Grade 8 worksheet generator
What eighth graders practice here
Grade 8 sheets put every earlier skill into one expression:
- Decimal numbers as first-class citizens: addends, factors and divisors like
0.5and2.4, not afterthoughts. - Signed decimals together: expressions such as
16 × (-6.5) − ((-8) + 2.5), where a sign error and a place-value error are both one step away. - Exponents over grouped, negative results, like
(6 − 10)^2— the base is computed first, then squared.
Worked example, step by step
Evaluate 2.5 × (6 − 10)^2 ÷ 5 − 3.5:
2.5 × (6 − 10)^2 ÷ 5 − 3.5
= 2.5 × (−4)^2 ÷ 5 − 3.5 (G: group first — 6 − 10 = -4)
= 2.5 × 16 ÷ 5 − 3.5 (E: square the negative base — (-4)^2 = 16)
= 40 ÷ 5 − 3.5 (M/D left to right — 2.5 × 16 = 40)
= 8 − 3.5 (M/D — 40 ÷ 5 = 8)
= 4.5 (S: final answer)
FAQ
What makes grade 8 GEMDAS worksheets harder?
Decimals join negatives. Expressions mix numbers like 2.5 and -6.5 with exponents and nested groups, and some divisions produce decimal quotients. The order of operations is unchanged — the number sense required to follow it is what grows.
Do the decimal divisions on grade 8 sheets come out cleanly?
Yes. The generator only uses divisors such as 2, 4, 5, 8, 10 and 0.5, so every quotient is a finite decimal with one to three places. You will never meet a repeating decimal on these sheets.
Is this practice still useful for algebra?
Very. Substituting values into formulas and evaluating expressions in algebra is exactly GEMDAS with letters turning into numbers. Fluency with signed and decimal arithmetic here is the readiness skill algebra assumes.
