How can learners use algebra to solve a geometry problem? Help learners create an equation that shows the relationship between the number of sides of a polygon and the sum of the interior angles. Students are asked to divide the...

Define words with numbers in a fun vocabulary activity. Using words from Hoot by Carl Hiaasen, learners use a grid to match words and their definitions, and to find the magic number that is the same when the numbers are added from...

Incorporate geometry into the solving linear equations lesson plan. Pupils use their knowledge of geometry to write linear equations which reinforces geometry measurement concepts while at the same time providing a familiar context...

One of the basic properties of inscribed angles gets a triangle proof treatment in a short but detailed exercise. Leading directions take the learner through identifying characteristics of a circle and how they relate to angles and...

Uncover the relationship between factoring quadratics and higher degree polynomials. Learners develop their factoring skills through repetition. A comprehensive lesson begins with quadratics and shows how to use the same patterns to...

Young scholars participate in a lesson that investigates Newton's Second Law of Motion. They conduct an experiment of observing balls that are rolled down a ramp. The lesson includes background information for the teacher for preparation...

Polygons — it's all about the angles. Groups work with dynamic geometry software to find the sum of the measures of the angles of various polygons. After finding the information for several polygons, the groups generate a formula that...

Wait, you mean researchers don't all use Wikipedia? Teach your class about intelligent research with a lesson plan about evaluating digital sources. The lesson plan starts with a quickwrite and includes vocabulary exercises and...

Students make a bungee cord. In this potential and kinetic energy lesson, students work in groups to create a bungee cord for an egg. Students evaluate and test their cord. After performing the experiment the students answer...

Students investigate the concepts related to the study of polygons. They specifically look at how angles is related. The lesson includes specific examples and dialogue to be used by the teacher during direct instruction and independent...

As part of their study of Amy Tan's The Joy Luck Club, readers engage in a magic squares vocabulary activity.

In this critical thinking worksheet, young scholars complete problems which require abstract reasoning and logic. They complete logic puzzles involving sums of an array, finding the maximum number of integers under given conditions, and...

High schoolers examine the concepts of balanced forces, unbalanced forces, and resulting net forces. They participate in a force and motion demonstration by pushing students in various directions, and calculating and identifying the...

Students construct a convincing argument that the same amount of fabric is needed for each color of quilt being made in a specific design. They justify the relationship between vertical angles and the sum of the interior angles. Students

You don't have to be an ancient Egyptian to decipher fractions in this activity that focuses on adding fractions with unlike denominators and developing fraction number sense. Egyptians represented fractions differently than we do. They...

This resource sneaks in the math so your learners will be adding and subtracting positive and negatives on a number line while thinking they are mapping out houses. The activity starts by putting houses the appropriate distance away from...

Investigate how similar and congruent figures compare. Learners understand congruent figures have congruent sides and angles, but similar figures only have congruent angles — their sides are proportional. After learning the...

Students use this problem to help them to relate to force vectors: Suspend a meterstick horizontally between two tables. Place a 1kg mass in the middle of the meterstick. Notice the bend of the meterstick. Explain why the meterstick...

Fourth graders examine the purpose of variables and identify the missing variable in open sentences. They observe the teacher solve a variety of problems, complete a worksheet as a class, and independently complete another worksheet. ...

Fourth graders practice adding rice cookies. In this mental math lesson, 4th graders get into groups and call out numbers to each other to add mentally. Students use the rice cookies to show the answer.

In this teaching American history worksheet, students examine a primary source document regarding the Stamp Act. Students discuss their impressions of the document.  

Students investigate net force by building Rube Goldberg contraptions. They build a contraption that has at least 6 steps or moves.

Students use geometry or trigonometry to measure the distance of a far off point. They verify their measurements using a tape measure to check their work.

Second graders solve addition problems without using a calculator. In this addition lesson, 2nd graders solve addition problems by "counting on." Students are taught this specific strategy and given the opportunity to practice.
