It's always nice if you can think up a few examples to illustrate what some of these questions mean.
This is where mixed operations worksheets help; they encourage students to notice and use the correct operation.
Observation skills related to operational signs, we have found, are quite beneficial to student achievement in mathematics. Math worksheets that include mixed addition and subtraction pages with one operation per question.
Whether you are differentiating the learning in your classroom or want something for the whole group, you will probably find it here.
Math worksheets that include mixed addition, subtraction, multiplication and division pages with one operation per question. We have included a mixture of multiple operations worksheets for many different levels.
