Presentation Transcript

  1. Unit 4 We are simplify expressions on an expression mat to determine which of them is greater. CC2: 6.1.1

  2. Unit 4 We are finding and representing solutions to one‑variable inequalities on number line graphs and recording our steps. CC2: 6.1.3

  3. Unit 4 We are solving one-variable inequalities and expressing solutions using words, graphs and symbols. CC2: 6.1.4

  4. Unit 4 We are using formal notation while simplifying expressions and solving equations. We are comparing arithmetic and algebraic methods for solving problems. CC2: 6.2.3

  5. Unit 4 We are extending and modifying the 5‑D Process by taking the variable expression and writing it as an equation. CC2: 6.2.4

  6. Unit 4 We are continuing to develop a method to define variables and write and solve equations from a context.  We are using estimation to check the reasonableness of our solutions.  CC2: 6.2.5

  7. Unit 4 We are solve equations that have infinite solutions and those with no solutions. CC2: 6.2.6

  8. Unit 4 We are learning to use multiplication to scale a quantity. We will connect finding percents of a number with multiplying by an equivalent fraction or decimal. CC2: 7.1.2

  9. Unit 4 We are learning to recognize that different multipliers find different related quantities that can be used to solve percent discount and increase problems. CC2: 7.1.3

  10. Unit 4 We are learning to solve equations with fractional coefficients and decimal coefficients. CC2: 7.1.4

  11. Unit 4 We are learning to transform equations with decimal and fractional coefficients to equivalent equations with integer coefficients. CC2: 7.1.5

  12. Unit 4 We are learning to develop an understanding of ways to transform equations with decimal and fractional coefficients to equivalent equations with integer coefficients. CC2: 7.1.6

  13. Unit 4 We are learning to develop an understanding of percent increase and decrease as scaling a quantity and will identify a multiplier related to the amount of change. CC2: 7.1.7

  14. Unit 4 We are learning to understand simple interest. CC2: 7.1.8

  15. Unit 4 We are learning to find missing information in proportions. CC2: 7.2.1

  16. Unit 4 We are learning to investigate different strategies for solving proportions. CC2: 7.2.2
