7th? Right in my wheelhouse, I see 100 of them every other day.
1. Ratios and Proportions: Fractions and being able to convert decimals to % to fractions and mix n match.
-Compound Fractions, love them and embrace them, big component of this section.
-Equivalent ratios
-Tables, graphs, equations
-Tax, Markups/Markdowns, Commissions, Fees, % increase
2. The Number System:Horizontal and Vertical Number lines, Mult/Div Fractions
3. Expressions and Equations: Add/Subtract linear equations, heavy word problems in this section involving fractions and decimals
4. Geometry: Angles, Circles, Volume, Scale Drawings, Triangles, Rectangular prisms, interesting section IMO.
5. Stats and Probability: Pretty straight forward.
The codes are 7.RP, 7.NS, 7.EE, 7.G, and 7.SP if you are looking for specifics at say teachers pay teachers which is actually loaded with freebies if you look around.
Good luck!
