This lesson was created using a SMARTBoard template, and it contains numerous interactive examples of graphing inequalities with one unknown variable. The students are able to come up to the SMARTBoard in the classroom and use their fingers to drag a dot (either solid or empty) and a line that is pointed in the appropriate direction onto a number line. This gives the students a chance to get out of their seats and learn how to graph inequalities without a worksheet or problems out of the textbook. The students also learn how to add, subtract, multiply and divide when solving for the unknown term of an inequality.
Project/Presentation: Linear Equations
The project in this unit is a cooperative learning activity that requires students to work in groups of four. The students are required to create an online presentation (the class example was created with Prezi) with four different scenarios that can be represented by a linear equation. This project will give the students experience using technology to organize information, and they might possibly use their technology resources to find examples that they can use.
Students are able to use the internet when finding the meaning of the vocabulary words, along with examples of synonyms and antonyms of the words. Some students might not need to use the resource as much as others, but the option is there. The students must determine which sources give appropriate and accurate information. Also, ELL students can use this resource to find similar words in their native language so that they can use this knowledge to better understand the English meaning and spelling.
There are a few instances in the unit that require the students to find real-world examples of the mathematics they are learning in the classroom. The goal is for students to find these examples in their own lives so that they can personally relate to the material, but it is also possible to find examples of their uses online. This would require the students to find a credible source and use appropriate technology to access information.
