  1. Mathematics By Matthew Lepak

  2. Basic Math and numbers • Grade level 5th Grade • Content area: Math • Academic Standards: Students will learn the basics of math and then they will grow into trickier problems • Students will get a refresher on basic math like multiplication, subtraction, addition, and subtraction. They will also apply it to multistep problems and decimal numbers. They will also learn square roots and numbers raised to a power.

  4. Addition • Addition is adding numbers together to get a bigger number • Ex 2+2=4 • 30+10=40 • 50+50+50=100

  5. Subtraction • Subtraction is subtracting numbers to get a smaller number • Ex 2-1=1 • 25-5=20

  6. Multiplication • Multiplication is multiplying numbers together to get a bigger number • Ex 2x3=6 • 6x10=60

  7. Advanced Multiplication • There are formulas that involve more multiplication • Ex circumference of a circle: D x 3.14 • Pi=3.14 and D=diameter • Ex 2x3.14=6.28 • Area of a triangle: BxHx1/2 • B=base H=height

  8. Lets do a problem • Base of a triangle is 5 and the Height is 10. Find the Area. • Answer: 25

  9. Division • Division is dividing numbers • 4/2=2 • 10/2=5 • 36/4=9

  10. Fractions • Fractions are non-whole numbers aka less than 1 but not 0 • Ex ½ • ¾ • 28/30 • 1/100

  11. Decimal Numbers • Decimal numbers are also fraction, but they can be irrational or greater than 1 • Ex 5.5 • 0.3333333333 (1/3) • 0.48394785893839484555343 (irrational number) • 3.14

  12. More Decimals • 0.1 one tenth • 0.01 one hundredth • 0.001 one thousandth

  13. Multiplying big numbers • There are big numbers that can be multiplied too • Ex • 15x3=45 • 100x30=3000

  14. Numbers raised to a power aka exponets • Numbers raised to a power is how many times a number is multiplied by itself • Ex 10^2=100 10x10 • 2^5=32 2x2x2x2x2

  15. A number squared • Any number raised to the second power • 2^2=4 2x2 • 5^2=25 5x5

  16. Shapes that uses raising powers • Area of a circle: 3.14xR^2 • Pi=3.14 R=radius • Ex 3.14X2^2 • Answer: 39.44

  17. Lets do another problem • Find the area of a circle with a radius of 5 round your answers to the nearest hundredth • Answer: 246.49

  18. A number cubed • A number cubed is any number raised to the third power • Ex 3^3=27 • 5^3= 125

  19. Square root • A number that is multiplied by itself to get a number • Square root of 49 is 7 • Square root of 9 is 3
