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;

- (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);
