MA.5.A.4.1: Use the properties of equality to solve numerical and real-world situations.

objectives
Objectives
  • Represent numbers using variable
  • Use inverse relationships
materials
Materials
  • Color Counters
  • Linking Cubes
  • Balance Scale
  • Color Tiles
  • Blank Copy Paper
  • Markers
  • Scissors
differentiation
Differentiation
  • A: Review concept of equality using linking cubes and a balance scale, placing one color cubes on one side, and a different color on the other side.
  • B: Using the 5 column method, solve a series of fractions with un-like denominators.
  • C: Using the 5 column method, solve a series of fractions with un-like denominators. There will be mixed numbers, and fractions requiring re-grouping.
  • Students will be able to move from one group to another as work is completed.

  • Review writing equations based on word problems: http://www.ixl.com/math/grade-5/write-variable-expressions
  • Review using inverse operations to solve for a variable using simple equalities:

You do: Solve the following problems alone:

Work Period
  • John has some potatoes. He buys 6 more at the store. Now he has 20 potatoes. Write an equation to determine how many potatoes John had before he went to the store. He has a recipe that uses 5 potatoes to make a bowl of mashed potato. Write an equation to determine how many bowls of mashed potato he can make with 20 potatoes.
  • Write an equation following the example from the chart. Then, write an inverse operation you can use to solve for x. Finally, solve for x.
  • Raise your hand in order to receive the next step!!!
