1
An Array a Day Mrs. Amatangelo

2
A ray is what you learn about in geometry. This is a ray. A B This is NOT an ARRAY. Next

3
A ray gun. A stingray. A ray of sunshine. These are rays: They are NOT ARRAYS. Ray from Ghostbusters An X-ray Next

4
An is when you make rows and columns. ARRAY Next

5
Arrays are all around you. Next

6

8
Draw the array and label its dimensions.arraylabeldimensions An array with the dimensions of 6 by 2 would look like this: To label the dimensions, write a 2 to show 2 columns, and a 6 to show 6 rows. 2 6 or for a 2 by 6, like this: Next

9
An is when you make rows and columns. ARRAY Back

10
Dimensions means how many rows and how many columns Back

11
Label means to write the number that shows how many are in each row and column. Back

12
Write a multiplication sentence: There are 6 rows of 2 so the multiplication sentence is: 6 * 2 = 12 2 6 Next

13
What does it mean? The multiplication sentence 6 * 2 = 12 means there are 6 rows with 2 in each row. 2 6 Next

14
Write a division sentence. 12 / 6 = 2 2 6 Next

15
What does it mean? Take 12 squares and put them into 6 groups with 2 in each group. 2 6 Next

16
What is the area? The area is: how many squares are inside the shape. 2 6 How much carpet would I need if I covered the floor with carpet instead? How many tiles do I need to cover a floor? Next

17
What is the area? There are 12 squares inside the shape, so the area is 12 squares. 2 6 Next

18
What is the area? To find the area, multiply the number of rows by the number of columns. 6 * 2 = 12 2 6 Next

19
What is the perimeter? The perimeter is how many units surround the shape. 2 66 2 Next

20
What is the perimeter? Its like the fence that goes around the outside of the shape. 2 66 2 Next

21
What is the perimeter? The question, What is the perimeter? is asking, How long is the fence that goes around the outside of the shape? 2 66 2 Next

22
What is the perimeter? 2 66 2 This fence is 6 squares long and 2 squares wide, with 6 more squares long, and 2 more feet wide. Next

23
What is the perimeter? To find the perimeter, add all the lengths and all the widths of the sides. 6+2+6+2=16 The perimeter is 16 2 66 2 Next

24
ListList all the factors of the area.factors 1, 2, 3, 4, 6, 12 are the factors of the area 12, because: 1 * 12 =12 2 * 6 = 12 3* 4 = 12 Next

25
List List means to write as many as you can think of. Back

26
FactorsFactors = the numbers you multiply to get a productproduct Back

27
ProductProduct = the answer you get when you multiply Back

28
List all the factors of the area. 1 and 12 are factors of the area 12, because: 1 * 12 = 12 12 1 Next

29
List all the factors of the area. 3 and 4 are the factors of the area 12, because: 3 * 4 = 12 4 3 Next

30
List all the factors of the area. 2 and 6 are factors of the area 12, because: 2 * 6 Next

31
List all the factors of the area. The factors are the same numbers you used to find the area. (length * width = area) Next

32
Is the area prime or composite?primecomposite PrimePrime = the area has only two factors: 1 and itself Composite Composite = the area has more than 2 factors Next

33
Prime 1 11 1 A shape with an area of 11 is prime. The only numbers you can multiply to get 11 are 1 and 11. 1x11=11 Next

34
Some other prime arrays are: 1 7 3 2 1 1 1 13 5 1 Back

35
Composite A shape with the area of 12 is composite because 12 has more than 2 factors. Next

36
12 1 2 6 4 3 3 4 6 2 1 Back

37
Repeated Addition 2+2+2+2+2+2=12 + ++++ Next

38
Draw additional arrays with the same area and label their dimensions.additionallabel dimensions Next

39
12 1 2 6 4 3 3 4 6 2 1 Next

40
Additional: Additional: more of the same thing Label: Label: write the numbers to show what it means Dimensions: Dimensions: the size how big it is the length and the width Next

41
So what? How large of an area do we need for every student to sit at a desk? How many 25 student classes will fit in an area the size of the floor in the multi-purpose room? How much newspaper do I need to cover an area the size of the ceramics table? How much paint do I need to cover an area the size of the walls in my room? If one student needs a 9 foot square area to jump rope, how large of an area would 25 students need? The swings need a mat under them. How large should the mat be to cover the area under the swings? 5 friends brought their sleeping bags to a sleepover. If every sleeping bag covers a 12 foot area, what size tent should we use? Each family member rakes the leaves from a 100 square foot area. How many family members are needed to rake a yard with a 1000 square foot area? Next
