MAT-03.NBT.02

 MAT-03 Targeted Standards(NBT) Domain: Number and Operations in Base TenCluster: Use place value understanding and properties of operations to perform multi­digit arithmetic. MAT-03.NBT.02 Fluently add and subtract within 1000 using strategies and algorithms based on place value, properties of operations, and/or the relationship between addition and subtraction. Fluently adding and subtracting means students are able to work accurately, efficiently, and flexibly with numbers.  The word algorithm refers to a procedure or series of steps.  This standard also requires that students have experiences that enable them to explore place value strategies and the relationships among numbers to solve problems.

Student Learning Targets:

Reasoning Targets

• I can decide what makes a strategy efficient based on the numbers in a problem.
• I understand and recognize when I need might need to regroup/trade ones, tens, hundreds in my strategy.

Skills (Performance) Targets

• I can add and subtract numbers up to 1000 to solve problems.
• I can explain the strategy I used to solve a problem.
• I can decompose numbers into place value parts to solve problems.
• I can use a strategy that ha a reasonable amount of steps to solve a problem.
