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

1. Basic operations (addition, subtraction, multiplication, division) with integers, rational numbers, and decimals
2. Ratios, Proportions and percents
3. Basic algebraic concepts (including solving equations and graphing linear equations)
4. Geometry and measurement (including perimeter, area, volume, and angle measures)
5. Data analysis and probability (including mean, median, mode, range, and probability)
6. Basic geometry concepts (points, lines, planes, and symmetry)
7. Rounding and estimation
8. Basic concepts of geometry in 2D and 3D, including symmetry and transformations.
9. Basic concepts of statistics and data analysis.
10. Basic concepts of exponents and scientific notation
11. Basic concepts of square roots and basic concepts of geometry(surface area and volume)
12. Basic concepts of ratios, rates, and unit rates
13. Basic concepts of proportional reasoning
14. Basic concepts of absolute value and integers
15. Basic concepts of prime factorization
16. Problem-solving and reasoning
17. Graphing and data interpretation
18. Mental Maths
19. Basic concepts of equations and inequalities
20. Basic concepts of geometry and measurement conversions
