(for more information visit www.georgiastandards.org)

M3N2 Students will further develop their skills of addition and subtraction and apply them in problem solving.
a. Use the properties of addition and subtraction to compute and verify the results of computation.
b. Use mental math and estimation strategies to add and subtract.
c. Solve problems requiring addition and subtraction.
M3P1 Students will solve problems that arise in mathematics and in other contexts.
a. Solve non-routine word problems using the strategy of logical reasoning as well as all strategies learned in previous grades.
b. Solve single and multi-step routine word problems related to all appropriate third grade math standards.
c. Determine the operation(s) needed to solve a problem.
d. Determine the most efficient way to solve a problem (mentally, paper/pencil, or calculator).
M3P2 Students will investigate, develop, and evaluate mathematical arguments.
M3P3 Students will use the language of mathematics to express ideas precisely.
M3P4 Students will understand how mathematical ideas interconnect and build on one another and will apply mathematics in other content areas.
M3P5 Students will create and use pictures, manipulatives, models, and symbols to organize, record, and communicate mathematical ideas.
