After solving each multiplication sentence square, pupils color the numbers according to the key. What does the mystery picture make? Class members take a swing at problem solving to find out.

Given a certain amount of points, how many line segments can you connect between them? How many close geometric figures can you create? These are the types of questions learners are asked to solve in a assessment-based worksheet.

How long do we have to wait? Given several days of times between eruptions of Old Faithful, learners create a graphical representation for two days. Groups combine their data to determine an appropriate wait time between eruptions.

Learn to visualize mathematical patterns as a folded pattern. Beginning with a visual display, the task encourages pupils to view sequences as a folded table. The pattern of the table then becomes a formula in a spreadsheet that...

Study the difference between mass and weight. Your math group will compare the weight of an item to the amount of space that it uses. They'll then use conversion factors to find the difference between kilograms and pounds. Essential...

Context makes everything better! Groups use real data to create models and make predictions. Classmates compare an exponential model to a linear model, then consider the real-life implications. 

Assign an interactive poster activity to assess your class's knowledge and skill concerning data analysis. The teacher reference provides solid questions to ask individuals or groups as they complete their posters.

Class members investigate how positive and negative numbers are useful in the real world. Individuals first read a short passage and identify terms indicating positive and negative numbers. They consider situations involving positive...

Math class is full of drama—there are so many problems to work out! Pupils work out factoring problems. They use quadratic methods of factoring higher degree polynomials, in addition to factoring the sum and difference of two...

How do you create a residual plot? Work as a class and in small groups through the activity in order to learn how to build a residual plot. The activity builds upon previous learning on calculating residuals and serves as a...

What properties does area possess? Solidify the area properties that pupils learned in previous years. Groups investigate the five properties using four problems, which then provide the basis for a class discussion.

As they investigate scaling figures and calculate the resulting areas, groups determine the area of similar figures. They continue to investigate the results when the vertical and horizontal scales are not equal. 

Are pyramids and cones similar in definition to prisms and cylinders? By examining the definitions, pupils determine that pyramids and cones are subsets of general cones. Working in groups, they continue to investigate the relationships...

What function will describe the insect population growth? Pairs or small groups work together to determine which type of function and specific function will model given scenarios. The scenarios differentiate between linear,...

Pupils analyze group data to identify significant differences. They use simulation to create their own random assignment data for comparison. 

Show your class members that if they can graph a linear function, they can graph an absolute value function. Groups create an absolute value graph using a table, then entertain the idea of an absolute value function defined as two...

What happens to a function whose graph is translated horizontally? Groups find out as they investigate the effects of addition and subtraction within a function. This nineteenth lesson in a 26-part series focuses on horizontal...

Groups sort through NASA data provided in a graphic to create a graph using uniform units and intervals. Individuals then make connections to the increasing, decreasing, and constant intervals of the graph and relate these...

Does complex number multiplication have the class spinning? Here's a resource that helps pupils explore and discover the geometric effect of multiplying complex numbers. In the 14th installment in the 32-part unit groups look at the unit...

Class members use the powers of multiplication in the 19th installment of the 32-part unit has individuals to utilize what they know about the multiplication of complex numbers to calculate the integral powers of a complex...

Third graders use strips of paper to find equivalent fractions. They will fold paper into thirds and shade 2/3 of the paper. Then fold the same paper in six parts and predict how many parts will be shaded. They will repeat again folding...

Here is a fabulous lesson on problem solving in the mathematical world. In it, third and fourth graders get lots of great coaching on how to approach word problems, and how to best find a solution. They watch an episode of Reading...

Everyone loves pizza! Learners define fractions and use manipulatives to calculate fractions. Kids cut circles to represent various fractional parts of a pizza. Some accommodations are included. 

Have you ever tried to light ice on fire? With methane hydrate, you can do exactly that. The ice forms with methane inside so it looks like ice, but is able to burn. The instructional activity uses group research and a hands-on activity...
