Radius, Diameter and Area
Learners identify the radius and diameter of a circle. For this geometry lesson, students calculate the volume and area of a cylinder and circle. They relate the circumference of a circle to Pi.
Mathematics Assessment Project
Sampling and Estimating: Counting Trees
Your task today: count all the trees on a tree farm. To complete the assignment, learners first estimate the number of trees on a tree farm using random sampling. To improve their own response they then evaluate provided...

Why Are Cells So Small?
Students examine the relationship between cell surface area and the ability of materials to diffuse through a cell. They participate in an experiment in which they determine which materials diffuse easier than others. They complete...
Curated OER
Perimeter and Area of 2D Shapes
Students find the perimeter and area of circles, triangles, and rectangles. For this perimeter and area lesson, the teacher gives students formulas for each shape and measurement and works through examples on the board. While no creative...

Teaching and Learning Through Objects
Students identify and interpret the function, usefulness or utitlity, form, beauty or aesthetics, and meaning, context or story, of objects and how they learn new skills and make things that they learn traditionally, by observation and...
Curated OER
Prints and Outlines
Learners determine the area of two objects by superimposing one on the other. They compare and order the area of different shapes by covering a larger shape with similar smaller ones. They complete these activities as different stations.
