Amazing Circle Number 2

Two pies are displayed and your bakers or mathematicians must compute the area of each. The answers to this straightforward task are printed at the bottom of the activity so that learners can check their own work. If you white them out...

Fifth and sixth graders review three steps to help them draw two dimensional views of solid figures. They practice by drawing the top, front, and side view for the figures of stacked cubes, pyramid, and cylinder. Learners review two...

Let your geometers use a calculator, or not, to complete a worksheet that provides eight practice opportunities for finding the area of circles and shapes that include circles or parts of circles. Two of the problems provide unique...

What does this pie chart mean? Once scholars can analyze a circle graph on a basic level (i.e. "Most people prefer cats"), it's time to delve deeper into it. They examine two graphs here, and are given the total number of participants...

The method of converting a mixed number to an improper fraction is fully explained in this video. Sal completely details how and why one is able to convert a mixed number. He uses multiple colors and drawings to demonstrate the...

So you know the circumference of a circle but not the radius. This tutorial shows you two different formulas commonly associated with circles, determines which formula to use, then puts the formula to work. You'll have no problem...

Need an activity that brings your class' understanding of the area formula full circle? The second installment in a two-part series involving geometric calculations further develops the young mathematician's measurement, approximation,...

Solving for circumference is an easy as one, two, pi! Show your learners what pi is and how to use it in an equation. This second video in a series uses the circumference and the radius as a ratio to show that 3.14 is a constant in these...

An interactive assignment displays two example angles to teach how to measure them. When you click on the angles, a protractor appears! As practice, learners view a set of angles, estimate the size of each, and then enter the degrees in...

Two given inequalities and you need to find the union. What is the union? Well, it just means that you need to show the graphs of the given inequalities on the same number line. Keep in mind, less than, greater than, and equal to, and...
