Math Worksheets for 3rd Graders

What 3rd grade children practice

What 3rd grade students should be able to do

• Multiply and divide within 100 and know the facts to 10 by heart.
• Round to the nearest 10 and 100, and estimate sums and differences.
• Add and subtract within 1,000, including across zeros.
• Understand a fraction as a part of a whole and as a point on a number line; find equal fractions and compare fractions.
• Find the perimeter and area of rectangles and other shapes.
• Tell time to the minute and solve elapsed-time problems.
• Measure to the half and quarter inch, read grams, kilograms and liters, and read scaled graphs and line plots.
• Solve two-step word problems with all four operations.

A suggested order for 3rd grade math

1. Skip Counting & Patterns — Counting by 3s to 9s is the foundation of the multiplication tables.
2. Multiplication — Arrays first, then the tables in small groups (2 and 3, 4 and 5, 6 and 7, 8 and 9).
3. Division — Learn division right after multiplication, using fact families to link them.
4. Place Value & Rounding — Rounding and estimating, which also help check answers.
5. Addition — Columns of three and four 3-digit numbers, and making 1,000.
6. Subtraction — Subtracting from 1,000 and across zeros, the trickiest regrouping.
7. Fractions — Start with equal parts and unit fractions, then number lines, equal fractions and comparing.
8. Order of Operations & Properties — Order of operations and multiplication properties, once all four operations are familiar.
9. Geometry: Shapes, Perimeter & Area — Quadrilaterals, then perimeter, then area with square units.
10. Measurement — Half and quarter inches, mass and liquid volume.
11. Telling Time — Time to the minute, then elapsed time.
12. Data & Graphing — Scaled graphs and line plots.
13. Word Problems — Apply everything, including unknown letters and two-step problems.

Tips for using these worksheets

• Practice multiplication facts a few at a time and often. Five minutes daily beats one long session a week.
• Show multiplication as arrays and equal groups before drilling the facts, so the facts mean something.
• For fractions, draw them. A child who can sketch thirds and fourths of a shape understands comparing fractions far more easily.
• When a word problem is hard, have your child underline the question and circle the numbers, then decide which operation to use.
