Three detailed lessons with interactive applets. Illuminations

Lesson 1 - Balancing Shapes: Students will balance shapes on the pan balance applet to study equality, essential to understanding algebra. Equivalent relationships will be recognized when the pans balance, demonstrating the properties of equality.

Lesson 2 - Balancing Algebraic Understanding: Using a balance in the classroom is a first step to algebraic understanding. Use this pan balance (numbers) applet to practice the order of operations in simplifying numerical expressions and to demonstrate the conventions of using algebraic logic in simplifying expressions.

Lesson3 - Algebra in Balance: Students use the Balance Pans - Expressions Tool to explore algebraic expressions. They determine if algebraic expressions are equal. They balance pans to solve a system of equations and use graphing to find the solutions to a system of equations.[[http://illuminations.nctm.org/LessonDetail.aspx?id=L646|]]

Bungee Jumping Barbie

It has kids doing an investigation (bungee jumping a barbie doll), plotting data in scatter box plot and then generating a line of best fit. The distance that the Barbie jumps ends up to be directly proportional to the number of rubber bands -linear function. The lesson plan is set up having them collect data and plot on paper the old fashion way, but they could create a simple excel spreadsheet to do this. http://illuminations.nctm.org/LessonDetail.aspx?id=L646

Exploring Linear Data:

Students model linear data in a variety of settings that range from car repair costs to sports to medicine. Students work to construct scatterplots, interpret data points and trends, and investigate the notion of line of best fit. http://illuminations.nctm.org/LessonDetail.aspx?id=L298
