A comprehensive math course designed for third grade students to build foundational skills in numbers, operations, geometry, and data analysis.
After solving a math problem, it's important to check your answer. You can do this by doing the problem in a different way, using the opposite operation (like checking subtraction with addition), or by estimating to see if your answer makes sense.
Checking your work helps catch silly mistakes and builds confidence!
After adding 145 + 256, subtract 145 from your answer to see if you get 256.
If you finish a word problem, read it again and make sure your answer matches what the question is asking.
