Classifying triangles lesson plan

remarkable, very amusing idea Yes, understand you..

In our Triangles lesson plan for gradesstudents learn to differentiate between and identify the four types of triangles. Students also practice drawing each type. Our Triangles lesson plan for grades prepares students to identify the four types of triangles and distinguish between each type. Students are asked to draw each type of triangle and recognizing the types of triangles used for buildings and other structures and objects. Students are also asked to identify the type of triangle by its written description and by the angles it has.

At the end of the lesson, students will be able to identify the four types of triangles and distinguish between each type. The students will be able to draw each type of triangle and recognize the types of triangles used for buildings and other structures and objects. Skip to content.

Wish List.You'll be using Sketch 1 of this file which has three different types of triangles - scalene, isosceles, equilateral. Each triangle type has a different colour pink for scalene, red for equilateral, blue for isosceleswhich allows you and the students to refer to the triangles without having to introduce their formal geometric names.

Sketch 1 is intended to help the students attend to the similarities and differences between the three triangles. While initially very similar looking, these triangles behave very differently under dragging. After the initial discussion about the static triangle images, have one student explore dragging the pink triangle. Have the other students act as detectives, noticing what changes when the triangle is dragged and what stays the same. Now have a student explore trying to overlap the blue triangle onto first the red triangle and then the pink triangle.

Have several students explore this - they need to be convinced that the blue triangle can't overlap the pink triangle.

Objectives Big Idea — We can describe, measure, and compare spatial relationships. Properties of movement: - Students may notice that some points can be dragged directly and move freely, that some cannot be grabbed but may move by means of another point.

Activity — Whole Group 1. Ask: "What kinds of shapes do you see on the screen? Ask: "Can you make the triangle really long and skinny?

Start off with a game of Simon Says. Direct your students to imitate you making three different angles with your arms: right angle one at 90 degreesan acute angle one at less than 90 degreesand an obtuse angle one greater than 90 degrees.

As you make your angle and the students imitate you, tell them the definition of each angle you make. For example, "Simon says make a right angle; this angles is at 90 degrees.

Hand out and preview the Sorting Triangles worksheet and observe the shape labeled 9 in the shapes box. Have students review the angle categories, turn to a neighbor and share which category triangle 9 belongs in. Allow for students to determine that it is an obtuse triangle and place the number 9 on the proper section of the diagram where obtuse does not overlap with another category.
