Elementary Algebra is generalized form of arithmetic. It provides a language to represent problems and functions. Algebraic thinking is also one of the first forms of abstract thinking that students develop in mathematics. It is most critical to understand what mental model your child has established and then look to mould and correct that model giving different examples. Lets look at some of the common gotchas of algebraic learning.
Real-World Algebra Activity. Use A variety on Items around the classroom. Set a variable and a price to represent each item. (You can even allow the students to determine the prices). Have the students shop for items or create a shopping list for them. Students will need to write expressions that match their list, Then solve each expression to determine the final cost. Students practice writing algebraic expressions and multiplying and adding decimals. (Examples are provided on webpage)
