TEKS 4.4G: Round and Estimate Solutions
Estimating Solutions
About this lesson
Learning Target: I can use rounding and compatible numbers to estimate sums and differences of whole numbers.
Focuses On:
- Helping students round to estimate solutions to addition and subtraction problems
Builds On:
3.4B:
Round to the nearest 10 or 100 or use compatible numbers to estimate solutions to addition and subtraction problems
Next Level:
5.3A:
Estimate to determine solutions to mathematical and real-world problems involving addition, subtraction, multiplication, or division

This lesson is designed to build vocabulary for estimation and rounding using words such as "about" and "compatible numbers".
The instructional block in this lesson focuses on estimating solutions. After initially rounding, students learn how to use rounded numbers to add and subtract to find estimates to problems. Students will practice solving real-world problems by estimating.
Scaffolds and supports such as pictorial models and visual representations are intentionally built throughout the lesson to support conceptual learning.
