Amazing Circle Number 2

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...

Deepen the fractional number sense of young learners with this introductory lesson on equivalent fractions. After completing a short warm-up activity, children go on to work in pairs using fraction circles to complete a table of...

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...

Put pi to work. The video provides the formulas for the circumference and area of circles. Using the formulas, the presenter shows how to distinguish the two using units. The discussion leads to the second formula for finding the...

Understanding the basic of circles is as easy as pi. The resource introduces the definition of a circle along with its dimensions, circumference, diameter, and radius. Using graphics, the video shows the approximation of pi and how to...

Use a number line to show your learners the relationship between two negative numbers. The number line allows them to visualize which number is greater and all the possible answers that are less than that number. Introduces the topic of...

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...

Take geometry into the real world! You'll find just about everything you need for a fun group project reinforcing terms such as: quadrilateral, parallel lines, hexagon, circumference, vertex, acute angle, polygon, and many more. Of...

Measuring angles is a mysterious task. What do those degrees mean? A clock is used to show what each angle looks like on a circle as the hands move around to mark time. The lesson explains that rays are just like the hands of a clock,...

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...
