Learning time

Kids learn by watching short, engaging video lessons.

Another type of multiplication problem you can solve is called missing factor problems. So, this is where instead of trying to find the answer to the multiplication equation, one of the factors in the equation is missing. So, to look at this, we're going to use the equation blank times 5 equals 15. So, instead of trying to find the answer, we're going to try to see what this missing factor is. So, we know that the second number that you're multiplying by is 5. This means that there are groups of 5. We don't know how many groups there are so we're going to skip count by 5 to see how many groups there are until we get to 15. So, we're going to skip count by 5’s, 5, 10, 15. We got to 15 which is the answer to the equation, and we skip counted three times. This means there are 3 groups of 5. That means the missing factor in this equation is 3, so 3 x 5 = 15.

Kids earn more screen time by answering fun educational questions.

Recreational screen time

Kids can use the screen time minutes they earned to unlock the apps selected by their parent e.g. games, social media, streaming, etc.

Out of time

When screen time minutes run out, kids are locked out and need to complete more learning in 1Question to earn more time.
