Place value - Compare objects - Worksheet

In Lesson 11, titled "Comparing Objects," students in Year 6 are taught how to compare and order numbers up to 1,000. The lesson is part of a series on place value, and it encourages the development of fluency and precision in mathematical understanding. To facilitate learning, differentiated worksheets, teaching slides, and concrete manipulatives are provided as resources. The key vocabulary for the lesson includes terms such as "compare," "objects," "represent," "numbers," "greatest," and "smallest." Through the use of objects to represent numbers, students learn to apply comparative language and symbols to discern which numbers are greater or smaller. They are encouraged to use concrete manipulatives to build the numbers and then draw them pictorially. The lesson further supports vocabulary development by incorporating stem sentences, such as "_______ is greater than _______," to ensure accurate use of mathematical terms.

Throughout the lesson, students are prompted by key questions that challenge them to think critically about the comparison process. These questions include considerations about the starting point for comparison, whether to begin with hundreds, tens, or ones, and the strategies employed to determine the greater or smaller number. The lesson also addresses common misconceptions, ensuring that students understand that a right-angled triangle with the same length and perpendicular height as a rectangle will have an area half the size. By linking the area of a rectangle to that of a triangle, children are guided to correctly use the formula to calculate the area of a triangle. Differentiated activities are planned to cater to students working towards expected levels, working within them, and those capable of greater depth, offering a comprehensive approach to mastering the concept of comparing objects and understanding their numerical value.
