Why is that graph wider? Pupils learn about stretching and shrinking graphs of square root, absolute value, cubic, and quadratic functions. They study both vertical and horizontal stretches and shrinks in addition to reflections. 

We know that sample data varies — it's time to quantify that variability! After calculating a sample mean, pupils calculate the margin of error. They repeat the process with a greater number of sample means and compare the results.

As part of an investigation of transformations of exponential functions, class members use Newton's Law of Cooling as an exponential model to determine temperature based on varying aspects. The resource makes comparisons between...

What linear equation will fit this data, and how close is it? Through discussion and partner work, young mathematicians learn the procedure to determine a regression line in order to make predictions from the data. 

Define the terms domain, range, function, vertical limit test, and linear function notation with your class. They can then, graph several equations applying the vertical line test to determine which are and which are not functions, write...

Mathematicians determine the solutions of a quadratic function by looking at a graph. They use the quadratic formula to solve quadratic functions on their Ti-Nspire.

students emulate a real world problem and model it with mathematics working in a small group. Observe and facilitate discussion as the groups use various strategies, such as (graphs, brainstorming, tables, and dialogue.

Students apply the concepts of an event occurring to playing a game. In this probability lesson,students differentiate between experimental and theoretical probability.

Have your class practice measuring the perimeter of various objects using this resource. Fifth graders place various-sized polygons in order (from largest to smallest). They use non-standard measuring tools to estimate the distance...

Students identify the maxima and minima of quadratic functions. After a teacher explanation and demonstration of quadratic functions, students solve quadratic equations and graph the solution to find the maxima and minima of each...

Students view a video that reviews Mendelian genetics. They discuss the Hardy-Weinberg Law and use Popsicle sticks to simulate genetic variations and ratios in offspring.

Young scholars investigate systems of linear inequalities as they apply to an area of land. They practice graphing systems and determine if a point lies in the solution. 

Investigate arithmetic and geometric sequences by using a graphing calculator to determine if a sequence is linear or exponential.

Students graph families of equivalent fractions and compare them by observing the slope of the line formed by each fraction family. They place fractions in ascending order by comparing the slopes of each line after several families of...

Students investigate the concept of the Pythagorean Theorem for geometry by using word problems. The challenge is for them to translate the words into the right measurements for a triangle looking for the longest side known as the...

Students investigate the concept of multiplying fractions and use the inverse for doing division. They practice working the problems with scaffolding provided by examples with the teacher. The link is made to real life with the...

Fifth graders study place value. After forming teams, they play a game called, "Who Can Line Up the Number." Students observe numbers in expanded form and place representative digits in the correct order.

You know that liquid nitrogen turns into a gas at room temperature. Place some in a two-liter bottle for a physics demonstration of the ideal gas law. Beware, however; this is a dangerous demonstration! Not to mention that you may not...

Young scholars explore linear functions in a crime solving context. They collect and analyze data using linear equations, then interpret the slope and intercepts from a linear model.

Learners investigate quadratic equations as they use a CBR to collect and analyze data regarding a bouncing ball. Pupils explore different methods for determining the equation of the parabolic path including quadratic regression and...

Students use musical instruments to create simple patterns. They, in pairs, come to the front of the classroom and create a pattern.

Students review the principles of graphing linear functions. They discuss plotting points on a coordinate plane, solving using a table, and then graphing. Students solve problems and determine the slope of the line, y-intercept and if...

Students observe models of fractional parts. After writing the definitions of percent, part and whole, students use the calculators and computers to solve problems. Individually, they complete assigned problems where the convert the...

Sixth graders perform the Order of Operations. Given various story problems, groups of students solve equations requiring division, multiplication, parenthesis, exponents and other mathematical processes. They discuss the order of...
