Students observe and solve examples of corresponding angle postulates, alternate interior angle theorems, and exterior and consecutive angles. They complete the Determining Angle Measure With Parallel Lines worksheet.

Students calculate angle measure for triangles and complementary/supplementary angles. After a lecture/demo, students utilize a worksheet imbedded in this plan to gain practice.

In this Algebra I worksheet, 9th graders use the computer program Understanding Equations to investigate subtractions of integers and algebraic expressions.  Students then complete the four page off computer worksheet which contains...

Students sort objects based on one characteristic. They define the term "attribute" and give examples of attributes of objects. Students explain their reasoning for sorting objects into groups.

First graders sort toys by various attributes. They, in groups, sort toy vehicles by color, size etc. and then explain how they chose to group the toys. They write, draw or dictate an explanation of their sorting methods.

Students demonstrate knowledge of sorting and classifying by color as they sort gummy bear candies.

This lesson involves live ladybugs. Students view two containers of water and take the temperature of each. They construct a graph on chart paper to compare the two containers. Students speculate which water sample the ladybugs will like...

Students explore why Antarctica is so important to the planet. They investigate the physical characteristics. Students create their own unique treaty of governance for Antarctica and discuss how laws are enforced in Antarctica.

Young scholars explore acids and bases. They experience the sour taste of acids and the bitter taste of bases by tasting substances such as chocolate, lemon juice, and baking soda. in addition, they complete a worksheet for individual...

For this shapes worksheet, students are asked to "colour" all of the triangles they find on the page. There are 10 shapes on the page and 4 are triangles. The second page contains suggestions for teachers on activities with 2-D shapes.

In this congruent triangles and rectangles worksheet, students solve 6 word problems where they identify whether triangles and rectangles are congruent, and construct triangles. Students must explain their reasoning and prove each answer.

Tenth graders practice adding, subtracting, and multiplying matrices. After completing and reviewing bell ringer problems they review homework from night before and discuss any questions. Students are introduced to new matrix...

Students calculate the area of triangles using a variety of materials including computer applets.

Fourth graders find bugs represented on a grid and then identify their name and physical characteristics that provide a picture of the bug using imagery.

Second graders count by 5's to 100. In this math instructional activity conducted on the 100th day of school, 2nd graders use picture stamps in the KidPix program to count by 5's and get to 100.

Students investigate the law of reflection by using mirrors. In this physics lesson, students operate a robot using IR controllers. They explain the path of light as it reflects through a surface.

Eighth graders engage in a lesson plan that is concerned with examining two dimensional figures with different properties that include circles, triangles, queadrilaterals, etc... They identify the types of figures that is identified as...

Tenth graders answer a variety of problems based on similar triangle and learn about the rule of thumb. They will test the rule of thumb by estimating the distance to an object in the classroom.

Sixth graders estimate the measurement of angles and then measure the exact distance using an angle ruler. In groups, they explore shapes and recognize the characteristics acute, obtuse and right angles. Students sketch required shapes,...

Students try to figure out the strategies to the game Noughts. Students logic must play a part in the process of the game. Students apply the symmetries of regular polygons. Students devise ways to critically follow a chain of reasoning.

Students independently investigate the Pythagorean Theorem. They are given a set of triangles that involve whole number Pythagorean Triples. The main focus of the lesson is exploration rather than discovering the Pythagorean Theorem.

Fourth graders, in groups, experiment with density and the displacement of water by creating and designing their own boats and seeing which boat holds the most centimeter cubes without sinking..

Students are introduced to the problem and brainstorm ideas for approaching the problem and keeping track of what has been done. They work in pairs and share their answers, explaining their reasoning.

Students are introduced to the problem. They brainstorm ideas for approaching the problem and keeping track of what has been done. Students work on the problem in pairs to discover what strategies might help to find the answer.
