Pi as a Ratio
Eighth graders measure the circumference and the diameter of circular objects and record the measured values of the circumference and the diameter in a table. They then record their measurements in centimeters and use their data to...
Curated OER
Using Circumference
Learners participate in a lesson that covers the concept of finding the circumference of a circle. The teacher covers relevant vocabulary with the students. They work in groups to measure objects and calculate the formula to find the...
Curated OER
Around We Go
Fourth graders investigate a range of circles, each with a different radius, diameter and circumference and assemble this information in their search for relationships.The measurement of circles and the relationships to be found within...

Length and Weight
In this measurements worksheet, students complete the 9 sets of length and weight measurement activities to help them learn measurements.
EdHelper
Length and Weight
For this measurements worksheet, students study the illustrated pictures in the 8 sets of problems. Students compare the pictures by length or weight.
Curated OER
Nonstandard Units
For this units of measurement worksheet, learners learn to use nonstandard units of measurement to measure the items in each problem.
EdHelper
Weight
In this weight measurements activity, students identify each picture and then estimate how much the object weighs. Students circle the answer in ounces and pounds that gives the best estimate for the 9 problems.
Curated OER
Robot Lesson
Students identify and use descriptive writing and measurement terms to describe a student-created robot. Then they construct robots of materials available and then use AlphaSmarts or Danas to describe the robot using only the dimensions....

Area graphics for 7th graders
Young scholars randomly select dimensions for three geometric shapes (square, right triangle and circle). From the graphs they compare and contrast the graphical results of each shape.
Curated OER
Graph Groups
In this mathematics worksheet, learners solve a number of problems by counting each shape and graphing the amount to the right in height. Then they circle the shape that appears the most often on the sheet.
