Model Lesson

Lesson Overview
Grade Level			4th Grade
Estimated Time Needed			One 45-minute class period
Lesson Description			Students will be read the Grouchy Ladybug by Eric Carle aloud in class. The teacher will read the story to the students while students follow the elapsed time using small analog clocks provided by the teacher. Students are expected to show the accurate end time of the story using these clocks. Students will then engage in a brief discussion with the teacher on how to solve problems based on time (students are expected to explain how timelines can help solve time-based problems).      Once the story has been read, students will receive a recording sheet and a scenario. Students will record information they find from the scenario on the sheet and work to solve a question based on the scenario suing timelines as a strategy. The first question will be based on finding end time given a start time and elapsed time.    A second scenario will be given focusing on having the students find elapsed time given time intervals. Students will use timelines as a strategy to solve these problems.    Students will then focus on a we do, you do sheet which begins with a scenario in which students will solve a problem that will focus on finding both elapsed time and end time while using non-benchmark units of time.    Students will complete the lesson by finishing an exit ticket based on the lesson.
Content Area Standards			4.8 (C)  (8)  Geometry and measurement. The student applies mathematical process standards to select appropriate customary and metric units, strategies, and tools to solve problems involving measurement. The student is expected to:     (C)  solve problems that deal with measurements of length, intervals of time, liquid volumes, mass, and money using addition, subtraction, multiplication, or division as appropriate.
Technology Standards			Overhead projector
Objectives			Students will be able to solve problems that deal with the measurement of time, including solving for elapsed time and end time, using timelines.
Resources/Materials/Tools
Terms/Vocabulary			Intervals, elapsed time, start time, end time
Technology Resources			Overhead projector
Other Resources			Recording sheet, small handheld clocks, Book: The Grouchy Ladybug by Eric Carle, We Do, You Do sheet.
Lesson Procedures
	Description			Teacher Does	Student Does
Engage (Engage student thinking, access prior knowledge)	Read the Grouchy Ladybug to students. The students will keep track of the intervals of time using small plastic analog clocks. Students will then be asked probing questions (such as What are some ways that you can keep track of time? What are some things that you do that take up a great deal of time?) for a brief discussion leading into how they can solve problems based on time.			Teacher will read out The Grouchy Ladybug to students while displaying the book on the overhead projector, so all students have the opportunity to see the book.	Students are listening attentively to the story while using small handheld analog clocks (provided by the teacher) to keep track of the intervals of time (i.e. students will have their clocks display 1:00 when the book mentions the time of the day is 1:00).
Explore (Collaborative and hands-on)	Students will be given a three-part recording sheet where they will be asked to answer questions based on the scenario given such as, “What do you notice? What info do you have to solve? Explain how you would solve this using a complete sentence.” This scenario will focus on finding the end time after analyzing elapsed time.			Teacher will call on random students to answer questions on recording sheet.	Students are expected to answer questions when called on and record their ideas and answers on the given recording sheet.
Explain (student and teacher discourse, teacher modeling, vocabulary instruction, clarify misconceptions)	Afternoon scenario (as written in the explain portion below). Students need to keep track of all the intervals of time that are being explored as they work to solve the problem using the same recording sheet as used in the Explore portion. This problem will focus on students finding elapsed time given start and end time.			Teacher will call on random students to answer questions on recording sheet.	Students are expected to answer questions when called on and record their ideas and answers on the given recording sheet.
Elaborate (Extend or apply the learning to a new setting; active and collaborative)	Students will begin a we do, you do sheet which focuses on using timelines as a strategy to solve problems. This will focus on finding both elapsed time and end time while using non-benchmark units of time.			Teacher will reinforce the idea of how timelines can help students solve for both end time and elapsed time on the we do section.	Students will solve the question on the we do using timelines.
Evaluate (Students demonstrate their understanding. How will you know what they’ve learned?)	Students will complete exit ticket on you do section of paper.			Teacher will monitor students and grade the exit ticket when students are finished.	Students will work quietly and diligently on the exit ticket.
Plans for Differentiated Instruction/Accommodations
Special Education Students		Students will be instructed to use manipulatives to follow along the lesson to better visualize the concept being presented. Students will be read the story at a slower pace, so these students have the time to understand what is read.
English Language Learners		Directions will be modeled and displayed for students who cannot easily follow oral English instruction.
Gifted and Talented		Students who display advanced speed and understanding of the lesson will be given the opportunity to work with…
Other:		N/A
Potential Challenges/Plan B
Should behavior, change of schedule, shortage of supplies, or other extenuating circumstances become an issue, the lesson will be broken up into a two-day lesson in which half of the class will be following the given lesson while another will be reviewing previously taught material.
