Introduction to constants, variable and unknown through patterns and through appropriate word problems and generalisations (For example 1+3=22, 1+3+5=32, 1+3+5+7=42 , sum of first n odd numbers = n2.)

Generate such patterns with more examples and generalisation

Introduction to unknowns through examples with simple contexts (single operations)
