How do you make a maths working model for class 7?

Answer 1

Math Model for Class 7

Here are some suitable models for students of 7th Standard which they can easily create.

Sum of N Even Numbers: Draw a table in a big sheet of paper, having at least ten rows and columns (you can exceed them). Write and show even numbers in different colours. Now you can show the sum of first n even numbers using the formula n(n+1). You can also use this model to represent the sum of N odd numbers.

Types of Angles: Students can show different types of angles such as acute angle, right angle, obtuse angle, using colourful pencils or sketch in a big sheet of paper.

Lines and Transversal: Use thermocol and cut two parallel lines and one transversal in it. Now show all the eight angles formed by a transversal on the intersection with the two lines.

Answer 2

you should try a Pythagoras theorem in which you can show the volume of cone is 1/3 of the volume of a cylinder (both having same h and r) or you can try to make simple models of cube,cuboid,sphere,cone,cylinder,square and triangular pyramids and then can explain that how to find the area,perimeter,volume,faces,sides etc.

other than these you can also try to make a geoboard.

all the best!
