**Name/Title of the resource:**"Elapsed Time: Using a Timeline to Determine Elapsed Time" from Illuminations

**URL:**https://illuminations.nctm.org/Lesson.aspx?id=3966

**How you found it:**I have used the illuminations website before and found good resources so I tried it again. I searched time and 3rd grade. I found this lesson that covers the same standard as my lesson.

**How you might use it in your final project:**I could use this timeline as a resource for my students, and I could use these activities for students who need extra practice with calculating time.

**What standards does the resource address:**

NCTM Standards and ExpectationsDevelop fluency in adding, subtracting, multiplying, and dividing whole numbers.

Develop and use strategies to estimate the results of whole-number computations and to judge the reasonableness of such results.

Select and apply techniques and tools to accurately find length, area, volume, and angle measures to appropriate levels of precision.

Common Core State Standards – MathematicsGrade 3, Measurement & Data

CCSS.Math.Content.3.MD.A.1

Tell and write time to the nearest minute and measure time intervals in minutes. Solve word problems involving addition and subtraction of time intervals in minutes, e.g., by representing the problem on a number line diagram.

Grade 4, Measurement & Data

CCSS.Math.Content.4.MD.A.2

Use the four operations to solve word problems involving distances, intervals of time, liquid volumes, masses of objects, and money, including problems involving simple fractions or decimals, and problems that require expressing measurements given in a larger unit in terms of a smaller unit. Represent measurement quantities using diagrams such as number line diagrams that feature a measurement scale.

**Name/Title of the resource:**The One-Handed Clock in a Digital Era

**How you found it:**@gfletchy tweeted about this post from his blog. I follow him on twitter, because his twitter is part of my PLN!

**How you might use it in your final project:**Although my lesson is about calculating time to the exact minute, this article gives ideas on how to teach students to estimate time using an analog clock. This would be something that I think could be possible to teach prior to my lesson.

**What standards does the resource address:**

**MCC2.MD.7**– Tell and write time from analog and digital clocks to the nearest five minutes, using a.m. and p.m.

**Name/Title of the resource:**Teaching Elapsed Time: Strategies That Work

**URL:**http://www.scholastic.com/teachers/top-teaching/2013/01/teaching-elapsed-time-strategies-work

**How you found it:**I google searched "teaching calculating elapsed time" and many results popped up. I saw this one by Scholastic, which is a website I trust and have used before.

**How you might use it in your final project:**This website has a some really good strategies for teaching about time. I could use a few of these strategies if I notice my students need practice in a particular area. Like perhaps timing them during different activities in the day, or talking about the students schedules during the day and how time elapses.

**What standards does the resource address:**This website doesn't list any specific standards, but I would argue that it addresses the following:

**MCC2.MD.7**– Tell and write time from analog and digital clocks to the nearest five minutes, using a.m. and p.m.

**CCSS.Math.Content.3.MD.A.1**

Tell and write time to the nearest minute and measure time intervals in minutes. Solve word problems involving addition and subtraction of time intervals in minutes, e.g., by representing the problem on a number line diagram.
