Grade 7 math practice
Grade 7 treats an equation as a balance, shares an amount in a ratio, and multiplies three edges to find the volume of a box. Percent of a number continues from grades 5 and 6 into percent increase.
The percent, linear equations, ratio, and volume lessons are shared with grade 8 and linked from here. Each lesson has one URL. Solving 2x + 3 = 11 is the practice skill on the equations page.
Topics
Linear equations — Keep both sides of an equation equal while you undo one operation and solve for the unknown.
Percentages — Find a percent of a number, then describe a price change as a percent increase.
Ratios — Share an amount in a given ratio by splitting it into equal parts first.
Volume of a box — Multiply length, width, and height to find how much space a box holds.
Exponents — Read a power as repeated multiplication, then expand a product such as (x+2)(x+3).
Sample exercises
