M2N2
Students will build fluency with multi-digit addition and subtraction.
a.
Correctly add and subtract two whole numbers up to three digits each
with regrouping.
b. Understand and use the inverse relation between addition and
subtraction to solve problems and check solutions.
c. Use mental math strategies such as benchmark numbers to solve
problems.
d. Use basic properties of addition (commutative, associative, and
identity) to simplify problems (e.g., 98 + 17 by taking two from 17 and
adding it to the 98 to make 100 and replacing the original problem by
the sum 100 + 15).
e. Estimate to determine if solutions are reasonable for addition and
subtraction.
M2P1
Students will solve problems that arise in mathematics and in other
contexts.
a.
Solve non-routine word problems using the strategies of use or look for
a pattern or guess and check as well as all strategies learned in
previous grades.
b. Solve single step routine word problems related to all appropriate
second 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).
