Reasoning 1
Leo gets £1 per day for helping to cook the dinner.
He says,
Is Leo correct? Explain why or why not.
Leo is correct because he earns £7 each week as there are 7 days
in a week. £7 x 11 = £77, so he will have £2 remaining after buying
his new smartwatch.
In 11 weeks I will have enough money
to buy a new smartwatch.

Reasoning 2
Joanna is thinking about the 7 times table.
She says,
Is she correct? Explain your answer.
Joanna is correct because if 7 x 9 = 63, then the answer needs to be
multiplied by 10 as 90 is 10 times more than 9. Therefore, 7 x 90 = 630
is correct.
If I know that 7 x 9 = 63, then I can
work out that 7 x 90 = 630.
