I am so excited for this Math lesson! After reading Chicka Chicka 1-2-3 by Bill Martin Jr., Michael Sampson, and Lois Ehlert, we are going to be doing a fun math worksheet. The worksheet focuses on using addition and subtraction within 20 to solve word problems where objects and equations are used for the unknown number. It also includes problems to encourage an understanding in the meaning of the equal sign in determining whether an equation is true or false and determining the unknown whole number in an addition or subtraction equation.
First Grade Utah Core Math Standard: Represent and solve problems involving addition and subtraction. Objective 1: Use addition and subtraction within 20 to solve word problems involving situations of adding to, taking from, putting together, taking apart, and comparing, with unkowns in all positions. Objective 2: Solve word problems that call for addition of three whole numbers whose sum is less than or equal to 20, e.g., by using objects, drawings, and equations with a symbol for the unkown number to represent the problem.
Ed Tech Standard 8: Use technology resources (e.g., calculators, data collection probes, videos, educational software) for problem-solving, self-directed learning, and extended activities.
