Go Math! Grade 3, Chapter 4: Multiplication Facts and Strategies
In this unit, your child learns the 2s, 4s, 5s, 10s, 3s, and 6s using strategies such as doubling and breaking facts apart. They spot patterns in the multiplication table and explain why they work, then solve story problems, including two-step ones. Next, these facts get used to find missing numbers and to multiply by multiples of 10.

What is my child learning in Chapter 4?
- Solving story problems with the 3s and 6s, such as 6 packs of 3 balls, by drawing a model and writing an equation. Learn more: Multiplying and dividing in story problems
- Learning facts for 2, 3, 4, 5, 6, and 10 by heart using doubles, so 4 × 7 is double 2 × 7. Learn more about knowing the times tables by heart: Knowing the times tables by heart · Learn more about dividing within 100
- Solving two-step problems that mix multiplication with addition or subtraction, such as 3 boxes of 6 crayons plus 4 more. Learn more: Story problems with two steps
- Explaining patterns like why 4 times any number comes out even, using the multiplication table. Learn more: Spotting patterns in times tables
Sample questions to try together
These are real questions from our practice. Tap the speaker to hear one read aloud, or the light bulb for a hint, and talk about the answer together.
Question 1 of 3
Ravi finds 16 socks in the laundry. He puts them into pairs, with 2 socks in each pair. How many pairs does he make?
- 8
- 32
- 14
How you can help
- Ask your child to double a 2s fact out loud to find a 4s fact, such as 2 × 8 = 16 so 4 × 8 = 32, while waiting in line.
- Count house numbers on a walk and notice that one side of the street is often all even, then ask why adding 2 keeps it that way.
- Make up a two-step problem at the store, such as 3 packs of 6 yogurts with 4 more already at home, and ask how many in all (22).
Where kids can get stuck
- Doubling the wrong fact, so 4 × 6 is found by doubling 2 × 4 and comes out as 16.
- Counting on fingers for every fact, which works for 2s and 5s but slows down on the 6s.
- Losing their place in the multiplication table or reading a row as a column.
