3.3.3A Time
Overview
Standard 3.3.3 Essential Understandings
Third graders tell time to the nearest minute (includes five minute intervals) on analog and digital clocks. In addition, they determine elapsed time to the nearest minute within a two hour interval. They know and understand the relationship between seconds, minutes, hours, days, weeks, months and years.
Third graders make change up to one dollar in several different ways. They are able to make change with as few coins as possible.
Third graders use analog thermometers to determine temperatures to the nearest degree in both Fahrenheit and Celsius.
Benchmark Group A
3.3.3.1 Tell time to the minute using digital and analog clocks. Determine elapsed time to the minute.
3.3.3.2 Know relationships among units of time.
What students should know and be able to do [at a mastery level] related to these benchmarks:
 tell time to the nearest five minutes
 tell time to the nearest minute
 determine elapsed time to the nearest minute within a two hour span
 solve problems involving elapsed time
 find start time given end time and elapsed time
 find end time given start time and elapsed time
 make the following conversions
 minutes to hours
 hours to minutes
 hours to days
 days to hours
 days to weeks
 weeks to days
 months to years
 years to months
 make conversions involving mixed units.
 For example, 12 days = 1 week and 5 days.
Work from previous grades that supports this new learning includes:
 Tell time to the hour, half hour and quarter hour
 Distinguish between a.m. and p.m.
 Use the language "quarter to," "quarter after'" "fifteen minutes after" and "fifteen minutes before."
NCTM Standards
Common Core State Standards
Solve problems involving measurement and estimation of intervals of time, liquid volumes, and masses of objects.
3.MD.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.
3.MD.2. Measure and estimate liquid volumes and masses of objects using standard units of grams (g), kilograms (kg), and liters (l).1 Add, subtract, multiply, or divide to solve onestep word problems involving masses or volumes that are given in the same units, e.g., by using drawings (such as a beaker with a measurement scale) to represent the problem.
Misconceptions
Students may think ....
 the hour and minute hand on analog clocks are interchangeable.
 the hour numeral is also the minute numeral
 there is no difference between minutes to the hour, minutes after the hour and minutes past the hour and they can use the words interchangeably.
 a.m. and p.m. are one and the same.
Resources
Teacher Notes
 Students may need support in further development of previously studied concepts and skills.
 The following conversions are part of understanding time at the third grade level:
 minutes to hours
 hours to minutes
 hours to days
 days to hours
 days to weeks
 weeks to days
 months to years
 years to months
 Third graders need to find a conversion involving mixed units.For example, 12 days = 1 week and 5 days
 Elapsed time must be within a two hour span.
 Using an empty time line can aid students in finding elapsed time.
For example,
 Good questions, and good listening, will help children make sense of the mathematics, build selfconfidence and encourage mathematical thinking and communication. A good question opens up a problem and supports different ways of thinking about it. The best questions are those that cannot be answered with a "yes" or a "no."

New Vocabulary
"Vocabulary literally is the key tool for thinking."
Ruby Payne

p.m.  after noon
unit  standardized quantity of measurement
Mathematics vocabulary words describe mathematical relationships and concepts and cannot be understood by simply practicing definitions. Students need to have experiences communicating ideas using these words to explain, support, and justify their thinking.
Learning vocabulary in the mathematics classroom is contingent upon the following:
Integration: Connecting new vocabulary to prior knowledge and previously learned vocabulary. The brain seeks connections and ways to make meaning which occurs when accessing prior knowledge.
Repetition: Using the word or concept many times during the learning process and connecting the word or concept with its meaning. The role of the teacher is to provide experiences that will guarantee connections are made between mathematical concepts, relationships, and corresponding vocabulary words.
Meaningful Multiple and varied opportunities to use the words in context. These
Use: opportunities occur when students explain their thinking, ask clarifying questions, write about mathematics, and think aloud when solving problems. Teachers should be constantly probing student thinking in order to determine if students are connecting mathematics concepts and relationships with appropriate mathematics vocabulary.
Strategies for vocabulary development
Students do not learn vocabulary words by memorizing and practicing definitions. The following strategies keep vocabulary visible and accessible during instruction.
Mathematics Word Bank: Each unit of study should have word banks visible during instruction. Words and corresponding definitions are added to the word bank as the need arises. Students refer to word banks when communicating mathematical ideas which leads to greater understanding and application of words in context.
Labeled pictures and charts: Diagrams that are labeled provide opportunities for students to anchor their thinking as they develop conceptual understanding and increase opportunities for student learning.
Frayer Model: The Frayer Model connects words, definitions, examples and nonexamples.
Example/Nonexample Charts: This graphic organizer allows students to reason about mathematical relationships as they develop conceptual understanding of mathematics vocabulary words. Teachers should use these during the instructional process to engage student in thinking about the meaning of words.
Vocabulary Strips: Vocabulary strips give students a way to organize critical information about mathematics vocabulary words.
word  definition  illustration 
Encouraging students to verbalize thinking by drawing, talking, and writing increases opportunities to use the mathematics vocabulary words in context.

Struggling Learners
Using an empty time line can aid students in finding elapsed time.
For example,
Concrete  Representational  Abstract Instructional Approach
(Adapted from The Access Center: Improving Access for All K8 Students)
The ConcreteRepresentationalAbstract Instructional Approach (CRA) is a researchbased instructional strategy that has proven effective in enhancing the mathematics performance of students who struggle with mathematics.
The CRA approach is based on three stages during the learning process:
Concrete  Representational  Abstract
The Concrete Stage is the doing stage. The concrete stage is the most critical in terms of developing conceptual understanding of mathematical skills and concepts. At this stage, teachers use manipulatives to model mathematical concepts. The physical act of touching and moving manipulatives enables students to experience the mathematical concept at a concrete level. Research shows that students who use concrete materials develop more precise and comprehensive mental representations, understand and apply mathematical concepts, and are more motivated and ontask. Manipulatives must be selected based upon connections to the mathematical concept and the students' developmental level.
The Representational Stage is the drawing stage. Mathematical concepts are represented using pictures or drawings of the manipulatives previously used at the Concrete Stage. Students move to this level after they have successfully used concrete materials to demonstrate conceptual understanding and solve problems. They are moving from a concrete level of understanding toward an abstract level of understanding when drawing or using pictures to represent their thinking. Students continue exploring the mathematical concept at this level while teachers are asking questions to elicit student thinking and understanding.
The Abstract Stage is the symbolic stage. Teachers model mathematical concepts using numbers and mathematical symbols. Operation symbols are used to represent addition, subtraction, multiplication and division. Some students may not make a clean transfer to this level. They will work with some symbols and some pictures as they build abstract understanding. Moving to the abstract level too quickly causes many student errors. Practice at the abstract level will not lead to increased understanding unless students have a foundation based upon concrete and pictorial representations.

 Using an empty time line can aid students in finding elapsed time.
For example,
 Word banks need to be part of the student learning environment in every mathematics unit of study. Refer to these throughout instruction.
 Word Use vocabulary graphic organizers such as the Frayer model (see below) to emphasize vocabulary words count, first, second, third, etc.
 Sentence Frames
Math sentence frames provide support that English Language Learners need in order to fully participate in math discussions. Sentence frames provide appropriate sentence structure models, increase the likelihood of responses using content vocabulary, help students to conceptualize words and build confidence in English Language Learners.
Sample sentence frames related to these benchmarks:
Elapsed time means ________________________________________. 
 When assessing the math skills of an ELL student it is important to determine if the student has difficulty with the math concept or with the language used to describe the concept and conceptual understanding.
