  TRIANGLE PUZZLE Counting triangles with in the  particular pattern of Triangle How many possible triangles are in the above figures Formula to count number of triangles like above particular pattern type of Triangle where  “n”  = number of unit triangles in a side Note  : Consider only integer part from answer obtained in above formula ( For example the answer may come 13.12 then consider only “13”. Also remember You don’t have to round off the number for example answer may come 36.8 then consider only “36”. Materials Required A4 sheet Color sketches Scale  Ruler

 PARALLEL AND PERPENDICULAR LINES Parallel and perpendicular lines are an important part of geometry and they have distinct characteristics that help to identify them easily. Two lines are termed as parallel if they lie in the same plane, are the same distance apart, and never meet each other. Perpendicular lines are intersecting lines that always meet at an angle of 90°. Let us learn more about parallel and perpendicular lines in this article. Materials Required A4 Sheet. Match Stick. Glue. Color Sketch. Properties of Parallel Lines Parallel lines are always equidistant from each other. They never meet at any common point. They lie in the same plane. Properties of Perpendicular Lines Perpendicular lines always intersect at 90°. All perpendicular lines can be termed as intersecting lines, but all intersecting lines cannot be called perpendicular because they need to intersect at right angles.

SHOW AND TELL   Role play (show and tell) exercises give students the opportunity to assume the role of a person or act out a given situation. These roles can be performed by individual students, in pairs, or in groups which can play out a more complex scenario. Role plays engage students in real-life situations or scenarios that can be “stressful, unfamiliar, complex, or controversial” which requires them to examine personal feelings toward others and their circumstances (Bonwell & Eison, 1991, p.47). Unlike simulations and games which often are planned, structured activities and can last over a long period of time, role play exercises “are usually short, spontaneous presentations” but also can be prearranged research assignments (Bonwell & Eison, 1991, p.47). Benefits of Role Playing Role playing (show and tell) can be effectively used in the classroom to: Motivate and engage students. Enhance current teaching strategies. Provide real-world scenarios to help students learn. L

  TRIANGLE ACTIVITY Colour paper is a favorite for children's crafts because it is inexpensive and is available in many colors. It has a rough texture and is difficult to fold. Construction paper is not for projects that are meant to last a long time because the colors fade quickly. Elementary school teachers often use construction paper for class craft projects. Materials Required Color paper Scale Scissors Glue With this activity, Students learnt how to construct a triangle and are able to recall about triangles based on sides.                                                       

  Japanese Multiplication: Why Diagonal Lines? You might be asking yourself: Why do I always see the lines in the Japanese multiplication method on a diagonal? Well, that’s likely because the majority who are using and sharing the  Japanese multiplication method  may have no idea why it actually works.  By showing the lines diagonally, the base ten block array now organizes the intersection points in order of place value. Have a look below: As you can see above, an opportunity to circle back to place value and the importance of understanding that in base ten, we cannot have any number greater than 9 in any place value column. You’ll notice that the 10 one’s must be swapped out for a ten rod. So while many might consider this to be a pretty cool “trick”, it is much more powerful if students can articulate where procedures like these come from and why they work. This activity helps students to develop the intellectual power of the students . They are very much interested to do this activ

   3D SHAPES A 3D shape has three dimensions. Therefore, unlike a 2D shape, it’s not flat. 3D shapes are measured by length, width and depth. Types of 3D Shapes Cube Cuboid Cone Cylinder Sphere Pyramid Prism Cube A cube is a solid or three-dimensional shape which has 6 square faces. The cube has the following properties. All edges are equal 8 vertices 12 edges 6 faces Cuboid A cuboid is also called a rectangular prism, where the faces of the cuboid are a rectangle in shape. All the angles measure 90 degrees. The cuboid has 8 vertices 12 edges 6 faces Prism A prism is a 3D shape which consists of two equal ends, flat surfaces or faces, and also has identical cross-section across its length. Since the cross-section looks like a triangle, the prism is generally called a triangular prism. The prism does not have any curve. Also, a prism has 6 vertices 9 edges 5 faces – 2 triangles and 3 rectangles Pyramid  A pyramid a solid shape, whose outer faces are triangular and meet to a single point
