• 1. QUARTER 1: REAL NUMBER SYSTEM, TOPIC: SCIENTIFIC NOTATION TIME FRAME: 5 DAYS MEASUREMENT AND SCIENTIFIC NOTATION STAGE 1 CONTENT STANDARD: PERFORMANCE STANDARD: The learner demonstrates understanding of the key concepts of scientific The learner formulates real-life problems involving scientific notation and solves notation. these using a variety of strategies. ESSENTIAL UNDERSTANDING(S): ESSENTIAL QUESTION(S): Big and small quantities can be expressed conveniently in scientific notation. Why are measures of certain quantities expressed in scientific notation? How? PRIOR KNOWLEDGE: TRANSFER GOAL(S): Possible Misunderstandings/Anticipated Misconceptions. Use scientific notation in solving problems in real-life situation. Some misconceptions of students may include: a. not all numbers can be expressed in scientific notation. Astronomy b. all big numbers are difficult to express in scientific notation. c. steps are needed to convert numbers in scientific notation. d. it is difficult to solve problems involving scientific notation. e. there are no uses of scientific notation in real life situation. THE LEARNER WILL KNOW: THE LEARNER WILL BE ABLE TO: a. numbers that are expressed in scientific notation. a. express numbers in scientific notation and vice-versa. b. real-life measures where scientific notation is applied. b. solve real-life problems involving scientific notation. c. the application of scientific notation to different disciplines. c. cite real-life situation where scientific notation is applied. d. formulate and solve real-life problems involving scientific notation. STAGE 2 Product or Performance Task: Evidence at the level of understanding Evidence at the level of performance Learner should be able to demonstrate understanding Assessment of problems formulated based on the You are an architect employed in the museum. Your of the scientific notation using the six facets of following suggested criteria: goal is to design a model of solar system. You were understanding: asked to construct a scale model including the &#xF0FC; real-life problems distance of each planet in the solar system using Explaining: How big and small quantities are &#xF0FC; problems involve real numbers using units in short distances. Your purpose is to create a expressed in scientific notation. scientific notation scale model of the solar system. The audiences are Criteria: &#xF0FC; problems are solved using a variety of the owner and visitors of the museum that will Thorough strategies
• 2. scrutinize your suggestions. Scientific is very useful Accurate Tools: Rubrics for assessment of problems in the field of astronomy. Most distances of the Justified formulated and solved. planets to the sun involved very large numbers, that&#x2019;s why they need to use a system to express these Interpreting meaning of scientific notation by large numbers into simple ones. considering the size of atom, distances of planets, etc. Criteria: Illustrative Meaningful Justified Applying a variety of techniques in posing and solving daily life problems involving very large or very small numbers expressed in scientific notation. Criteria: Appropriate Practical Accurate Manifesting self-knowledge by showing the usefulness of scientific notation in solving a problem. Criteria Reflective Responsive Showing empathy to persons who encounter difficulties in expressing big and small quantities. Criteria
