lesson plan(making triangle): using cuisenaire rods

My lesson plan is to make triangle by using cuisenaire rods that is taken from the CD.In this lesson the students will find out to make different triangle by using differents rods. Students need to specify how to connect the edges of the rods. the special technique is that the two rods can be pushed down or lie down but can not be overlapped. Students need to find out any three rods is aable to construct a trangle? what is the reason for possible answre? student need to make a list of the combinations of rods that make triangle and other combination that don't make triangle. students need to explore of the properties of triangle like the lengths of two sides of a triangle are greater than the third side. students will ask to findout equuilateral triangle(all sides are equal), isosceles triangle(two sides are equal), scalene triangle(no sides are equal). finally student will ask to find any pattern is present in this process there.

NLVM-Geoboard for 6-8 grade to illustrate area, perimeter

I found this manipulative practice is a fun way of learning to illustrate different kind of polygon and measuring their area and perimeter. student can findout one polygon in different size and can measure its area and perimeter and also able to findout the possible maximum area and perimeter. student also can able to findout the relationship between the area of triangle and rectangle. student shouldn't limit their talents they can able to illustrate different kind of open and closed polygon. This lesson will help student to explore their geometric knowledge of polygon by themselves very fun way.

Area of Rectangle and Square.

NJCCCS: 4.2E1
OBJECTIVE:
SWBAT understanding the area of rectangle and square.

Pre- Discussion and Activity:
# Discuss about rectangle and squae and the area.
# Explain how to use geoboard and rubberband to make rectangle/square
# Explain how to draw model of rectangle and square on geo dot paper
# Mention the student about the distance between two pegs is one square unit.
# Measuring Area: Space to be measured in the center of a geoboard for an object two ways:
WAY-1: we can draw a model of rectangle or a square on geodot paper and count on squares.
Way-2: we can use the formulla of area= length*weidth

Materials:Geo Boards, Rubber bands, Geo dot Papers. Pencils.

Assesments:
- what is the area of square and rectangle and there is any differenc

Homework-
- Draw different sizes Rectangles and Square and find areas by using geo boards

Lesson Plan/Geometry(Polygons and its different shapes)

Mohammed Uddin
Grade-5
Mathematics

Objective:
SWBAT understanding the polygon and its different shapes, name it, learning angles and parallel lines.

Activity and Discussions:
# Before go to details operative activities explain students about polygon, its shape(closed/open), the lists of polygon(like different kind of triangle, rectangle, pentagon, hexagon etc.)
#Explain different angles, parallel lines.

# Expalin how to use Geoboard with rubberbands .

#Let Student create different Triangles-
Right angle, acute angle, obtuse angle

Different types of Quadilaterals-
Rectangle, Square, rumbas, Trapezoid

Other Polygons-
Pentagon, Hexagon so on.

Materials:
Geo Boards, Rubber Bands, Geodot Papers, Pencils

Assesments:
- Ask Questions about different angles, shape, and parallel line.
- In Which description the shapes are congurent?
- In Which shape two pairs parallel lines but not right angle?
- In Which shape has two pairs parallel line and right angle?
- In Which shape has only one pair parallel lines?
Homework:
- Draw different shape of polygons with their name on.
