This resource contains a lesson on the slope and y-intercept of a line and how to interpret them in word problems.

Contains plans for two lessons that explain how to use the question-answer relationship (QAR) strategy to make word problems easier to understand. In addition to objectives and standards, these instructional plans contain links to sites used in the lessons as well as assessment and reflection activities.

This tasks gives a verbal description for computing the perimeter of a rectangle and asks the students to find an expression for this perimeter. Students then have to use the expression to evaluate the perimeter for specific values of the two variables.

This task is a natural follow up for task Rectangle Perimeter 1. After thinking about and using one specific expression for the perimeter of a rectangle, students now extend their thinking to equivalent expressions for the same quantity.

The purpose of this task is to ask students to write expressions and to consider what it means for two expressions to be equivalent.

This task is written so that students have opportunities to use different strategies to determine whether a set has an even or odd number of objects.

Solve word problems by modeling real-world (and not-so-real) situations as right triangles and using trigonometry.

The purpose of this task is for students to compare two fractions that arise in a context. Because the fractions are equal, students need to be able to explain how they know that.

A set of examples and exercises that cover how to solve population problems by using exponents and logarithms.

This word problem may be used for instructional or assessment purposes, depending on where students are in their understanding of addition and how the teacher supports them.

There are a couple of ways to solve this real world word problem.

Students gain experience and practice with three types of word problems using the "Take From" context: result unknown, change unknown, and start unknown.

This word problem is based estimating the height of a person over time. Note that there is a significant amount of rounding in the final answer. This is because people almost never report their heights more precisely than the closest half-inch. If we assume that the heights reported in the task stem are rounded to the nearest half-inch, then we should report the heights given in the solution at the same level of precision.

Take a quiz that focuses on fractions in word problems. Summary of the score is shown at the end of the quiz, and students may review missed questions.
