Number
and operations. The student applies mathematical process standards to develop
and use strategies for whole number addition and subtraction computations in
order to solve problems. The student is expected to:
(1) use concrete and pictorial models to determine the sum of a multiple of
10 and a one-digit number in problems up to 99;
(A) use objects and pictorial models to solve
word problems involving joining, separating, and comparing sets within 20
and unknowns as any one of the terms in the problem such as 2 + 4 = [ ]; 3 + [ ] = 7; and 5 = [ ] - 3;
(B) compose 10 with two or more addends with
and without concrete objects;
(C) apply basic fact strategies to add and subtract within 20, including making 10 and decomposing a number leading to a 10;
(D) explain strategies used to solve addition and subtraction problems
up
to 20 using spoken words, objects, pictorial models, and
number sentences; and
(E) generate and solve problem situations when given a number sentence
involving addition or subtraction of numbers within 20.
