OPENING

Standard
EQ: MGSE5.OA.1 Use parentheses, brackets, or braces in numerical expressions, and evaluate expressions with these symbols.
MGSE5.NBT.2 Explain patterns in the number of zeroes of the product when multiplying a number by powers of 10, and explain patterns in the placement of the decimal point when a decimal is multiplied or divided by a power of 10. Use whole-number exponents to denote powers of 10.
Teaching exponents is a prerequisite skill that will be taught before teaching the standards above.

What is an exponent?
How do I evaluate exponents?
What happens when we multiply a whole number by powers of 10?
How can you represent the quantity of a multiple of 10?
What pattern is created when a number is multiplied by a power of 10?

Learning Target

Tuesday: I can understand and evaluate exponents by applying the meaning of the vocabulary from the word wall.
Wednesday: I can explain patterns in a product by understanding exponents and powers of ten.
Thursday: I can explain patterns in a product by understanding exponents and powers of ten.
Friday: I can understand and evaluate exponents by applying the meaning of the vocabulary from the word wall. I can explain patterns in a product by understanding exponents and powers of ten. I can explain patterns in a product by understanding exponents and powers of ten.

Activator/Vocabulary
Daily Math Review Week 1: DMR is basic review that builds through year to make sure students retain skills all year long

Vocabulary: exponent, base, power, power of ten, evaluate

Instruction/Modeling/Instructional Activity:

Tuesday: The teacher will introduce exponents to students. Use websites to introduce and show rules to exponents. Be sure to reinforce the fact that exponents are repeated multiplication.

Wednesday: The teacher will review evaluating exponents. Teachers will explain introduce multiplying by powers of ten. https://www.youtube.com/watch?v=QIZTruxt2rQ
Thursday: The teacher will review multiplying by powers of ten.
Friday: Teacher will review all concepts taught during the week.



Expectations: Instructions for the Work Session Students will be engaged in independent and small group instruction during the work session. Remind students that they are to pay close attention during review and discussions of new and old information Students will be reminded to follow classroom rules, work hard, and put forth their best effort on the review and new information
Students will be expected to focus on new strategies, ask questions, and work bell to bell. In small groups students will strive to gain better understanding of skills that they struggle with and push themselves to a higher level of thinking.

Work Session
Performance Task/Lab/Activities
Monday: First day activities, multiplication chart fill in, skills check off
Tuesday: Exponent rules, definition, examples
Wednesday: Base ten patterns, rules, examples
Thursday: Solving products with base tens, explaining patterns, task cards
Friday: Teacher will review all concepts taught during the week.
Differentiation

Wednesday Small Groups: Students will be broke into small groups based on 5 question quiz from Tuesday class over exponents. Task cards
Missing 0-1 problem (Task Card Word Problems)
Missing 2-3 problems (Task cards)
Missing 4-5 problems (works with teacher to reinforce the exponent rules and steps)

Literacy Strategy
Write the definition of exponent, base, and power.
Exponent Court: John said the answer to 32 = 6. Is he correct? Explain your reasoning using Math vocabulary.

Assessment
Monday: First Day routines: explanations of DMR
Tuesday: TOD: Solve 2ᵌ
Wednesday: TOD: Explain the difference in base and exponent
Thursday: Explain in your own words what a base ten number is
Friday: Students will take the DMR Quiz and complete a review sheet covering all concepts taught during the week.

Closing/Summarizing:
Pulling it all Together/Sharing/Feedback
Clarifying Misconceptions Students will engage in open discussion with teacher about lesson of the day. Teacher will ask questions making sure students understand the lesson and how to work the problems. Fast math game with be played on the board to quick check for understanding of the concept and check for any issues or misconceptions in the steps or process.

Homework Multiplication Facts for QUIZ Friday

Interventions for Targeted Students
Send home study paper with steps and explanation of exponents and powers of ten. Pull out group for small group to work one on one with teacher during center time.

Cross-Curriculum Ideas
Include reading and ELA into centers when practicing exponents by having word problems that have exponents in them.
