Unit Title: Understanding Addition & Subtraction
Unit Assessment Date: August 22, 2014
Length of Unit: 10 days
August 11th-22nd, 2014
Unit Standards: What standards will I explicitly teach and intentionally
assess?
2.OA.1 Use addition & subtraction within 100 to solve one and two step word problems
involving situations of adding two, taking from, putting together, taking apart, and
comparing with unknown and all positions, e.g., by using drawings and equations with
a symbol for the unknown number to solve the problem.
2.NBT.5 Fluently add and subtract within 100 using strategies based on place value,
properties of operation and/or the relationship between addition and subtraction.
21st Century Skills/ Mathematical Practices —How can I provide opportunities
for my students to collaborate, communicate, think critically, and be creative?
1. Make sense of problems and persevere in solving them.
2. Reason abstractly and quantitatively.
3. Construct viable arguments.
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
Grade/Teacher: 2nd-Carter
Materials and Resources Needed:—Other than Envisions, what other
materials and resources will be utilized during unit instruction? (Be sure to
incorporate mathematical vocabulary during instruction.)


Reteaching, enrichment and practice pages based on students’ needs (should
be used in conjunction with manipulatives)
