Practice solving 1- and 2-step word problems by adding and subtracting 2-digit numbers with this set of 16 task cards. Solve Addition & Subtraction Word Problems In this math activity, your students will continue building the relationship between addition and subtraction while honing the skills fo...
According to the National Council of Teachers of Mathematics (1980), the focus of school mathematics in the 1980s must be on problem solving. Furthermore, computation is to be a tool for problem solving. The importance of problem solving as a goal in mathematics education cannot be disputed;...
Significant effects were also evident for grade and operation (addition, subtraction, multiplication, and division). The findings highlight the need for math instruction to move from a focus on computation to problem-solving activities, including word problems of varying structures. Further, test ...
