With the help of the example shown complete the equations given below. Count the total number of glasses and write the value in the green colour circle. Now count the empty glasses and write its value in the pink colour circle. Following the decomposition concept, reduce the second number from the first number and write the decomposed number value in the white colour circle. With the help of your teacher read the equation with symbol names, subtract and equals to.
On the sheet
The sheet displays glass subtraction exercises using water-filled and empty glasses. The first row is an example with 2 full glasses and 1 empty glass, showing 2 - 1 = 1. Children count the glasses in the other three rows and write the corresponding equations.
