Transfer: Standards for Mathematical Practices 1. Make sense of problems and persevere in solving them. 2. Reason abstractly and quantitatively.
3. Construct viable arguments and critique the reasoning of others.
4. Model with mathematics. 5. Use appropriate tools strategically. 6. Attend to precision.
7. Look for and make use of structure. 8. Look for and express regularity in repeated reasoning.

Established Goals:

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.

Prerequisite Standards: 2.MD.7 Tell and write time from analog and digital clocks to the nearest five minutes, using a.m. and p.m.

Big Ideas:

Measurement
Some attributes of objects are measurable and can be quantified using unit amounts.

Practices, Processes, and Proficiencies
Mathematics content and practices can be applied to solve problems.

Essential Questions:

How can lengths of time be measured and found?

Students will know...
Time can be expressed using different units that are related to each other.
The minute hand takes 5 minutes to move from one number to the next on a typical clock face. The minute hand takes 1 minute to move from one mark to the next on a typical clock face.
There are different units for measuring time. Many clock times can be expressed in more than one way.
The duration of an event can be measured if one knows the start and end times for the event.
Some problems with the initial data point unknown can be solved by starting with the end result, reversing the steps and processes, and working backward to the initial data point.

12-1 Time can be expressed using different units that are related to each other.

12-2 The minute hand takes 5 minutes to move from one number to the next on a typical clock face. The minute hand takes 1 minute to move from one mark to the next on a typical clock face.

12-3 There are different units for measuring time. Many clock times can be expressed in more than one way.

12-4 The duration of an event can be measured if one knows the start and end times for the event.

12-5 Some problems with the initial data point unknown can be solved by starting with the end result, reversing the steps and processes, and working backward to the initial data point.
