Algebra: Write the Expression - Reteach 21.1
It was nice of Jorge to donate some of his personal collection to the book drive, but how do we know what he has left? Prealgebra learners use this example to discover how to write and evaluate a variable expression. They are then given eight phrases to write expressions for. They assign a value of 2 to n and then evaluate each expression. An excellent exercise for emerging expressionists!
