Lesson Plans

Rounding Decimal Numbers - Lesson #3:

This is the final lesson in the Rounding Decimal Numbers Unit and will bring together the mathematical concepts in lesson 1 and 2. This lesson then bridges the computer science coding and mathematical thought process together as students dissect code that rounds decimal numbers as well as building their own code to make rounding an automated process.

Type: Lesson Plan

Rounding Decimal Numbers - Lesson #1:

This is lesson 1 of 3 in the Rounding Decimal Numbers unit. This lesson connects decimal place value names with exponential powers of ten. Through the inquiry based lesson, students will discover that there is a mathematical pattern they can use when performing multiplication and division using the powers of ten on a multi-digit decimal number.

Type: Lesson Plan

Rounding Decimal Numbers - Lesson #2:

This is lesson 2 of 3 in the Rounding Decimal Numbers unit. This lesson introduces Traditional Rounding method to determine an estimated value rounded to a specific place value. This lesson bridges the concepts of fractions to decimals and powers of ten as well expanded notation to rounding methods.

This lesson uses flowchart model to describe the method in which the rounding is performed. Rounded numbers are verified using a Scratch activity in this lesson.

The Coasta with the Mosta:

Students will create an exciting and thrilling roller coaster model. Students will use their knowledge of forces to build a model of a roller coaster using foam insulation and a marble.

What happens when you multiply by powers of 10?:

This lesson shows patterns when multiplying a whole number by powers of 10 through a hands-on conceptual approach that then leads into the procedure of multiplying numbers by a power of 10 and writing exponents using the base of 10.

This is intended to be an introductory lesson to the powers of ten in an exponent form. The concepts in this lesson will be a precursor to evaluating expressions using exponents and eventually scientific notation.

X-treme Roller Coasters:

This MEA asks students to assist Ms. Joy Ride who is creating a virtual TV series about extreme roller coasters. They work together to determine which roller coaster is most extreme and should be featured in the first episode. Students are presented with research of five extreme roller coasters and they must use their math skills to convert units of measurements while learning about force and motion.

Seeking Patterns Using Base 10 and Powers of 10:

This lesson focuses on the exploration of patterns in the number of zeros of the product, when multiplying a number by powers of 10. It also uses whole-number exponents to denote powers of 10.

Patterns divided by a power of ten should be done in a subsequent lesson, once the students have the basic understanding of multiplying base ten by exponents.

Patterns using decimals should be done in a subsequent lesson, once the students have the basic understanding using whole numbers.

Intro to Multiplying Decimals by 10, 100, 1000:

In this lesson, students are introduced to multiplying decimals by 10, 100, and 1000, in which students begin by creatively solving word problems. Students will analyze the number sentences used to solve the word problems, looking for and recording patterns and discovering that each place value has a value ten times as much as the place to its right, which is why each time a number is multiplied by 10, the digits move one place to the left.
