Break apart and turn around to multiply

With these shortcuts in hand, your child no longer faces 100 separate facts to memorize one by one. Breaking 4 x 7 into 4 x 5 and 4 x 2 turns one hard fact into two easy ones. The same move returns in 4th grade, where 6 x 23 becomes 6 x 20 plus 6 x 3, and again in middle school algebra, so it is one of the most useful ideas your child will meet.

In this video, your child will learn to break apart and turn around times problems.

The lesson stops at each question for your child's answer.

Three problems, each a little harder

Each problem is worked step by step. Your child will solve the last one before Bobby shows how.

Example 1

4 × 7 = ?

Example 2

7 × 5 = 5 × ?

Your child's turn

6 × 8 = ?

The three key steps

  1. 1Break it into facts you know.
  2. 2Multiply each part, then add.
  3. 3Turn it around: same answer.

Mistakes to listen for

  • Breaking a number apart but multiplying only one piece, so 4 x 7 becomes 4 x 5 + 2 = 22 instead of 28.
  • Expecting the order trick to work for division too, so 12 ÷ 3 and 3 ÷ 12 seem equal.
  • Splitting a number into awkward pieces, such as 7 into 3 and 4, which leaves facts no easier than before.

Questions parents ask

Does my child need an account to watch?

No. You can watch this on any device at any time. If your child would like to practice shortcuts that make times tables easier, and you'd like parent-friendly reports on your child's progress and growth, you can join Bobby's Math Club for unlimited free practice.

What happens when my child answers a question?

A right answer gets a cheer, and the lesson carries on. If your child isn't sure, they can tap "I don't know yet", and Bobby gives the answer and shows another example. Nothing is scored or stored.

Is this the same lesson that's on YouTube?

Yes. Here, the lesson stops at each question and waits for your child to answer. On YouTube, each question stays on screen for a few seconds, and then the lesson plays on.

Where can I learn more?
