Grade 3 practice sets

Number

Multiplication with arrays and equal groups (to 7 × 7)

The Grade 3 anchor skill. Facts, one array to draw, skip counting, and a check-a-friend reasoning question.

  1. 1.4 × 6 =
  2. 2.7 × 3 =
  3. 3.5 × 5 =
  4. 4.Draw an array for 3 × 8. How many dots in total?

  8. 8.Jonah says 4 × 7 = 27. Use an array or skip counting to check. Is he right? Explain.
Number

Addition and subtraction to 1000

Regrouping practice with an estimate-first question, so the answer key can catch place-value slips, not just wrong digits.

  1. 1.348 + 236 =
  2. 2.517 + 388 =
  3. 3.624 − 258 =
  4. 4.900 − 437 =
  5. 5.Estimate first, then solve: 496 + 312. Is your exact answer close to your estimate?

  8. 8.The fair printed 610 tickets and sold 384. How many tickets are left?
Number

Fractions as parts of a whole

Halves to eighths: naming, comparing with the same numerator or denominator, and one equivalent-amount reasoning question.

  1. 1.A pizza is cut into 4 equal slices. You eat 3. What fraction of the pizza did you eat?
  2. 2.Which is greater: 1/3 or 1/4? How do you know?
  3. 3.Draw a rectangle split into 6 equal parts. Shade 2/6.

  6. 6.Sami and Lena have the same-size granola bar. Sami eats 1/2 of hers. Lena eats 2/4 of hers. Who ate more?
  7. 7.Order from least to greatest: 1/2, 1/8, 1/4.
Spatial sense

Time and perimeter
