Place value - 1, 10, 100 more or less - Worksheet

The lesson on 'Place Value - 1, 10, 100 More or Less' is designed to enhance the numerical understanding of children by teaching them how to find 10 more or less than a given number. This builds upon the knowledge they acquired in Year 2 regarding finding one more or less. The lesson utilises differentiated worksheets, teaching slides, and practical resources such as Base 10 and Place Value Counters to aid learning. Children are encouraged to express their answers in various forms, including numerals, words, or using physical manipulatives. Key questions prompt students to consider which column changes when adding or subtracting 10 and to explore the effects of these operations on numbers like 509.

Activities range from completing simple tables to finding 10 more or less, to more complex tasks involving missing parts in a table. Students also practice writing numbers in words. As they progress, children are challenged with reasoning and problem-solving exercises. They tackle one-step and two-step problems, using their knowledge of place value to add or subtract multiples of 10 and 100. For instance, they might determine a number that is 10 more than their own number, which is also 100 less than 300. By engaging with these activities, children develop fluency, precision, and the ability to reason mathematically.
