A fabulous set of examples and problems that introduce basic trigonometry concepts, this packet is set apart by the care it takes to integrate both radians and degrees into the material. After defining radians, the author demonstrates...

Who knew running a greenhouse required so much math? Amaze future mathematicians and farmers with the amount of unit conversions, ratio and proportional reasoning, and geometric applications involved by having them complete the...

Investigate how similar and congruent figures compare. Learners understand congruent figures have congruent sides and angles, but similar figures only have congruent angles — their sides are proportional. After learning the...

Start a trend by using blirts and gorks as your standard unit of measures. The activity asks learners to take a known measures of blirts and gorks and develop a conversion ratio. Individuals use both perimeter and area measures of...

Is that drawn to scale? Capture the artistry of geometry using the ratio method to create dilations. Mathematicians use a center and ratio to create a scaled drawing. They then use a ruler and protractor to verify measurements. 

What does it mean for a quadrilateral to be cyclic? Mathematicians first learn what it means for a quadrilateral to be cyclic. They then investigate angle measures and area in such a quadrilateral.

How do you solve for an unknown angle? In this sixth installment of a 36-part series, young mathematicians use concepts learned in middle school geometry to set up and solve linear equations to find angle measures.

Learners study a way to quantify the process of photosynthesis during a given time using the Elodea plant. They design a hypothesis that they test in the hands on activity. They compare the amounts of photosynthesis that occur during low...

Looking for an excellent instructional activity that incorporates math, science, and technology? Groups of three students use a viewing tube to perform an experiment, and discover how to organize their data into an Excel...

Here's a clever math worksheet that has learners measure their hand span, foot length, come up with a ration, then use that information to figure out the hand span, and foot length of basketball giant Shaquille O'Neal. A good activity!

Over the course of 18 problems, learners identify angles as complementary, supplementary, vertical or adjacent. They name relationships in angles such as alternate interior, corresponding, and alternate exterior angles. They apply the...

In this measurement worksheet, students convert centimetres to millimetres and millimetres to centimetres. Normal objects are used for examples of measurement.

In this decimals worksheet, students solve 18 different types of problems that include both decimals and non-decimals. First, they subtract the measurement problems given both in metric units and in US units. Then, students subtract the...

For this quantitative data worksheet, pupils compute measures of central tendency, draw vertical line diagrams, and compare collected data. This 23-page worksheet contains approximately 100 multi-step problems. Explanations and examples...

Students demonstrate how to tell time using an analog clock. For this time measurement lesson, students read the book Clocks and More Clocks and use analog clocks to demonstrate the time that the teacher called out.

Upper graders practice using measurements by solving conversion problems. There are given different time or measurement increments and must convert them to a larger or smaller increment. They also utilize a calculator and conversion...
