Students will examine solids to determine which has the least surface area. They will also understand the use of units, square units, and cubic units. There is also the teaching and application of geometry formulas to perform calculations.

Pupils complete activities to learn notation and uses for positive and negative numbers. In this number system lesson, learners play a game similar to Jeopardy to learn how to solve problems with positive and negative numbers.

Seventh graders practice combining decimals and fractions to find sums which are either greater than 4 or less than 5. Students first approximate the value of each fraction and decimal, then they look for combinations to fit the guidelines.

If you have or can create a set of tiles, numbered one through eight, then you can implement this hands-on lesson about probability models. Individuals draw a tile from a bag, record its number, and then return it to the bag. They...

Young scholars will display the first five rows of Pascal's Triangle and discuss in their groups what patterns they see in the rows of numbers. They will give responses and discuss that these numbers form what is called Pascal's Triangle.

Students explore solving addition and subtraction problems. They solve real life problems. Students participate in a simulation activity to find the missing addend. They demonstrate adding and subtracting whole numbers.

Seventh graders explore number sentences using a variety of strategies making each equation a true sentence. Students examine strategies such as patterns, trial and error, working backwards, and related problems. In groups, 7th graders...

What special relationships exist in right triangles? In the high school performance task, learners investigate Pythagorean triples. They then determine rules for the perimeter and area of right triangles given the shortest side.

Tenth graders identify the trigonometric ratios for right angled triangles. Through independent investigation, they discover the constancy between the ratios of any two sides of similar triangles. In an alternative method, 10th graders...

Students investigate integers and solve problems using integers. In this algebra lesson, students solve problems to help improve speed and accuracy of mental math. They develop a deeper knowledge of the way integers are used on a daily...

First graders investigate numerals and size by ranking different numbers based upon value. In this number sense lesson, 1st graders practice using the terms smaller, larger, less and more in order to organize numbers on a number line....

In this investigating slope worksheet, students use their graphing calculators to graph equations of a line with negative and positive slopes. They observe differences between the positive and negative slopes and write a rules based on...

In this investigating scale of model trains worksheet, 6th graders solve one ratio problem for trains of three different scales.

In this math worksheet, students complete a 4 part chart about the addition of odd and even numbers. Students add 5 problems for each: odd plus odd, even plus even, odd plus even. The last part of the chart is for students to write the...

Students examine how Earth's rotation causes daily cycles in solar energy using a microset of satellite data to investigate the Earth's daily radiation budget and locating map locations using latitude and longitude coordinates.

Young scholars design their own playground equipment. In this design instructional activity, students take pictures of equipment they like and make a class pictograph of their favorite ones. They investigate the design, research...

As part of an investigation of transformations of exponential functions, class members use Newton's Law of Cooling as an exponential model to determine temperature based on varying aspects. The resource makes comparisons between...

Investigate the Fundamental Theorem of Algebra and explore polynomial equations to determine the number of factors, the number of roots, and investigate multiplicity of roots.

Manufacturers' claims may or may not be accurate, so proceed with caution. Here pupils use statistics to investigate the M&M's company's claim about the percentage of each color of candy in their packaging. Through the activity,...

Investigate the area and perimeter of polygons in this geometry lesson plan. Young geometers use grid paper to draw a quadrilateral and calculate its area and perimeter. They also read The Greedy Triangle to identify the changing shape...

How sustainable are cell phones? Throughout the unit, learners explore the issues around cell phones concerning sustainability. Class members take a graphical look at the number of cell phones across the world using a box-and-whisker...
