Place value - 1,000 more and less - Starter

In a mathematics lesson focused on place value, specifically learning about 1,000 more or less, Year 4 students are presented with a variety of tasks to enhance their understanding of number manipulation. The lesson begins with a "Fluent in Four" revision exercise, where students are challenged to subtract quantities involving tens and ones, for example, subtracting 3 tens and 25 ones from 6 ones and 7 tens. As part of the Autumn Term's curriculum for Week 3, Day 2, students are required to complete a table that prompts them to explore the effects of adding or subtracting 10 from a given number, helping them to grasp the concept of place value and the changes it incurs on numbers.

Further into the lesson, students are asked to apply their understanding of place value and measurement by arranging pencils in descending order according to their lengths. The pencils belong to three children—Mark's pencil measures 21 cm 6 mm, Tom's is 162 mm, and Jack's is 219 mm. Students must convert the measurements to a common unit if necessary and then order the pencils from longest to shortest. This practical application of place value and measurement not only reinforces their numerical skills but also introduces them to real-world scenarios where such knowledge is applicable. The lesson concludes with a calculation task, where students practice their subtraction skills by solving problems such as 84 minus 52, reinforcing their arithmetic proficiency.
