From our teachers' playbook

The year of multiplication

What do 3rd graders learn in math?

Third grade is the big multiplication year. Kids learn that 4 × 6 means four groups of six, connect it to division, and work toward knowing their facts within 100 by heart. They meet fractions as real numbers on a number line, find area by counting squares and then by multiplying, and measure perimeter around the outside. They also round to the nearest ten and hundred and add and subtract three-digit numbers with regrouping. The click is when a child sees that the area of a 3 by 5 rectangle is just 3 × 5 = 15.

Our favorite ways to teach 3rd grade math

Third grade math moves fast. These moves build real understanding and quick recall at the same time.

How did you see it?

Show a rectangle on a grid and ask, "How many squares? How do you know?" One child counts, one skip counts by rows, one multiplies. Comparing strategies out loud is how kids discover that multiplying is the fastest route.

Why it works: using clear, consistent math words out loud is one of the U.S. Department of Education's recommendations for elementary math.

Skip count to the facts

Skip-counting songs are a ladder to multiplication facts. Sing the fours together, then ask, "What's the 6th number?" That's 4 × 6! Kids pull up facts by humming the tune.

Why it works: words set to a repeating melody are easier to recall than the same words spoken (Wallace, 1994).

3rd grade math: your questions

What math should a 3rd grader know by the end of the year?

Most 3rd graders know multiplication and division facts within 100, understand fractions as numbers on a number line, find area and perimeter, round to the nearest ten and hundred, and add and subtract within 1,000.

How can I help my child learn multiplication facts?

Start with the easy ones: 2s, 5s and 10s. Skip-count songs and short daily practice of five minutes work better than long drills. Point out that every fact gives you a free partner: if 3 × 7 is 21, so is 7 × 3.

What's the difference between area and perimeter?

Area is the space inside a shape, measured in square units. Perimeter is the distance around the outside. A quick trick: area covers, perimeter walks around.

How are fractions taught in 3rd grade?

Kids learn that a fraction like 3/4 means three equal parts out of four. They place fractions on a number line, compare fractions with the same top or bottom number, and find simple equivalent fractions like 1/2 = 2/4.

Do 3rd graders take state tests in math?

In most states, yes. Third grade is often the first year of state testing. Short practice with mixed question types helps kids feel calm and ready.
