Math 1.5
Algebraic reasoning. The student applies mathematical process standards to identify and apply number patterns within properties of numbers and operations in order to describe relationships. The student is expected to:
- (1) recite numbers forward and backward from
any given number between 1 and 120;
- (A) skip count by twos, fives, and tens to determine the total number of objects up to 120 in a set;
- (B) use relationships to determine the number that is 10 more and 10 less than a given number up to 120;
- (C) represent word problems involving addition and subtraction of whole numbers up to 20 using concrete and pictorial models and number sentences;
- (D) understand that the equal sign represents a relationship where expressions on each side of the equal sign represent the same value(s);
- (E) determine the unknown whole number in an addition or subtraction equation when the unknown may be any one of the three or four terms in the equation; and
- (F) apply properties of operations to add and subtract two or three numbers.
