Mathematics - 6th Grade

• Math 6 - Act. 06: Two-Step Equations
  Students will work through Two-Step Equations using algebra tiles, drawing pictures, and writing the step-by-step process.
• Math 6 - Act. 07: Evaluating Expressions Using Tiles
  Students will use algebra tiles to help them evaluate algebraic expressions.
• Pyramid Equality
  Students will learn about the concept of equality by balancing equations and using a pyramid.
• The New Texas Two-Step
  This activity gives a fun introduction to two-step equations.

• Distance, Speed and Time Relationships #1
  Students will examine and compare time versus distance relationships, and represent change over time as seen using a single runner along a line and review results plotted along a graph. This activity helps students identify, describe and compare situations with constant or varying rates of change.
• Interactive Pan Balance
  Students can use this interactive pan balance to help understand that equality is a relationship, not an operation.
• The Next Billion
  In 1999 the world population passed the 6 billion mark. In this lesson, students predict when it will reach 7 billion. To do so, they use an online counter that simulates the changing world population. They time the counter to find how long it takes for the population to increase by, say, 50 or 100 people. They use that measurement to predict how long it would take for the population to increase by 1 billion. Students discuss the reliability of their predictions, compare them to past trends, and discuss social factors that can affect population growth.
