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...

Young scholars investigate how friction affects the movement of a block across surface areas. They test five different kinds of surfaces—smooth surface, wax paper, a paper towel, course, and fine sandpaper. They predict and record the...

Ninth graders develop operational definition of density, do computations using density equation, categorize pieces of matter as being able to float on water or not, based on density, explain why some objects sink or float based on...

Watch the damage from a forest fire in this interactive simulation activity that challenges learners to estimate the burn area using different approaches. Learners are given a worksheet to track the different burn patterns and practice...

Challenge the class with inscribed circles in triangles. The assessment task requests class members use their knowledge of circles and right triangles to prove two triangles are congruent. They go on to utilize their knowledge of...

Let knowledge grow bountifully like plants in a garden. Given a diagram of a rectangular garden split into plots, scholars determine the area of the entire garden and the areas of the individual plots. As a culminating activity, they...

Get lost in the classifications. Using the backdrop of the Bermuda Triangle, pupils classify it by angle and side measures. They also learn information about the triangle and its history.

Your learners combine their knowledge of real and imaginary numbers and matrices in an activity containing thirty lessons, two assessments (mid-module and end module), and their corresponding rubrics. Centered on complex numbers and...

Trying to understand the vastness of outer space can be quite a challenge for young scientists. Help put things in perspective with this cross-curricular activity as students work in pairs creating scaled models of...

Model hardness testing with a self-designed hardness test. Young scholars rate the hardness of different types of aspirin using the Vicker's Hardness scale. They then relate hardness to the solubility of each aspirin tablet.

With so many math standards to fit into a school year, it can be difficult keeping track of what you have and have not covered. This collection of Common Core checklists allows you to maintain a running record of when each...

Let's paint the town equal parts yellow and violet, or simply brown. Pupils calculate the amount of blue and red paint needed to make six quarts of brown paint. Individuals then explain how they determined the percentage of the brown...

Scaling needs to be picture perfect. Pupils use proportional reasoning to find the missing dimension of a photo. Class members determine the sizes of paper needed for two configurations of pictures in the short assessment task.

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...

Buying a new sofa? Learn how to use the Pythagorean Theorem, as well as algebra and graphing techniques, to determine whether the sofa will fit around a corner (which I'm sure you'll agree is a very important consideration!).

Fourth graders explore unit conversions. They create visual models of measurement units, identify tables of equivalent units and make simple conversions with in a measurement system. Students produce charts that identify units of measure...

Second graders use a meter tape to compare the length of the Mayflower to a basketball court and make homemade butter for crackers. Afterward, all students sit inside the makeshift Mayflower's dimensions and enjoy their Pilgrim butter.

Students examine the importance of good quality safety gear. In this investigative lesson, students will tests various polymers, collect data, and analyze the data to determine which polymer is best for safety helmets. They will design a...

For this areas of triangles instructional activity, learners observe given polygons. They determine the area of triangles, rectangles and compound figures. This one-page instructional activity contains 5 multi-step problems. This...

Sixth graders calculate a light day, light hour, and light minute from the standard of a light year. After establishing the distances, a one meter scale is created to demonstrate the distance between the sun and the planets of our solar...

Students determine the molar volume of hydrogen gas. In this molar volume lesson plan, students find the molar volume of hydrogen produced in a reaction between magnesium and hydrochloric acid. They use a eudiometer to measure the volume...

Young scholars build nets of three-dimensional prisms based on the dimensions they are given for hexagonal prism, triangular prism, rectangular prism. Working in groups, they use their prisms and calculate the Surface Area and Lateral Area.

Students examine gravity, mass, and friction. In this speed and motion instructional activity, students investigate how straight line motion is impacted by gravity, mass, and fiction as they participate in a hands-on activity.

Sew up your unit on operations with decimals using this assessment task. Young mathematicians use given rules to determine the amount of fabric they need to sew a pair of pants. They must also fill in a partially complete bill for...
