Middle schoolers will identify the parts of an algebraic expression by telling the number of terms in one expression. Then they will collect like terms and solve three problems. Next, they will complete a table involving three sets of algebra tile displays, evaluating each with a given value of x. In all they will solve 4 application problems. Answer key is not included.
Learners understand that algebra is a branch of mathematics that uses symbols or letters to represent unknown numbers in problems. They also understand the definition for an algebraic expression. Make sure to click on the Download the Activity bear so that you can access a top-notch task document that walks learners through the evaluation of algebraic expressions. It can be used as part of your lesson or sent home as reinforcement.
How does algebra relate to real life? High schoolers will construct and test computer chips to determine the function of each, and discuss real life applications of the Boolean Algebraic concept. Included are discussion questions, gender equity considerations, web links, a clear procedure, and all necessary worksheets. The format is a slide show.
This lesson plan is all about systems of equations and their graphs. Algebra learners create and solve systems of equation using tables and graphing. They identify the point of intersection of a system of equation, and discover what the solutions are when the lines are parallel or are the same line.
Students study exponential decay and its application to radiocarbon dating. In this exponential decay lesson, students use candy to model the time it takes for something to decay. Students also graph the data they collect and describe using an algebraic formula that gives the age of an object as a function.
Middle schoolers create a method for finding the area of a fame for a picture and then transfer their shared methods into algebraic expressions. They develop the algebraic language to communicate and solve problems effectively and use variables and symbols to write equations. Pupils use the computer to examine graphic representation of their equations.
How do you show that something is a rectangle? This activity starts with four coordinate points and asks young geometers to explain whether they create a rectangle. Knowledge from both geometry and algebra come into play here, as well as, exploring many different approaches to solve this problem; making this a good small group activity. See how many solutions your class can find!
The amount of tax and tip on a restaurant bill is a common example used in percent problems. Here, learners only know the total amount paid, and they need to figure the itemized amounts. Solutions using a ratio table, using knowledge of percents and division, or creating an algebraic expression are all explored.
Interpreting algebraic expressions is a fundamental skill in beginning algebra. This lesson approaches the task in numerous ways. First, learners assess their understanding with a short worksheet on converting between words and expressions. They then work in pairs to translate between words, symbols, tables of values, and graphic area representations of expressions. Using card sets to match representations keeps them engaged. All or part of this well-written lesson could be used to evaluate, or extend your students' understanding.
