What Is Estimation? 

Are your students struggling with the concept of estimation? While this is a tricky concept for young learners to grasp, it is an important one that will be used in their daily lives! While students may have heard this term in relation to guessing how many jelly beans are in a jar, students begin to use estimation with the 4 operations. Let’s take a look at a quick way to explain estimation to your students.

Estimation is a thoughtful guess about the value of something. In order to make a thoughtful guess, different strategies are used with whole numbers, such as rounding and using compatible numbers.

Estimation is a helpful skill in many parts of life, like when you’re shopping and need to estimate the cost of items or when you’re doing math and want a quick idea of what the answer might be without doing a long calculation. 

Looking For 3rd Grade Estimation Worksheets? Try a Maze Instead!

If you are looking for extra practice pages for your students to complete when teaching about estimating sums and differences, you have come to the right place! Teach Starter has created a set of 3 math mazes for students to refine their rounding skills and add or subtract numbers.

• Maze 1: Rounding to the nearest 10 with two-digit numbers
• Maze 2: Rounding to the nearest 10 with three-digit numbers
• Maze 3: Rounding to the nearest 100 with three-digit numbers.

To complete the mazes, students will begin in the “Start Here” box. They will round each of the numbers and determine the sum or difference. Guide students to find the correct answer and color in the correct box. Students will work their way through different problems until they stop at the “End Here” box.

Each maze also comes with an included answer key for quick and easy grading!
