Order of operations plus writing simple expressions (4th grade math)

We go through several calculations that involve parentheses, multiplication, division, addition, and subtraction, using the correct order of operations.

Then, the lesson focuses on WRITING simple expressions from word descriptions or for real-life situations. This skill prepares children for algebra -- because putting several operations together into a single "number sentence" or expression involves algebraic thinking.
