Class VII- The Decimal Diamond (Activity)

The students of class VII revised the basic operations of decimals to complete the given arithmagon of decimal numbers. 

They selected a starting value of variable 'a' and a decimal number 't' (between 0 and 1) and then used the given equations to calculate the value of remaining variables and unknown numbers to fill all the circles of arithmagon. 

They used the concept of average or mean to find the value of rectangles given in the mid of the line joining two circles.
