Objectives
This 4-week instructional unit is designed to ground and solidify middle school students’ knowledge of the numerical makeup of decimals and decimal fractions (place value, order of magnitude, significant figures, exponential properties, and scientific notation). It will be introduced in parallel with the Module 1 of the 8th Grade Eureka/EngageNY curriculum. Through varied student-centered activities such as problem sets, inquiry-based activities, comparative analysis practices, using the Standards of Mathematical Practice, and through promoting constructivism in class, students will be able to access the content material from many different learning levels. All of the topics covered in my unit will be designed around the Common Core State Standards (CCSS) as outlined in the Appendices and will follow the pacing guidelines suggested in the DCPS Scope & Sequence. This unit is composed of 8 topics: the 5 stages of place value, place value of a decimal number, order of magnitude, the Law of Exponents (also known as the product rule), and its related rules -the quotient rule for exponents, zero property of exponents, negative property of exponents, and the power rule of exponents. Three overall objectives will be used to monitor and measure student growth including:
- Know & apply the 5 stages of place value (which will be reviewed for whole numbers) to efficiently decompose a number written in decimal form.
- Understand and use the Law of Exponents for positive, zero, and negative whole number exponents.
- Apply the Law of Exponents to develop equivalent expressions using the powers of 10.
