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.

Investigate the Remainder Theorem in this algebra lesson. Explore the relationship between the remainders of polynomial division and the function. Each of the four problems gets progressively more complicated. This might be a great...

Help online friends Digger and Sprat from the BBC series to solve math problems! In a series of activities, your class will use data sets to calculate measurements, averages, means, and probabilities. The class completes worksheets and...

Tenth graders explore the Greenbriar Resort. In this budgeting lesson, 10th graders plan and calculate the cost of trips from their home to the Greenbriar Resort.

Help pupils explore estimation. They will make estimates and discuss when you might use an estimate. Then they discuss if their estimates are reasonable.

Pupils participate in repeated reading activities to improve their fluency after listening to the teacher model fluent and non-fluent reading. They work with a partner to complete repeated reading of sentences and books while being...

Learners explore the concept of piecewise functions. In this piecewise functions lesson, students graph piecewise functions by hand and find the domain and range. Learners make tables of values given a piecewise function. Students write...

Middle schoolers calculate gear ratio as they solve word problems. They discuss and find slopes as they relate to real life. Additionally, they hey use ratio and proportion to make predictions and solve problems.

Algebra learners must know how to use rational numbers to approximate irrationals. This resource asks participants to decide which number is larger without using a calculator. It makes a great exercise to use as a five-minute transition...

Students use logical arguments and inductive reasoning to make or disprove conjectures. After observing a teacher led demonstration, students discover that the deductive process narrows facts to a few possible conclusions. In groups,...

Young mathematicians calculate the area of rectangles and squares. In this geometry lesson, learners are grouped in pairs and use geoboards to construct rectangles. They calculate the area of the figure by counting the number of square...

Underclassmen create a cone-shaped landform and then draw a contour map for it. Then they examine a quadrangle (which was easily located with an online search), and relate it to what they experienced. The accompanying worksheet is...

Students use the Internet to find out about eating disorders and maintaining a healthy weight. In this eating disorders lesson, students identify eating disorders such as anorexia and bulimia and discuss complications. Students discover...

View a PBS video entitled Horatio's Drive and explore Horatio's Ratios. Collaborative learners form groups to use Mapquest to determine distances covered. They generate the mathematical averages, ratios, and rates in order to calculate...

Students gather appropriate information for simple statistical analysis. Then they will calculate probability working with a piece of literature that makes this lesson ideal for teaching across the whole curriculum.

Fourth graders use inductive reasoning to find algebraic patterns in geometric figures. They use technology (i.e., calculators, computers) and manipulatives to discover number patterns involving geometric concepts. They solve concrete...

Third graders talk about all the various ways they get to school. They make a list of all the bus numbers that the students use. They also list all the other methods of transportation used and solidify a hypothesis.

Upper elementary and middle schoolers work with the concept of probability. They are introduced to the concept of chaos. Learners graph and analyze using a line plot, work with mean, and are introduced to the concept of variance.

In these math lesson plans, students discuss how math problems are written to reflect real-world situations. They complete an online Math Hunt using specific web tools, and work individually to create their own Math Hunts....
