Topic+Thirteen

= Topic Thirteen: More Addition, Subtraction, and Length = Pacing (Duration of Unit): 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 precisions. 7. Look for and make use of structure. 8. Look for and express regularity in repeated reasoning. ||

 * __**Transfer:**__
 * Standards for Mathematical Practices**
 * __**Established Goals:**__
 * 2.MD.5 ** Use addition and subtraction within 100 to solve word problems involving lengths that are given in the same units, e.g., by using drawings (such as drawings of rulers) and equations with a symbol for the unknown number to represent the problem.

__**Student I Can Statements**__
 * I can find the difference in length between two objects using standard units.
 * I can solve problems about measurement. ||
 * __**Big Ideas:**__

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

Mathematics content and practices can be applied to solve problems. || __**Essential Questions:**__
 * Practices, Processes, and Proficiencies**
 * How can you add and subtract lengths? ||
 * __**Students will know...**__
 * Measurements in the same unit can be added or subtracted in the same way as adding and subtracting whole numbers. The measurement unit needs to be written with the sum or difference.
 * Pictures and equations can be used to solve word problems involving measurements. Measurements can be added and subtracted in the same way as other whole numbers.
 * A sum can be represented as the total length of two line segments on a number line. A subtraction problem can be represented as the difference of two line segments on a number line
 * Good math thinkers know how to pick the right tools to solve math problems.
