Maths

Do you struggle with balancing your kids’ screen time with their education? Say hello to 1Question, the app that solves this problem with a fun twist! Our app lets your child earn screen time minutes in their favourite apps by watching educational videos and correctly answering quiz questions. And the best part? You get to decide which apps to lock behind learning using 1Question.

Learning time

Kids learn by watching short, engaging video lessons.

Sometimes numbers follow a pattern and we need to figure out what the rule is so we can figure out the next number in the pattern. Let's figure out what's happening in this number pattern – 1,4,7,10, __. It looks like we're adding three each time. 1 + 3 is 4, 4 + 3 is 7, 7 + 3 is 10, 10 + 3 is 13. Thirteen is our missing number according to the rule - add three. What do you notice about these numbers – 11, 9, 7, 5, 3? Are they increasing or are they decreasing? It looks like we’re subtracting by 2 each time. But we need to make sure we tell where we start from and included it in our rule. So, our rule would be – start at 11 and subtract 2. So, when you are working with number patterns it’s good to use the knowledge you already have, whether the numbers are going up or down, whether they’re adding, subtracting, multiplying or dividing.
