## Unit digit of a cube number

-Logeshwari

8th graders in Udavi School were learning about the squares and cubes. This is a simple scratch project to show the unit digit of cube of a number.

## Fraction multiplication V2

From the STEMland scaling session with Swathi on Friday, the input received was to make the multiplication to be a perfect square to show that 1/4 is smaller than 1/3.

Murali from 9th grade implemented the change:

## Scratch Madala at Aikiyam school

Pratap

This week me and Murali went to Aikiyam to teach shapes using scratch. We started with the drawing a straight line. Then asked children to draw a triangle . Children took some time and then figured out the angle to draw a triangle. Then we asked them to draw the following shapes like square, pentagon, hexagon, heptagon , octagon. Then using this shapes we asked then to draw mandala. Children were interested to draw their own mandalas . Children understood the concept of repeat loop. They were familiar with the pen function in the scratch. Children were able to connect the angles for different shapes.

## scratch program to show equivalent fractions

The following program was created by a 7th grader with the use of functions to show how equivalent fractions work.

## Fraction multiplication with paper folding technique

Paper folding method to learn fractions;

A scratch project was done with the 7th graders to show the same with the pen function.

## Graph with Abinash

Abinash a student from the 8th grade at Udavi school started his work on graph and initially had a little difficulty plotting points. He wanted to create a game for others to understand the concept and so together we started to mind storm on how and what the game should do.

Then he saw a picture on his mathematics text book and decided to create a point follower game at the end of which the user will get an image.

The program was coded in Scratch.

## Number line scratch project.

Pratap

Children in 8th were doing rational numbers and they wanted to build a project to demonstrate their learning . They have build a project in number line. This scratch program shows how to find the fraction in a number line. The numerator is ( a random number is asked from the user. The program chooses a number 0 to 3 x the user number ) and the numerator is also generated randomly (2 – 10). The user needs to find the answer for the question. The user needs to give to a value for numerator and a value for the denominator.

## To find the length of the arc

This scratch program shows how to calculate the length of arc given a valid angle (20 to 360) and radius (50 to 200). The value of angle and radius should be given. It requires two input from the user. If the user doesn’t give a valid input it sets a random value for angle and radius.

## Area of Rhombus = Half the area of a Rectangle given d1, d2

The following program demonstrates that the area of a Rhombus is half the area of a rectangle of given dimensions d1 and d2 and how the pieces can be moved around to form it.
