Arlo creates a pattern starting at the number 4. He uses the rule: add 4. Write the first 6 terms in the pattern.
4, 8, 12, 16, 20, 24
List the factors of 27 and state whether it is PRIME or COMPOSITE
1, 3, 9, 27
148 / 4 =
37
What is the formula we use to find the perimeter of a rectangle?
Length + Length + Width + Width
OR
(2 x Length) + (2 x Width)
Liz starts at the number 3. She creates a pattern using the rule: Add 3. Complete the first six terms in Liz's pattern.
Will the 80th term in Liz's pattern be even or odd? Explain how you know.
3, 6, 9, 12, 15, 18
The 80th term will be even. All even terms are even numbers, and 80 is an even term.
Which numbers are multiples of 6? Choose the 3 correct answers.
2
3
12
9
120
Which expression can be used to find 252 / 3?
a. (24 / 3) + (12 / 3)
b. (240 / 3) + (12 / 3)
c. (250 / 3) + (12 / 3)
d. (252 / 2) + (252 / 1)
B. (240 / 3) + (12 / 3)
If the length of a rectangle is 20 ft. and the width is 8 ft., what is the area and perimeter of the rectangle? LABEL CORRECTLY
Perimeter= 8 + 8 + 20 + 20 = 56 feet
Input: 1, 2, 3, 4, 5
Output: 9, ?, 27, ?, ?
Fill in the missing numbers and write the pattern.
Output: 18, 36, 45
Multiply the input by 9
Is 78 a multiple of 6? Explain why or why not.
Yes.
6x13=78
Draw an area model to solve 7 x 23
7 x 20 = 140
7 x 3 = 21
140 + 21 = 161
A rectangle has a length of 15in and a width of 5in. What is the area and perimeter of the rectangle? LABEL CORRECTLY
Area= 5x15= 75 square inches
Perimeter = 5 + 5 + 15 + 15 = 40 inches
Fill in the missing numbers and write the pattern.
Input: 12, 16, 20, 40
Output: 3, ?, 5, ?
4, 10
Divide the input by 4
Define PRIME and COMPOSITE using math terms. Give an example of a prime number and a composite number.
A prime number only has two factors- 1 and itself. For example, 3.
A composite number has more than two factors. For example, 8.
Pablo multiplies 8 x 14 using the distributive property. His work is shown:
8 x 14 = 8 x (1+4)
=(8 x 1) + (8 x 4)
=(8 + 32)
= 40
Explain Pablo's mistake and find the correct product.
Pablo didn't break apart 14 correctly. The value of the 1 is 10.
8 x 14 = 8 x (10 + 4)
= (8 x 10) + (8 x 4)
= (80 + 32)
= 112
The area of a rectangle is 90 square feet.
The width is 6 feet.
What is the length?
15 feet
The shape pattern is as follows:
Triangle, Square, Rectangle, Triangle, Square, Rectangle
If the pattern continues, what shape will be the 10th term?
What shape will be the 54th term?
10th- Triangle
54th- Rectangle
Since 3 is a factor of 54 and there are 3 terms in the pattern, it will be the last term which is a rectangle.
