Topic: Number, Money, and Measure - Rounding

Desired Outcome: I can use my knowledge of rounding to routinely estimate the answer to a problem then, after calculating, decide if my answer is reasonable, sharing my solution with others.

Level: Second Level (Scottish Curriculum)

Focus: Rounding

Week 1: - Introduction to rounding: Understanding the concept of rounding numbers to the nearest whole number, 10, 100, etc. - Exploring real-life scenarios where rounding is used, such as estimating the number of people in a crowd or the cost of items in a store. - Practice rounding numbers to the nearest whole number and discuss the reasoning behind the chosen rounding rule.

Week 2: - Rounding to the nearest 10: Introduce the concept of rounding numbers to the nearest 10. - Engage students in various activities and games to practice rounding numbers to the nearest 10. - Discuss the importance of estimating and checking the reasonableness of the rounded answer.

Week 3: - Rounding to the nearest 100: Extend the concept of rounding to the nearest 100. - Engage students in practical activities involving larger numbers, such as estimating the weight of objects or the length of a line. - Practice rounding numbers to the nearest 100 and discuss the significance of estimating and checking the reasonableness of the answer.

Week 4: - Rounding to the nearest decimal place: Introduce the concept of rounding numbers to the nearest decimal place. - Engage students in real-life scenarios involving money, such as estimating the cost of items or calculating change. - Practice rounding numbers to the nearest decimal place and discuss the importance of estimating and checking the reasonableness of the answer.

Week 5: - Rounding in problem-solving: Apply rounding skills to solve word problems and mathematical puzzles. - Encourage students to estimate the answer using rounding, calculate the exact answer, and then compare the two to determine if the rounded estimate was reasonable. - Share and discuss solutions with peers, explaining the reasoning behind the chosen rounding rule and the decision on the reasonableness of the answer.

Week 6: - Consolidation and assessment: Review rounding concepts and skills covered throughout the topic. - Provide opportunities for students to apply their knowledge and skills in a variety of problem-solving tasks. - Assess students’ ability to estimate, calculate, and determine the reasonableness of their answers using rounding.

Note: The above topic plan is a general outline and can be adapted and modified based on the specific needs and pace of the students. It is important to provide ample opportunities for practice, discussion, and reflection to ensure a deep understanding of rounding and its application in real-life situations.
