Helping at home
In 3rd grade, children learn to multiply a one-digit number by 10, 20, 30 and so on up to 90, using place value. 6 × 40 is 6 groups of 4 tens, which is 24 tens, or 240.
The common slip is following a rule without understanding it, such as "add a zero," and then adding the zero in the wrong place or forgetting it. Some children also multiply 6 × 4 and stop at 24.
One way to help at home: say it with tens. "6 times 4 tens is 24 tens. What is 24 tens?" Money helps too: 6 groups of 40 cents is 6 groups of 4 dimes, which is 24 dimes, or $2.40. This skill is the base for multiplying bigger numbers in 4th grade, so it is worth getting secure.
