The product is the other number.

1 * 2 = 2
1 * 5 = 5
1 * 10 = 10
lol wtf? 4th grade?
This is
Identity property of multiplication

states that the product of 1 and any number or variable is the number or variable itself. For example, 4 × 1 = 4, - 11 × 1 = - 11,

The teacher is probably trying to help them learn this particular property.

You are a great parent by the way!!!
the product of any number and one is the number being multiplied by one for example 1*1=1
2*1=2
3*1=3
4*1=4
5*1=5
