5th Grade Math Unit 6

Big Idea:

Simplify expressions using the order of operations and balance equations.

Student Expectations:

Priority TEKS

5.4(B) [Readiness] Represent and solve multi-step problems involving the four operations with whole numbers using equations with a letter standing for the unknown quantity.

5.4(F) [Readiness] Simplify numerical expressions that do not involve exponents, including up to two levels of grouping.

Focus TEKS

5.4(A) [Supporting] Identify prime and composite numbers.

5.4(E) [Supporting] Describe the meaning of parentheses and brackets in a numeric expression.

Student Learning Targets:

• I will understand and be able to describe the difference between a prime number and a composite number.
• I will use the parentheses and brackets appropriately when simplifying expressions.
• I will be able to take a situation and create an expression that matches it.
• I will apply your knowledge of the acronym PEMDAS to simplify expressions correctly.
• I will use a pan balance correctly to balance out an equation and find the unknown quantity.
• I will model equations in all four operations.
• I will solve for the unknown quantities, known as the variables.
• I will write out the steps to PEMDAS and how they help with the process of solving equations.

Essential Questions:

• How can we identify if a number is prime or composite?
• Can we get the same answer without using the order of operations, PEMDAS?
• How can we use numerical expressions to describe a situation?
• What will happen if we don’t use PEMDAS?
• How can you use a pan balance to model and solve an equation with an unknown quantity?
• How can you model and solve equations?
• How can you solve addition, subtraction, multiplication, and division equations?
• How can you represent and solve multi-step problems using equations?
