Collaborative groups work with geometry manipulatives to investigate conjectures about angles. They create a graphic organizer to use in summarizing relationships among angles in intersecting, perpendicular and parallel lines cut by a...

Students make constructions and conjectures. In this geometry lesson, students construct right, acute and obtuse angles using a straight edge and a protractor. They investigate parallel lines and the angles formed by the angles.

Mo' money, mo' problems! But don't worry, here is an assessment that proves to young mathematicians that they can solve actual money problems. The resource includes 11 money problems involving addition, subtraction, multiplication,...

Are congruent shapes compatible? Congruent shapes are identical to one another, and throughout the assessment, young mathematicians identify given shapes as congruent.

Frequency polygons are a different way to represent frequencies over intervals. Pupils take frequencies for intervals of data from a frequency table and plot them as a frequency polygon. Budding mathematicians find information about the...

Square root and exponential powers are the focus of the assessment worksheets included in a math resource. Young mathematicians answer 10 questions, each with subset questions, involving solving a variety of exponential equations...

Multiplication and division of decimals by whole numbers is the focus of these assessment worksheets. Learners solve equations by showing their work in order to arrive at the correct answer.

Class members investigate the effect of a negative scale factor dilation on coordinate shapes as they watch a short video that shows an example of a geometric figure undergoing a dilation with a negative scale factor. Learners then try a...

Practice expanding and factoring quadratic expressions. Learners watch a video to refresh their knowledge of expanding and factoring quadratics. After they are reacquainted with the material, they attempt a worksheet of review problems.

After viewing a video on fractional amounts, young mathematicians put their new knowledge to the test. Throughout the assessment, class members find the fractional amount for prices, times, and populations. There are a few percent and...

Learners read a variety of word problems and find the mode, median, range, and mode from a given set of data. If calculators are not desirable, provide the class with notebook paper to work out the equations. 

Reinforce the concept of factors, multiples, and prime numbers with a 16-problem practice worksheet. Eight pages offer a variety of problem solving opportunities with clear objectives and tips for successful completion. 

Don't go around and around, help your class determine amounts around and in a circle with a video that connects circumference to the perimeter or the distance around an object. The resource includes 14 questions dealing with circles and...

Middle schoolers review what they comprehend about angles. They name the differnt types of angles and define them. Students use their protractors to answer questions, the teacher walks around to look at the positioning of the...

Learners demonstrate and understanding of the three types of angles using triangles and quadrilaterals. In this angles lesson plan, students learn about acute, obtuse and right angles. They use cut-outs to find the areas of triangles and...

Students operate a GPS unit to investigate the direction of glacier movement. They describe the motion of glacier movement by interpreting a graph. Students explain how scientists use glacier striations to determine glacier movement.

In this geometric calculations of solar storms activity, students use a diagram indicating the location of 2 STEREO satellites, the earth and the sun to calculate the distance between a Coronal Mass Ejection and the Earth. They use...

In this Pan's highway instructional activity, students read about the Cassini spacecraft that discovered how Pan clears out the ring debris in the outer A-ring system of Saturn. Students use an image taken by the satellite to find the...

Learners view a PowerPoint for a warm-up lesson. They practice measuring around the classroom, measuring such things as the length and width of a desk, pencil, door, and book. Students use a website to practice measuring angles.

In this solar storms worksheet, learners use a diagram given the location of two STEREO spacecraft satellites, a coronal mass ejection, the sun and the Earth to solve 2 problems about the coronal mass ejection. Students use segments,...

Students use geometry or trigonometry to measure the distance of a far off point. They verify their measurements using a tape measure to check their work.

Students explore the concept of triangle inequalities.  In this triangle inequality activity, students cut spaghetti noodles into given lengths.  Students use the noodles to complete a worksheet about triangle...

Students watch a segment of the PBS video which show the lemurs' ability to jump. In pairs, students collect measurement data involving each other's length of a standard step, a standing broad jump, and a long jump. They record their...

Students examine their shadows and why they are different in the summer and winter.  In this seasons instructional activity students complete an activity to see how the earth's tilt on its axis changes the length of shadows.
