This math investigation has kids consider the branch growth of a Mistletoe tree. They use imput tables to determine branch growth per year. Cool way to warm up when it's cold outside.

A good classroom tool is always great to have around. This tool provides learners with an opportunity to view and investigate the properties of quadrilaterals. Each slide contains images of a square as it is dissected into various...

Here are a few well-thought-out discussion questions intended to accompany a probability activity. Learners consider equal chance outcomes under given situations, they investigate those outcomes by tossing a coin 30 times. They analyze...

Look at patterns in bivariate data. Eight sample items illustrate the eighth grade statistics and probability standards. The Smarter Balanced Sample multiple-choice items focus on numerical and categorical bivariate data. The slide show...

The probability is high that these questions will challenge your pupils! The ninth and final installment of the Grade 7 Claim 1 Slideshow series, a set of items assesses the understanding of simple and compound probability concepts....

A few good questions move this lesson right along. Young mathematicians use critical-thinking skills as they learn how to determine the perimeter of various shapes. They determine perimeter first by measuring and adding the lengths of...

Tongue Twisters?!  Create scatter plot graphs based on timing fellow classmates saying tongue twisters.  Then investigate, display, and analyze the relationships based on functions.  Wrap up this activity by making a...

Positioned inside the framework of linear and exponential functions, this lesson is more of an investigation into the effects of changing variables and constants inside an expression. The author takes familiar formulas, those for...

Here is a fine presentation on probability, and the language of probability. Pupils are introduced to the words, impossible, unlikely, likely, and certain. Then, they consider a variety of events, and assign one of the words to describe...

An excellent presentation on calculating area and perimeter is here for you. In it, young mathematicians are given five examples to solve for perimeter, then five examples to solve for area. The final two slides present a word problem...

What are constraints and how can they be represented mathematically? This instructional slideshow provides an explanation and an example of how to translate constraints into algebraic inequalities.

Highlight the process of mathematical discovery for your classes. This lesson examines the development of the Fundamental Theorem of Calculus over time. Understanding the history of the theorem helps create a better understanding of the...

Will this water source support life? Small groups test the chemistry of the water drawn from two different sources. They then compare the collected data to acceptable levels to draw conclusions about the health of the source. The...

Class members learn how to estimate the total costs involved to design and build a bridge by including design, material, equipment, and labor costs. The activity includes a discussion about the trade-off between cost and aesthetics.

How diverse are the benthic organisms found in local streams? Using the information learned in previous lessons on identification of macroinvertebrates and on calculating stream index values, groups determine the health of local...
