Prime vs. Composite

Prime Factorization

Using Prime Factorization to Simplify Fractions

Day One: Factor Pairs to determine if Prime or Composite

1. Begin by discussing vocabulary of factors and products (slide 2).

2. Slide 2: Use

It is possible that the game will not immediately appear. You might get this screen. It will look as if the game is not loading.

Click on the Related Resources tab. This will bring up Factor Findings.

Click on Factor Findings. You will see the following screen.

You will now need to click on the back arrow.

The game should now appear.

The teacher will demonstrate making arrays on the above website. Teachers will need to use the “Choose your own number.” option. Teacher demonstrates how to draw arrays on the grid by clicking and dragging to make arrays. Once the array has been made, the fact can be typed in the right hand side of the screen and then click on the check mark to see if correct. If an incorrect fact is entered, the program will not allow it to stay on the screen. Show students that 2 x 3 is the same as 3 x 2, etc. Students will independently find the factors for the numbers 1 – 30 and record them on the Factors Record Sheet.

3. Once the factors are all recorded ask students what they notice about the factor pairs. Guide students to see that some numbers have one factor pair (example: 5 has only 1 x 5) and some numbers have multiple factor pairs (example: 6 has 1 x 6 and 2 x 3).

4. Teachers will introduce Prissy Prime and Cuddly Composites on slide 4. The Prissy Prime flamingo has only one factor pair, hence she stands on one leg. Cuddly Composite bears are friendly, and therefore have lots of factor pairs. Have students record the numbers that have only one factor pair on the left side of the page and numbers that have 2 or more factor pairs on the right side of the page. Fill in the titles of Prissy Prime and Cuddly Composite.

Day Two: Prime Factorization

  1. Smart board Slide 2 - My Trip to Alaska: Teacher will tell the attached story as if it were true. You can use slide 2 to have students retell the story.
  2. Using the record sheet from day one, have students use highlighters to color in the prime numbers on the chart. (Slide 3) Review the meaning of prime and composite by answering the questions on the SmartBoard - slide 3.

3. Slide 4 – Click on the world icon to start the lesson

4. Teachers will need to click on the green button labeled “Step by Step” to start the video. The “Next” and “Show Me” button will also need to be used to advance through the video. “Next” is used to move to the next step and “Show Me” is used to show the work on the screen. The button to be pushed next will be flashing.

  1. Slides 5 and 6 are guided practice and slide 7 is partner practice. Paper copies of the problems are found in MATH_4_A_DAY 2 PRIME FACTORIZATION PROBLEMS 2015_RES
  2. Slide 8: Prime numbers are the basic building blocks of other numbers.

Factor trees help us break down composite numbers.

A composite number has more than 1 set of factors.

Day Three: More Prime Factorization

  1. Slide 2: Review what a prime number is and click on the link to connect to hearing Prissy Prime’s phone number.
  2. Slides 3 and 4: Review composite numbers and how 1 is neither prime nor composite.
  3. Slides 5 and 6: Review factoring and prime factorization
  4. Slides 7 and 8: Guided Practice (These problems are found on the worksheet.)
  5. Slides 9 and 10: Partner Practice (These problems are found on the worksheet.)
  6. Slides 11 – 16: Independent Practice (These problems are found on the worksheet.)

Day Four: Prime Factorization Cover UP

Directions are on first slide of the PowerPoint.

Day Five: See MATH_4_A_DAY 5 SIMPLIFYING FRACTIONS WITH PRIME FACTORIZATION TEACHER NOTES 2015_RES

Day Six: Simply Fractions Game

Directions given on the cover sheet of the game. MATH_4_A_DAY 6 SIMPLY FRACTIONS GAME 2015_RES

Day Seven: See MATH_4_A_DAY 7 ADDING AND SUBTRACTING LIKE DENOMINATORS LESSON PLAN 2015_RES

Students will be using pattern blocks to:

  • Add and subtract fractions with like denominators
  • Subtract fractions from whole numbers using decomposing fraction skills
  • Simplify to lowest terms.

Day Eight: Addition and Subtraction with Like Denominators Practice

MATH_4_A_DAY 8 SPINNER ADD SUBTRACT FUN 2015_RES

MATH_4_A_DAY 8 ADD SUBTRACT SIMPLIFY TASK CARDS 2015_RES (Direction page given)

Students will draw a task card, solve the problem and then travel to the given location in the room to check their answer.
