Number 7th-8th : Concrete Foundations
Objective: Writing and Solving Equations
Students will use the cuisenaire rods to write equations containing variables. Practice combining like terms, and visualize concepts of the properties of addition. Students will begin by determining how many other combinations can be made to form a wall of a certain length. Then students will be giving a list of equations representing walls made of stone. Each equation will have a missing "stone" and students will use the rods to find out the missing "stone". Example would be: red+green+purple = blank+green+purple. After they are done students will share their results. Students will use the concept of combining like terms and replace the blanks using variables.
