What is the purpose of the Grade 3 math classroom?
While the content taught in this unit is not major work of Grade 3 as determined by the Common Core State Standards, it serves as a foundation for later work, such as assessing the reasonableness of all types of two-step word problems and multiplying one-digit numbers by multiples of ten. Thus, it serves as an introduction to the course.

We can round down 424 to the nearest hundreds, to estimate the answer.
