Wednesday May 19


Well, we made it through the 30 year anniversary of the Mt. St. Helens eruption without a repeat performance.  Talk about a major piece of our nation's history right close to home!

Daily5:
For problems 1-3, write whether you agree with Joel's math or not.  If not, fix his error.
1.  16 - 4 x 2  =  8
2.  5 + 4 x 3 + 2  =  29
3.  3(1 + 4) / 5  =  3

4.  Place parentheses in this expression to make the equation true:
     8 x 4 - 1 / 6  =  4

5.  Mr. B spent $55 on tulips and daffodils for his wife on Mother's Day.  A bunch of tulips cost $5, and a bunch of daffodils costs $4.  He bought 12 bunches of flowers -- how many bunches of each type did he buy?

BONUS: Solve  7 x 3 - 15 / 3 + 3^2 x (5 - 2) + 8  =  ???

In Class:
  • We will practice writing expressions, then solving them.
  • We will correct the rest of pg. 23-24 homework.  You should have made corrections last night.
  • We will define some vocabulary terms.
    • variable
    • variable expression
    • evaluate
    • equation
    • solve an equation
  • We will practice using variables in expressions (use only a half-sheet):
