Lesson 1: Patterning Basics
Patterns Vocabulary
Lesson 2: Predict Using Patterns
Two ways to predict Number of Dots for Square 9
Use A Number Pattern RuleNumber Pattern Rule: Square Number multiply by 4 equals the number of dots on the perimeter.
(Square Number X 4 = Number of dots) So,based on this rule, Square 9 will have 36 dots on the perimeter because: 9 x 4 = 36. |

Lesson 4: Solving Equations with Addition
Use the sum to subtract the unknown addend.
Question: 19 + X = 23 Think: (23 - 19 = 4)
Answer: So, X is 4 Check: 19 + 4 = 23
Question: 19 + X = 23 Think: (23 - 19 = 4)
Answer: So, X is 4 Check: 19 + 4 = 23
Lesson 5: Solving Equations with Multiplication
The product divide by the known factor.
Question: 9 x A = 63 Think: (63 ÷ 9 = 7)
Answer: So, A is 7. Check: 9 x 7 = 63
Answer: So, A is 7. Check: 9 x 7 = 63
Lesson 6: Solving Equations with Subtraction
Unknown Minuend (first number)
Add subtrahend and difference together.
Question: X - 24 = 12 Think: (24 + 12 = 36)
Answer: So, X is 36 Check: 36 - 24 = 12
Unknown Minuend (first number)
Add subtrahend and difference together.
Question: X - 24 = 12 Think: (24 + 12 = 36)
Answer: So, X is 36 Check: 36 - 24 = 12
Lesson 7: Solving Equations with Division
Unknown Dividend (first number)
Multiply divisor by quotient to get the answer.
Question: X ÷ 8 = 4 Think: (8 x 4 = X)
Answer: So, X is 32. Check: 32 ÷ 8 = 4
Unknown Divisor (second number)
Dividend divide by quotient to get the answer.
Question: 44 ÷ X = 11 Think: (44 ÷ 11 = X)
Answer: So, X is 4. Check: 44 ÷ 4 = 11
