Well rounded: Use estimation and approximation to solve problems and check solutions

“Well rounded” is a lesson about how to use rounding and estimating to make numbers simpler. By the end of this topic students will be able to round whole numbers and decimal places correctly.
This lesson is appropriate for learners who need a simple presentation of this subject to complement any programme of functional maths at Level 1, and can be used with a range of groups depending on their needs and abilities.
Two files are included with this topic. The first file is a slide show presentation which can be used with a whiteboard or pc/laptop and projector, to add structure to the lesson for students. It also provides good evidence of lesson planning. The slideshow adds visual appeal and interest to engage students. The final slide is a review for students to consolidate their learning on this topic.
The second file includes a teacher answer sheet, and student score sheets to copy if needed. The lesson can be run from the presentation alone, if students make notes in their own files or on paper. The score sheet is provided as an optional extra.
