The Road to Proportional Reasoning
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...

Go Far Cars Ramp: A Basic Ramp with Four Height Settings
Precise measurements make the job easier! One of the challenges when using an inclined plane for testing comes from pupils not using exact measurements. They often rely on books that slide or different ramp lengths when experimenting. By...

The Distance from a Point to a Line
What is the fastest way to get from point A to line l? A straight perpendicular line! Learners use what they have learned in the previous lessons in this series and develop a formula for finding the shortest distance from...

Making Metric And Customary Rulers
Students create a ruler for the purpose of measurement using the standard and metric systems. The rulers are of different lengths and are compared to one another. Then students make conversions of different lengths using both systems of...
Curated OER
One, Two, Three...and They're Off
Students make origami frogs to race. After the race they measure the distance raced, collect the data, enter it into a chart. They then find the mean, median, and mode of the data. Next, students enter this data into Excel at which time...

Leaving on A Jet Plane
Students create an airplane by listening to directions. They also to measure the pieces for the airplane and compare and contrast their test flights.

Similar Triangles and Proportions
Pupils investigate similar triangles and proportions as they make conjectures about the length of sides of similar triangles. For this lesson, have your class construct similar triangles using Cabri Jr so that they share a common vertex.

Right Triangles
In this right triangles learning exercise, 10th graders solve and complete 14 various types of problems. First, they find the perimeter of the isosceles trapezoid shown. Then, students find the measures of each marked side of a right...
Curated OER
Similarity
In this similarity worksheet, 10th graders solve and complete 14 different types of problems. First, they refer to each drawn figure given that the lines are parallel. Then, students find the length of each segment listed. In addition,...

Classifying Triangles
In this classifying triangles worksheet, students explore given lengths or angle measurements and then classify each triangle as isosceles, scalene or equilateral. They also determine if the triangle may be right, acute or obtuse. This...
Curated OER
Quadrilaterals
In this solving quadrilateral word problems worksheet, students draw figures to identify quadrilaterals, use angles to find the ones missing, and explain classification. Students solve six problems.

Tired Weight
You don't need a scale to determine weight. This activity provides a way to use the concepts of air pressure and surface area to determine the weight of a vehicle by calculating the amount of weight each tire supports.
