Students solve problems with slopes. In this algebra lesson, students identify the slope of a line and relate it to the rate of change.  They graph their lines on the TI and observe changes in the lines.

Your learners will get lots of practice calculating simple and compound interest by the end of this lesson. Simple explanations and examples lead learners through the concepts and steps of calculating simple and compound interest...

Setting financial goals is a common occurrence in middle school that your learners can practice using this activity. They will be able to solve for how many hours Seth needs to work to save up for a skateboard, helmet, and trip. The...

Exponential growth is modeled by learners as they analyze and interpret the data presented in this real-life scenario centered on the destructive invasion of the Giant African Land Snail. Learners get a touch of history and practice...

Does the number of calories you eat affect the total time you sleep? Young mathematicians tackle this question by collecting their own data and making comparisons between others in the class through building scatter plots and regression...

The introduction to the lesson mentions a sailor's limited capacity to store drinking water on his ship. Pupils then set up an overnight experiment to remove freshwater from salt water by distillation. There is a math and map activity to...

Identify the length, width, and height of prisms. Critical thinkers calculate the volume of prisms given small amounts of information. They derive the formula given the length, width and height.

In this exploring similar polygons worksheet, 10th graders solve 9 various problems that are related to similar polygons. First, they define similar and the symbol used to identify similar to another. Then, students find the measurement...

Students make, read and interpret circle graphs.

High schoolers differentiate between similar and congruent triangles. In this geometry lesson, students identify the angles of triangles using the similarity theorem. They apply concepts of triangles to the real world.

Students explore the concept of similarity and congruence. For this similarity and congruence lesson, students identify and verify whether or not two figures are similar, congruent, or neither. Students use postulates and theorems such...

Students explore the concept of similarity and congruence. In this similarity and congruence lesson, students cut out strips of paper and form a triangle. Students try to prove that their triangles are congruent using the SSS theorem of...

Students practice how to calculate volume using mummy cases. They measure using ancient Egyptian, U.S., and metric systems. They explore how to convert measurements into different systems, and discuss ratios.

Sixth graders practice the conversion of percents and fractions. They focus on the fact of both fractions and percents are part of a whole. In the independent practice the students also work with solving proportions.

Students calculate the size of a mummy case and its contents using ancient Egyptian measurements.

Fifth graders observe and demonstrate the meaning of percents by creating a new deck of fifty-two cards. They meet a specified criteria, with a specific percent of the cards being prime numbers, eight's, multiples of five, face cards,...

Students view a quicktime video of basketball players going from Atlanta to Springfield, Mass. In this scaling lesson, students use a map to calculate the distance of the trip and the length of travel time. Students apply ratio and...

Compose and decompose sets of 13 and 14 and compare sets of each with your little learners. They use objects to construct sets of 13 and 14, record their answers, and compare sets in several different ways.

Future environmental scientists compare data from two different conservation strategies. Alone this lesson is sufficient, but as part of the Exploring Biomes unit produced by the Arizona Fish and Game Department, it becomes top-notch. 

Young scholarsare introduced to the Pythagorean Theorem by exploring right triangles and the squares built on each side. They apply the Pythagorean Theorem to real-world problems. Students u se informal and nonformal arguments of proof...

Students discover the relationships of the lengths of the sides of right triangles and right triangles using a series of drawings on dot paper. They investigate and solve problems of standard (customary and metric units) and non-standard...

Seventh graders explore estimation, measurement, and probability. Students conduct surveys and create charts & graphs. They study the history of chocolate. Students design their own magazine advertisement or create a script for a...

Using food as a manipulative is one of the best ways to incorporate hands-on learning in the classroom. This hands-on approach allows young mathematicians to compare, order, and identify fractions with the use of Twizzlers® and...

Upper graders use the properties of right angle trignonmetry to measure objects such as the school flagpole. They solve real world problems using these properties.
