  1. BELL WORKAlgebra Journal #8 • Write problem, solve. • 1. -4 -6 +7 -1 = • 2. write “The absolute value of -7 =7 • 3. What is the reciprocal of -18? • 4. What is the opposite of 90? • -304 - - 106= • Check your answers with your neighbor.

  2. BRAIN PUSH-UPS • How many squares?

  3. TODAY’S NOTES • CONSTANT= any number, pos. or neg. • VARIABLE= any letter in algebra • TERM= a number, letter, or both • LIKE TERM= number terms or the same letter terms • UNLIKE TERM= terms with different letters

  4. HOMEWORK ASSIGNMENT • DUE NEXT CLASS PERIOD:all work you owe me or zeroes in my gradebook.

  5. TICKET OUT THE DOOR • 18 - - 23= • -9m + 7 + +3m + 5 =

  6. BELL WORKAlgebra Journal #9 • Write problem, solve, left side journal • 1. 8m + 7 -5 -3m= • 2. 16a -4 + 7n - 3a +n = • 3. What is the reciprocal of -111? • 4. Put in order littlest to biggest • 0 -3 11 -7 19 • 5. -115 + 367 = • Check your answers with your neighbor.

  7. BRAIN PUSH-UPS • How many triangles?Puzzle 1 - How Many Squares? (Answer next) • “” • “”

  8. TODAY’S NOTESleft hand side • POS times POS = POS +8(+9)=+72 • NEG times NEG = POS -4(-5)=+20 • NEG times POS = NEG -3(+5)=-15 • WATCH YOUR SIGNS!!

  9. HOMEWORK ASSIGNMENT • DUE NEXT CLASS PERIOD: • Write 5 multiplication and 5 division problems using pos and neg numbers, for your partner to solve. • Make an answer key to check their work.

  10. TICKET OUT THE DOOR • -5 (+7)= • -18 divided by -3 = • 25 divided by -5 =

  11. BELL WORKAlgebra Journal #10 • Write problem, solve left side journal • 1. 7c - 14 - 16c + 9c +5= • 2. -6 + 5 - 5 + 11 -3 - -2= • 3. -30 divided by +6= • 4. =2(-20)= • What is the reciprocal of -99? • Check your answers with your neighbor.

  12. BRAIN PUSH-UPS How many squares do you see?

  13. TODAY’S NOTESleft side journal • EXPONENT:small number raised tells how many times to write base number • BASE: large number, multiplied by itself a certain number times. • POWER:how you read the raised number, 2 to the 3rd power.

  14. What is the meaning of 46 ? • 46 means to multiply the base 4 by itself 6 times.

  15. The meaning of the exponent: • 1.) 46 = 4•4•4•4•4•4 • 2.) 43 = 4 •4 • 4 • 3.) 41 = 4 • 4.) 40 = ?

  16. HOMEWORK ASSIGNMENT • DUE NEXT CLASS PERIOD: • Write 10 problems and solve.

  17. TICKET OUT THE DOOR

  18. BELL WORKAlgebra Journal # • Write problem, solve. • 1.Write 3 to the 3 power and solve. • 2. Write x to the fourth power. • 3. Write a base and exponent, label it. • 4. • 5.

  19. BRAIN PUSH-UPS • How many squares do you see?

  20. TODAY’S NOTES • When exponents have the same base, ADD the exponents, • w 4 times w 3 = w7 • When exponents have the same base, SUBTRACT the exponents. • M12 ÷ M4 = M8

  21. HOMEWORK ASSIGNMENT • DUE NEXT CLASS PERIOD:Create 10 exponent problems to share with your classmates. Make an answer key.

  22. TICKET OUT THE DOOR • T5 times T13 = • W6 times w7 = • B20 divided by B10 =

  23. BELL WORKAlgebra Journal # • Write problem left hand side, solve. • 1. • 2. • 3. • 4. • 5.

  24. BRAIN PUSH-UPS • yyyy u r, yyyyy u b, i c u r y+y 4 †?†

  25. TODAY’S NOTES • PERIMETER: ADD ALL SIDES OF ANY SHAPE.

  26. Perimeter • The perimeter of a closed plane figure is the length of its boundary. 8cm 10cm 7cm 8cm 15cm Perimeter = 15 + 8 + 10 + 8 + 7 = 48cm

  27. Perimeter • Square • Triangles • Rectangle b=4cm b c L= 8cm a L=6cm P = 8 + 5 + 8 + 5 P = 6 + 6 + 6 + 6 P = a + b + c P = l + b + l + b = 2(l + b) P = l + l + l + l = 4l or 4s

  28. HOMEWORK ASSIGNMENT • DUE NEXT CLASS PERIOD:Draw 5 different shapes with measurements to give to your partner. Make an answer key.
