1. Apply at the Local Candy Shop

2. We will analyze the rules of divisibility.
I will discuss with my partner how to apply the rules of divisibility for the numbers 2, 3, 5, 7, and 11 for a friendly game of competition.
We will analyze the rules of divisibility.

3. 2 = If the number ends in a 0, 2, 4, 6, or 8 it is divisible by 2.
3 = If you add up the digits in a number and the sum is able to be divided evenly by 3. (ex. 15 => 1+5=6 and when you divide 6 by 3 you get 2)
5 = If the number ends in a 0 or a 5 it is divisible by 5.
7 (the ugly duckling)= There is no trick, you just have to know the products of 7.
11 (twins) = Any number that reflects itself (22, 33, 44, 55…) is divisible by 11.

4. Yellow/Gray = can only be found by multiplying that number by 1
White = shows you all of the factors you can use for that product/number (remember that that number can also be multiplied by 1)
Can numbers be divisible by more numbers than just 2, 3, 5, 7, and 11? How do you know this?

5. ACTIVITY TIME 5 Roll the two dice and use them to create a number
or 35
Decide which Rule of Divisibility you can use on the number
Rule of Divisibility that matches is 5 and/or 7
Color in the honeycomb with the number that fits the rule that you have chosen
The first person to fill in a row (horizontal or vertical) is the Winner Winner Chicken Dinner!! 5

6. Day in Review EXIT TICKET QUESTION: What did we do today?
We learned quick tricks to determining if a number is divisible by 2, 3, 5, 7, or 11
We analyzed a hundreds chart to learn how to read it and locate what factors a number is divisible by
We applied our new skills to an activity
Did we master today’s objective?
I will discuss with my partner how to apply the rules of divisibility for the numbers 2, 3, 5, 7, and 11 for a friendly game of competition.
EXIT TICKET QUESTION:
What two new pieces of reference material can us use to determine what factors a given number is divisible by?

7. We will identify prime and composite numbers.
I will discuss with my partner how prime and composite numbers are similar and different.
We will identify prime and composite numbers.

8. The local candy shop is wanting to start boxing their candy versus selling it by the bag.
The boxes can only be rectangular or square in shape.
There can be no empty spaces in the box (all spaces need to have a piece of candy filling them)
You need to find all of the different types of boxes that can be assembled using the given the number your boss tells you that they want in a box.

9. Yellow/Gray = Prime Numbers
White = Composite Numbers
1/Red = Is not Prime or Composite

10. Example: The boss gives you the number 6

11. The boss gives you the number 7
Example:
The boss gives you the number 7
7x1

12. Help Wanted: It’s Your Turn to Shine
Step 1: Draw a number from the bucket
Step 2: Discuss with your partner how many rectangular or square shaped candy boxes you can make with that number (lay your ideas out on paper to see if they work or not)?
Remember: You CANNOT have any empty boxes!!
Step 3: Draw your blueprints on the paper
Remember the Objective:
I will discuss with my partner how prime and composite numbers are similar and different.

13. Prime Numbers Only have 2 factors (1 and itself)
You can only build one type of box for these numbers
What is the reason for only being able to build one type of array or candy box for the number 23? 2
2x1 3
3x1 5
5x1 7
7x1 11
11x1 13
13x1 17
17x1 19
19x1 23
23x1 29
29x1 31
31x1 37
37x1 41
41x1 43
43x1 47
47x1 53
53x1 59
59x1 61
61x1 67
67x1 71
71x1 73
73x1 79
79x1 83
83x1 89
89x1 97
97x1

14. You can build more than one type box for them
What kind(s) of arrays or candy boxes can you design with the number 16?
Composite Numbers
Have more than 2 factors
You can build more than one type box for them 4 6 8 9 10 12 14 15 16 18 20 21 22 24 25 26 27 28 30 32 33 34 35 36 38 39 40 42 44 45 46 48 49 50 51 52 54 55 56 57 58 60 62 63 64 65 66 68 69 70 72 74 75 76 77 78 80 81 82 84 85 86 87 88 90 91 92 93 94 95 96 98 99
100

15. Special Note: The #1 is not prime or composite!!
It is not prime because it does not have exactly two different factors like other prime numbers, its only factor is 1 (1x1).
It is not composite because it does not have more than two factors.

16. What distinguishes a composite number from a prime number?
Prime or Composite???
What distinguishes a composite number from a prime number?

17. Way to make it through your first day of training!
