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...

Can you prove it? Lead your class through the development of the Side Splitter Theorem through proofs. Individuals connect the ratio and parallel method of dilation through an exploration of two proofs. After completing the proofs,...

Win the war of the worlds! Scholars solve a variety of problems related to an alien invasion. They determine where spaceships have landed on a coordinate map, devise a plan to avoid the aliens, observe the aliens, and break a code to...

Young scholars convert their physical models of a playground from a previous lesson into a map of the playground that includes a scale and key. They examine and discuss examples of maps, view an image to map photo essay, and create a map...

How do you find the lengths of items that cannot be directly measured? The 13th installment in a series of 16 has pupils use the similarity content learned in an earlier resource to solve real-world problems. Class members determine...

Congratulations, you've just hit the word problem jackpot! Covering an incredible range of topics from integers and fractions, to percents, geometry, and much more, this collection of worksheets will keep young mathematicians...

Learners calculate the pixel density of a specific cell phone using the concept of similarity. They use information from the cell phone's website to make their calculations and then compare their results to the posted information.

Tree rings are slightly thicker on the south side of the tree because it receives more sunlight. Part two in a series of five lessons helps learners analyze tree rings to determine the environmental conditions that caused size...

Students create visuals of the effect of a spring scale. In this algebra lesson, students use the navigator to graph the effects created by a spring scale. They draw conclusion from the graph.

Seventh graders watch a video and enlarge and shrink scale by applying proportional thinking. They practice measuring, using percentages, computing area, and problem solving.

In this two-sided confidence interval worksheet, students solve 3 problems to include constructing a confidence interval for a population proportion with a large sample. First, they split the confidence and shad its cumulative are for a...

In this math worksheet, middle schoolers compare the fractions while solving the proportions. They apply the comparisons to the 17 word problems.

Learning about proportions through measuring and mapping distances is the focus of this real-world math lesson that doubles as an activity. Mathematicians complete a course designed to measure and map locations in order to put the...

Seventh graders explore how proportion controls the image of a drawing. They examine a coordinate plane and discuss plotting. Student experiment drawing an object one size, and then drawing an identical object on a different scale.

Young scholars estimate relative size and scale of humans, animals, and objects. They verify their estimations through research and measurement and then draw themselves in proportion to other creatures, both larger and smaller, in a...

High schoolers measure various dimensions of a male and a female dolls body and scale them proportionally to average human measurements. They calculate the appropriate scale factor (magnitude) to enlarge their doll and apply that scale...

Use some similar problems to find side lengths. Pupils learn the definition of similar figures and how it relates to corresponding angles and sides. Using the definition, individuals calculate the lengths of missing sides and practice...

Not all interactives are made equal. Scholars use an interactive balance to explore the concept of equality. They place different objects on balances to determine the number of each object needed to balance the scale.

What's around the block? Or down the street? Ask your pupils to tap into their map skills by drafting the area around their home and school.

Challenge young astronomers to demonstrate their knowledge of the solar system with this fun open-ended science project. Provided with a short list of requirements, students are given the freedom to use their creativity and whatever...

Twelve chapters cover a multitude of math concepts found in the Common Core standards for sixth grade. Each title provides a brief explanation of what you will find inside the chapter—concepts from which you can click on and learn more...

Weathering is not necessarily a result of the weather. Scholars conduct an experiment to explore the effect of surface area and volume on the weathering process. They create their own sugar cube rocks using the same number of cubes—but...

The coal is mined. Now what? Scholars design a coal silo that stores mined earth using at least two different three-dimensional shapes. They calculate the volume, determine the amount of mined earth produced in a day, and find the amount...

Cook up a nice new kitchen. Future designers apply quadrilaterals to design a new kitchen floor. They create a tessellation and determine the area of the pattern. As an added component and real-world application, they must stick to a...
