﻿Creating Time Word Problems

**Objective: Students will begin to create stories that involve elapsed time equations **

==**NYS Standards: ** ==

2.PS.4 Formulate problems and solutions from everyday situations 2.PS.8 Use manipulatives to model the action in problems2.PS.10 Explain to others how a problem was solved giving strategy and justification 2.CN.7 Recognize the presence of mathematics in their daily lives 2.CN.9 Recognize and apply mathematics to objects, pictures, and symbols 2.CM.6 Use appropriate mathematical terms, vocabulary, and language

**Key concepts:**
 * 1) **Calculate the time that has passed from the start of an activity to its end**
 * 2) **Differentiate between whole hours and partial hour (minutes) when calculating elapsed time**
 * 3) **One whole hour equals 60 minutes**



**Measure of Success: Students will be able to formulate basic elapsed time questions and identify a strategy for solving it**

 Lesson: Teacher will begin by modeling a basic morning routine where time has elapsed. "This morning, I got into the shower at 6:00 a.m. When I got out from the shower, the clock read 6:15. How long was I in the shower?" Teacher will model with the Judy clock: Start with the hour hand pointing to the six and the minute hand pointing to 12. Ask students to confirm start time. Slowly move the minute hand while students skip count by 5 for each digit on the clock face that is passed. Stop at the "3" as students say 15. Pose the question again? How many minutes have passed while I was in the shower? Have students turn and talk about a morning routine that requires time. Provide clock manipulatives for all students. Allow for a pair-shares to reinforce skill/ strategies. Follow up with students writing independent number stories about elapsed time.

Differentiated Options: //__ Audio Learners/ English Language learners __// : Students can use "Talking Tom" so that they can playback their stories or hear others as "Tom" mimics them. Students may also use interactive clock on whiteboard so that they can hear the audio as it counts the minutes going by. __// Tactile Learners/ Visual Learners //__ : Provide "Judy Clocks" for individual students. Allow students to use interactive clock on whiteboard. =**Technology: Interactive differentiation links ** = Elapsed Time Interactive game
