Checks for Understanding (Formative/Summative Assessment)


Time - Reads and write time to the nearest minute. ( 3.MD.1 )


Money - Compare and order decimal amounts in the context of money. ( 4.MD.2 )


Coins - Count the value of combinations of coins and bills up to five dollars. ( 2.MD.8 )


Relevant Information - Analyze problems by identifying relationships, distinguishing relevant from irrelevant information, and observing patterns.


Break Problems - Determine when and how to break a problem into simpler parts.


Estimation - Use estimation to check answers for reasonableness, and calculators to check for accuracy.


Conjectures - Make and investigate mathematical conjectures


Properties - Explain and justify answers on the basis of mathematical properties, structures, and relationships. ( 3.OA.5 )


Commutative Property - Use manipulatives to demonstrate that the commutative property holds for addition but not for subtraction. (3.OA.5 )


Oral Math Language - Use correct, clearly written and oral mathematical language to pose questions and communicate ideas.


Strategies for Solving Problems - Develop strategies for solving problems involving addition and subtraction of measurements. (3.MD.1 )


Mathematical Thinking - Analyze and evaluate the mathematical thinking and strategies of others.


Use Representations - Create and use representations to organize, record, and communicate mathematical ideas.


Convey Ideas of Mathematics - Use age-appropriate books, stories, and videos to convey ideas of mathematics.
