It’s important to note that this is a general order and can be adjusted based on the needs of the students and the curriculum.

The order of teaching math topics in third grade may vary depending on the curriculum and teaching method used, but in general, a good starting point for teaching math in third grade would be:

2. Place value and number sense up to 10,000
3. Basic operations (addition, subtraction, multiplication, division) with numbers up to 1000
4. Fractions (including adding and subtracting fractions)
5. Measurement and time (including customary and metric units)
6. Geometry and shapes (including perimeter, area, and volume)
7. Basic algebraic concepts (including patterns and functions)
8. Data analysis and probability
9. Basic geometry concepts (angles, points, lines, and planes)
10. Rounding and estimation
11. Telling time to the nearest 5 minutes
12. Money and financial literacy
13. Multi-digit whole number and decimal operations
14. Problem-solving and reasoning
