Learning how to check our work is essential to becoming strong math students! In this exercise, students will first solve the subtraction problems, then they'll practice checking their work by plugging the answers into an addition equation.
The associative property means you can rearrange the numbers in a multiplication problem and still get the same answer. Students will practice applying this property in various forms and thinking critically about the important math concept.
Let your students show what they know about place value, as they round, determine the value of various digits, and build numbers.
Gain insight into who is ready to take on the challenges in the thousands place and beyond!
