Review Sheets: Beginning Algebra
This jumbo worksheet contains everything you need to get through Pre-Algebra. Begin with simple expressions, and end with linear functions and polygons. There are multiple problems for each topic to make sure those skills are set.
Curated OER
Discovering a Law of Space Physics
Young scholars use data collected by an astronomer to determine the relationship between the time it takes the planet to orbit the sun and the average radius of the planet's orbit around the sun. Students use trial and error to find the...
Curated OER
Relative Ratios
Learners discover that proportions are made up of equal ratios each containing the same building blocks. They, using the Internet, apply their knowledge of direct relationships and proportions to problems in planetary science.
Curated OER
Resistance in a Wire
Students find the constant of proportionality and apply it to a situation. They use the electrical resistance in a wire as a context for finding the constant of proportionality. In addition, they write an explanation and justification of...
Curated OER
Shadow Chasing
The students compare themselves and their shadows to various objects big and small. Students use their data to set up proportions to solve.
Curated OER
Oval Action Figures
Students discover the basics of figure proportion and create oval figures which show the human body in motion. Artists also study the way the body moves and bends. They see that artists study live models and make many sketches or studies...
Curated OER
WINDMILL POWER
Students study operations with real numbers using mental computation or paper-and-pencil calculations. They judge the reasonableness of numerical computations and their results. They set up and solve proportions for direct and inverse...
Curated OER
Scaling Down Art
Students change the scale of a work of art using ratios, percentages, and proportions. While this is technically an art lesson, there is quite a bit of mathematics involved in converting to the correct scale.
Curated OER
Paying for Crime
Learners participate in activties examining ratios and proportions. They use graphs to interpret data showing the government's budget for prisons. They present what they have learned to the class.
Curated OER
Rates And Unit Price
In this rates and unit price worksheet, students problem solve and calculate the answers to ten word problems and mathematical equations dealing with ratios, proportion and missing values.
Curated OER
Measurement of Volume
Young scholars measure the volume of a clear container using a candle and sand. In this measuring volume lesson plan, students time how long a candle stays lit in a clear glass container. They fill it with sand and find the volume and...
Curated OER
The Composition of Soil
In this composition of soil worksheet, students study the make-up of soil by identifying the amount of air in the soil, the amount of water in the soil, the size of the mineral grains in the soil and the proportion of humus in the soil....
Curated OER
Indirect Measurement, Surveying Trigonometry
Students measure distances using indirect measurements. In this geometry lesson, students apply proportion and ratios to measure heights of different objects. They differentiate between direct and indirect measurements.
Curated OER
Creating Realistic Faces
Students explain that, in order to create realistic faces, artists study live models, use mathematics to explain correct proportion, and practice by making sketches. They create a self-portrait using these principles.
Curated OER
Gesture Drawing
Students investigate the use of proportion using gesture drawing as the subject matter. They create a painting using the elements of art and principles of design.
Curated OER
Elections
Students examine why and how elections are conducted in Australia. They compare first-past-the-post, preferential and proportional systems of voting. Students brainstorm the names of elected representatives in the current federal...
Curated OER
Balobbyland City Planners
Students create a mini city using proportions that fit a model human they construct using tin foil. They plan the city including a library, sports arena, living spaces, parks and businesses. When constructing the paper buildings, they...
Curated OER
Percentages in Word Problems
Eighth graders, after brainstorming all the places they see percentages in every day life (sales, basketball, grades, etc.), calculate percentages from bases and parts in word problems. They review their notes together on percentage...
Curated OER
It's Greek to Me!
Students explore Greek Mythology. In this Greek Mythology unit, students read myths, pantomime vocabulary words, practice research skills, create city-states, and demonstrate knowledge of ratios and proportions. This unit includes many...
Curated OER
Indirect Measurement
Learners measure and apply their knowledge of proportion to solve problems. In this geometry lesson, students measure using a meter stick, small mirror and measuring tape. They compare and contrast their measurements to objects outside...
Curated OER
MASS
Students distinguish between weight and mass. They examine how in oscillations of a mass against an elastic spring--in the absence of gravity, or in horizontal motion--the length of the oscillation period is proportional to the square...
Curated OER
Stream Ecology In Wisconsin and Puerto Rico
Students identify the different types of water and explain in what proportions they exist on Earth. They identify and correctly label the parts of the water cycle and how these parts interact with each other. Students identify the...
Curated OER
Comparing Ratios
Students solve problems using ratio and proportion. In this math comparison instructional activity, students identify methods used to solve and compare ratio and proportion in the real world. They apply criss cross multiplying to solve...
Curated OER
Radian Measure
Young mathematicians identify central angles, arcs and radius of circles in this pre-calculus lesson. They identify the proportion of the circle based on its radius while they convert between degrees and radians measurements.
