Solving Equations with Variables on Both Sides

/in /by
  1. This lesson will teach the kids how to solve equations with variables on both sides of the equation as well as showing the kids how to solve equations where they need to use the distributive property and combining like terms.

Another Dimension

/in /by

This three day lesson for Algebra I, part I students is designed to give concrete experiences in finding volume and surface area of prisms, and the volume of cylinders. Students will work with manipulatives, applets, and equations to be able to calculate of how changes in one attribute of the figure will affect surface area and volume.

Solving Inequalities

/in /by
  1. Earlier in the school year, students learned the inequality symbols and used them to compare fractions, decimals, percents, integers, etc. They have just finished a unit on equations.  The next natural step is to link these two ideas together and have them work with one-step inequalities, learning to solve them and graph their solutions. This is the second of two lessons that will address these topics.  This one will focus on solving inequalities.

Applications of Tax & Discount

/in /by
  1. In the previous lesson, students have learned what discount and sales tax are, how to calculate them, and how to calculate the resulting sale price or resulting final price. Now they will review these skills, complete a more challenging non-routine problem, and begin working on a project to show what they have learned.

Calculating Tax & Discount

/in /by
  1. Here they will learn to calculate sales tax and discount, to extend upon their knowledge of the percent proportion with consumer applications. Students should be fairly confident in working with the percent proportion by the time they get to this lesson.  It should also be a high interest lesson for them since many middle school students like to shop or go shopping with their parents.

Design Challenge Project

/in /by

Students will be able to apply their knowledge of discount and tax to re-design a room in their home on a budget, buying new items and calculating given discounts and tax.

Intro to the Coordinate Plane and its 4 Quadrants

/in /by

Students will define and then in their own words explain the following terms: x and y axis, coordinate plane, quadrant, origin, ordered pair

Students will apply their definitions as they create and label their coordinate plane.

Students will demonstrate their knowledge on a homework assignment due the next day.  The assignment is a puzzle with a coordinate plane.  In each quadrant, letters are plotted and students solve the puzzle by correctly matching the letter to its ordered pair.

Introduction of Circles/ Discovering Pi

/in /by

In this lesson, we will discuss vocabulary associated with circles (radius, diameter, circumference), which most students should be familiar with, and discuss why the formulas similar to what we used with polygons for area and perimeter won’t work with circles (circles don’t have sides, aren’t polygons).  Once that discussion is over, I will introduce Pi and ask if any students have heard of it (not the kind you eat!) and tell them it’s the “magic” number when it comes to circles.  We will then do the activity, which is the main part of today’s class.

Parts is Parts

/in , /by

Students will demonstrate a fair share by drawing pictures, making a chart, or by using manipulatives.

Students will manipulate parts of a whole and make a whole from fractional parts.

Students will demonstrate and describe equivalencies using the fraction strips.
