Systems of parallel lines have no solution. Pupils work examples to discover that lines with the same slope and different y-intercepts are parallel. The 27th segment of 33 uses this discovery to develop a proof, and the class determines...

Graphing by hand does have its advantages. The 19th installment of a 35-part module prompts pupils to use skills from previous lessons to graph exponential and logarithmic functions. They reflect each function type over a diagonal line...

Can you graph your story? Keep your classes interested by challenging them to graph a scenario and interpret the meaning of an intersection. Be sure they paty attention to the detail of a graph, including intercepts, slope,...

Inequalities: when one solution just doesn't suffice. Individuals learn to write inequalities in real-world contexts and graph solution sets on the number line. All inequalities in the lesson are of the form x < c or x < c.

Scholars first complete an assessment task on writing linear equations to model and solve a problem on a running race. They then take part in a card matching activity where they match equations and graphs of lines to diagrams of fluid...

Here is a great lesson on constructing line graphs. Learners identify common characteristics of birds, ants common needs of all living things. They also write a story from the perspective of an ant or a bird that has lost its home and...

Combine linear equations and a little creativity to produce a work of art. Math scholars create a design as they graph a list of linear equations. Their project results in a stained glass window pattern that they color.

Is American growing fatter? Scholars begin with a mini instructional activity on reading charts and graphs using information about Human Body Fat in United States. They then transfer what they learned to charts and graphs using ...

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. 

Discover how trend lines can be useful in understanding relationships between variables with a lesson that covers how to informally fit a trend line to model a relationship given in a scatter plot. Scholars use the trend line to make...

Can you solve an equation graphically? Absolutely! This Algebra II lesson makes the connection between solving an absolute value equation and graphing two functions. Graphing absolute value functions is presented through the process of...

Parallel parking might be difficult, but finding parallel lines is fairly simple. In this lesson, learners first complete an assessment task involving parallel and perpendicular lines in the coordinate plane. Individuals then take part...

The key is ... After a day of instruction on key features of graphs, groups create a poster and presentation on the key features of their given function graph. The resource provides an extension activity of "telephone" using...

Young mathematicians first graph a series of quadratic equations, and then investigate how various parts of the equation change the graph of the function in a predictable way.

Fifth graders collect data and use charts and line plots to graph data. Through class surveys, 5th graders collect data concerning a particular subject. They graph their data using a line graph. Students make inferences and predictions...

Young artists divide a piece of graph paper into sections using rectangles, squares, and triangles. They then fill each section with patterns of shape and color. Elementary graders describe how their patterns are organized. Secondary...

Students are given three choices of food. They then decide on their favorite and predict what the class's favorite food will be. After the teacher enters the data into the computer, students gather around the computer to view the...

Seventh graders examine their school performance through self-assessment of strengths and weaknesses. They construct a line graph, plotting all courses and achievements. Students use graph paper and colored pencils for each activity. If...

Providing both review and practice problems, this worksheet prompts students to answer five questions having to do with slope, tangents lines, graphing, the Squeeze Theorem, differentiable functions and derivatives. This activity could...

Activate the strengths of your visual learners using an informative lesson. In the 15th installment of the series of 28, pupils graph their solutions on number lines to create a visual representation of solutions. Problems presented as...

What do those points on the graph mean? The 10th instructional activity in a series of 22 presents proportional relationships as graphs. Class members interpret various points of the graph — including the origin — within the context of...

Sixth graders review the different types of graphs (bar, line, pictograph) They predict the data set they can garner several boxes of conversation hearts. Students record their data using an Excel spreadsheet. They create a graph based...

The Black Death epidemic is responsible for more than one million deaths in the United Kingdom. An inquiry-based activity has young scholars explore the rate of disease spread. They then analyze graphs showing data from epidemics such as...

Give your mathematicians this set of data and have them create a dot plot, then find mean and median. They are asked to question the values of the mean and median and decide why they are not equal. Have learners write their answers or...
