ITL516 Math Lesson Plan Lesson Plan: Rounding Numbers and Time in 3rd Grade Standards CCSS.MATH.CONTENT.3.NBT.A.1: Use place value understanding to round whole numbers to the nearest 10 or 100. ELD.PL3.1: Exchange information and ideas with others through oral collaborative discussions on a range of social and academic topics. Objective Students will, in a classroom environment, be able to round whole numbers to the nearest ten and time to the nearest hour by using the strategy of number lines and manipulatives, with the support of visual aids and worksheets, with 80% accuracy as measured by their performance on a structured worksheet and teacher observation during group activities. Materials Interactive Whiteboard Math learning Center app Number line charts * Clock with movable hands * Worksheets for rounding numbers and time Lesson Sequence Opening (10 minutes) 1. Introduction to Rounding: * Discuss what rounding is and provide simple examples (e.., rounding 45 to 50). Explain the common misconception: Rounding always goes up (clarify this). 2. Introduction to Time Rounding: * Demonstrate how rounding works with time, using a clock. + Emphasize that rounding depends on the closeness to the hour or half-hour. Group Activities (10-15 minutes rotations) * Group 1 (Tate, Melvin, Fabiola) + Activity: Use a number line on the worksheet to round numbers to the nearest ten. Students will choose a number from the worksheet and place it on the number line to determine which two tens it falls between. They will then decide whether the number rounds up or down by seeing which ten it is closest to. * Task/Skill: Work on rounding whole numbers from the worksheets. Recognizing the tens place and how numbers relate to it and correctly identifying when to round a number up or down based on its position on the number line. * Goal: Focus on correcting misconceptions with Fabiola through peer support. Group 2 (Angel, Bianca, Natalie) Activity: Practicing rounding times by setting specific times on the clock and identifying the nearest hour. Students will take turns setting a time on the clock for example, 3:25 and ask their group to round it to the nearest hour. Students will then explain their reasoning. * Task/Skill: Set specific times on the clock and round to the nearest hour. Rounding off times to the nearest hour using a clock with movable hands * Goal: Reinforce skills with Bianca's strong comprehension and help Natalie learn by doing. * Group 3 (Jenny, Mario, Dwayne, James) * Activity: Combine both number and time rounding. \"Interactive Rounding Challenge on the Whiteboard\". Students will each present a series of numbers on the board for their group. Each student takes turns rounding the displayed number to the nearest ten or hundred by dragging it to the correct section on the interactive app. They will then discuss each answer as a group to ensure understanding * Task: Complete both rounding numbers and rounding time as a group. Combining number and tume rounding skills. * Goal: Provide guidance to students like Mario and Dwayne who need extra support. Closer (10 minutes) 1. Reflection: Discuss what students found challenging or easy 2. Review Key Concepts: Emphasize rounding methods for both numbers and time. 3. Exit Tickets: Check individual retention and understanding. 4. Homework Assignment: A worksheet reinforcing today's lesson, tailored to challenge proficient students and support those approaching proficiency. Assessment Informal observation during group activities. Completion and accuracy of rounding worksheets will show understanding. * Evaluate understanding through explanations. Check individual retention and understanding. Differentiation Provide additional visual aids or manipulatives for students needing more support. Offer challenge problems for students like Melvin who quickly grasp the concepts
