Bring this easy shortcut to your first grade addition lesson!  By adding doubles (6+6, for example), and then adding or subtracting 1, kids learn how to solve simple addition problems with ease. This trick is especially helpful for...

Graph A goes with equation C, but table B. The short assessment task requires class members to match graphs with their corresponding tables, equations, and verbalized rules. Pupils then provide explanations on the process they used to...

Don't forget the tables! The previous lessons in this five-part series examined the linear equation and graph relationship. The current lesson adds tables to the mix. At completion, individuals should be able to create a table of values,...

Looking for a real-world situation to practice converting units? In this problem, learners must change miles per gallon to liters per km (or vice versa) to determine which car gets better gas miileage. It is a relatively short problem,...

An exercise in finding the area of polygons by decomposing into triangles and composing into rectangles is the focus of this resource. Make several copies of the worksheet for each participant. Ask learners to use colored pencils to...

A resource that makes for excellent group work as students explore the area and perimeter of different complex designs made up of squares and circles. The commentary gives a clear definition of perimeter, but suggests that group members...

Scholars construct three-dimensional figures to study dimension and side views. Learners build models using linking cubes to match views of different sides. After practicing with models, they attempt to match three-dimensional drawings...

In this multiplication facts activity, 4th graders solve multiplication problems, find the missing numbers, and solve a word problem. In this problem solving activity, students find seventeen products. Examples of drawing pictures and...

In this order of operations (i.e., addition, subtraction, multiplication, division) worksheet, students solve 3 word problems demonstrating their understanding of the concept.

In this addition and subtraction worksheet, students use their problem solving skills to solve 41 problems as they fill in the missing numbers in each of the problems.

In this counting back one, two and three worksheet, students, with a partner, problem solve and answer six word problems and equations.

Lengthen learners' long division skills with this single-page handout. They must use problem solving skills to find the quotient when a four-digit number is divided by one digit. This is a nice assignment for early in the process of...

In this math puzzle worksheet, students use their subtraction skills to solve a math puzzle and write an explanation of their problem solving strategy.

In this trigonometry instructional activity, students play a skill review game that involves the problem solving strategy of working backward.  The game is similar to tic-tac-toe using the trigonometric ratios.  The one page...

Thirty at the party won't cost any more than twenty-five. The assessment task provides a scenario for the cost of a party where the initial fee covers a given number of guests. The class determines the cost for specific numbers of guests...

Just how big would it really be? Young mathematicians determine if different toys are proportional and if their scale is accurate. They solve problems relating scale along with volume and surface area using manipulatives. The...

Weighted averages can be tricky to explain! However, this study guide makes it easy for teachers by including definitions, explanations, and breaking down problems into three steps. Includes mixture problems and uniform motion problems.

Population density, it is not all that it is plotted to be. Pupils analyze a scatter plot of population versus area for some of the states in the US. The class members respond to eight questions about the graph, specific points and...

This activity gets at the heart of algebraic reasoning and setting up equations with one variable to solve real-world problems. The worksheet has only one problem, but it requires that learners first use their own reasoning...

Pupils design a fence for a backyard pool. Scholars develop a fence design based on given constraints, determine the amount of material they need, and calculate the cost of the project. 

When is the last time you assigned your students only one problem? This seemly simple problem requires learners think like a mathematician and reason about how to solve this compound inequality in one variable. More than just using...

In this writing equations worksheet, 9th graders solve and complete 20 different problems that include writing an equation and finding a solution for each problem. First, they read the problem through and write an equation that best...

Finding common denominators is an important strategy when adding fractions with unlike denominators. In the first two questions in this three-question task, fifth graders are asked to combine fractions and draw a picture to show their...

Explore the measures of central tendency through a challenging task. Given values for the mean, median, mode, and range, collaborative groups create a set of data that would produce those values. They then critique other answers and...
