Learners are introduced to the basic algebraic properties then build, draw and explain area models. In this algebraic properties lesson, students work in groups to complete a worksheet then discuss what it means to be a property in algebra. Learners complete a worksheet on distributive property and combine like terms.
What can a middle schooler do in 90 minutes? He can practice using the commutative, associative and distributive properties of addition and multiplication. He can also simplify expressions using the commutative, associative and distributive properties. Now that's time well spent!
Eighth graders reinforce their skills with the order of operations and their knowledge of the algebraic properties in a game format. In this eight grade mathematics lesson, 8th graders use standard playing cards and the basic operations to create one number using four cards. Students justify their solution in written and/or oral format.
Students use logical arguments and inductive reasoning to make or disprove conjectures. After observing a teacher led demonstration, students discover that the deductive process narrows facts to a few possible conclusions. In groups, they match definitions to a corresponding property. Students create a PowerPoint of vocabulary words, draw illustrations of mathematical properties, and use a FISH diagram to illustrate information.
Help learners translate word problems into algebraic equations. They will rewrite words using symbols and evaluate algebraic expressions using real life scenarios, animation sequences, video presentations, and activities to help students engage in learning. Activity pages are included.
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.
Students examine their prior knowledge of algebra to explore geometric proof. In this proving supplementary and complementary lesson, students prove a solution to an equation using algebraic properties. Students then write their own statements to prove their logic. Students then complete a series of geometric proof problems.
Middle schoolers add, subtract, multiply, and divide rational numbers. They find the square and the cube of numbers. They create a game incorporating computation on rational numbers. Everyone works together to write and evaluate expressions. Note: the associate video is only available via purchase, but the other activities hold enough value to support the lesson without it.
Use this activity on cross-sections of three-dimensional shapes in your math class to work on algebra or geometry Common Core standards. The lesson includes a list of relevent terminology, and a step-by-step process to illustrate the concepts with styrofoam cones and two-dimensional graphs. It also provides a link to the worksheet necessary to complete the exercise.
