical situations.
