Addition and Subtraction - Estimate and Approximate - Worksheet

The worksheet titled "Estimate and Approximate" is an educational resource designed to enhance children's skills in using rounding to check answers and determine appropriate levels of accuracy in various contexts. It aligns with the National Curriculum objective that focuses on these estimation strategies. The worksheet provides differentiated activities that cater to varying levels of ability, from "Working Towards" to "Greater Depth." The teaching slides and worksheets included are resources aimed at facilitating the learning process. Key vocabulary for the lesson includes terms such as 'estimate', 'approximate', 'rounding', and 'appropriate', along with the concepts of rounding to the nearest 10, 100, or 1,000. Students are encouraged to choose the most suitable numbers for rounding to make quick and efficient estimates.

Throughout the activities, students are presented with practical problems involving money and measurements, where they need to apply their estimation skills. For example, they might be asked to estimate the total cost for a child attending an outdoor trip by rounding the cost of tickets and meals to the nearest whole number. Similarly, they must estimate the number of school dinners needed by rounding the number of boys and girls registered for meals. The worksheet also includes reasoning and problem-solving tasks where students must select the most accurate estimation for given calculations, such as summing or subtracting large numbers. This hands-on approach not only strengthens their numerical fluency but also helps them understand the real-life applications of estimation, such as budgeting or planning events.
