Number and operations. The student applies
mathematical process standards to develop and use strategies and methods for
whole number computations in order to solve addition and subtraction problems
with efficiency and accuracy. The student is expected to:
(1) recall basic facts to add and subtract within 20 with automaticity;
(A) add up to
four two-digit numbers and subtract two-digit numbers using mental strategies
and algorithms based on knowledge of place value and properties of operations;
(B) solve one-step
and multi-step
word problems involving addition
and subtraction within 1,000 using a variety of strategies
based on place value, including algorithms; and
(C) generate and solve problem situations for a given mathematical
number sentence involving addition and subtraction of whole numbers within 1,000.
