Description: Having a classroom campout this year? Here's a fun way for your first graders to practice addition and subtraction within 18. Just choose the answer to the equation and click it. There are 4 sets of 10 cards which can be practiced independently by clicking on an icon. Set 1: Addition within 10 Set 2: Addition within 18 Set 3: Subtraction within 10 Set 4: Subtraction within 18 TEKS 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: 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; Common Core Use addition and subtraction within 20 to solve word problems involving situations of adding to, taking from, putting together, taking apart, and comparing, with unknowns in all positions, e.g., by using objects, drawings, and equations with a symbol for the unknown number to represent the problem.
