The purpose of this task is to present students with a context that can naturally be represented with an inequality and to explore the relationship between the context and the mathematical representation of that context; thus, this is an intended as an instructional task.

Download these free worksheets to sharpen your math skills. These St. Patrick's Day math worksheets focus on topics such as patterning, comparing numbers, counting, word problems, addition, multiplication, and mixed operations.

This task uses language, "half of the stamps," that students in Grade 5 will come to associate with multiplication by the fraction 12. In Grade 3, many students will understand half of 120 to mean the number obtained by dividing 120 by 2. For students who are unfamiliar with this language the task provides a preparation for the later understanding that a fraction of a quantity is that fraction times the quantity.

This problem can be solved in more than one way. The choice in solution method may reflect the comfort and mathematical sophistication of the student.

This is a multi-step problem since it requires more than two steps no matter how it is solved. The problem is not scaffolded for the student, but each step is straightforward and should follow from the previous with a careful reading of the problem.

You will learn how to solve multi-step linear inequalities in this lesson. Besides typical math questions, you are going to see word problems related to multi-step linear inequalities and money. [8:15]

This is a video and interactive assessment activity designed to help first graders learn about subtraction word problems up to twenty.

This course features a video review and an assessment practice of subtracting by crossing out with pictures for word problems. It is aimed at first grade math students.

The purpose of this task is to address the concept of opportunity cost through a real world context involving money.

This real world word problem about calculating a tip in a restaurant requires multiple steps.

This series of word problems requires students to determine which problems can be solved by multiplying 1/8_2/5.

Have you ever seen an item that you wanted on sale for 15% of its original price? Have you tried to figure out what the sale price would be? Using this interactive lesson from T.V. 411, you can learn to calculate discounts with percentages.

Find a quick, concise explanation of how to take the words from problems and substitute variables, operations and numbers to create an equivalent expression. Examples are given and clearly explained.

This problem is the fifth in a series of seven about ratios. In the first problem students define the simple ratios that exist among the three candidates. It opens an opportunity to introduce unit rates. The subsequent problems are more complex. In the second problem, students apply their understanding of ratios to combine two pools of voters to determine a new ratio. In the third problem, students apply a known ratio to a new, larger pool of voters to determine the number of votes that would be garnered.

This is the sixth problem in a series of seven that use the context of a classroom election. While it still deals with simple ratios and easily managed numbers, the mathematics surrounding the ratios are increasingly complex.

This is the last problem of seven in a series about ratios set in the context of a classroom election. Since the number of voters is not known, the problem is quite abstract and requires a deep understanding of ratios and their relationship to fractions.
