Year 3 – Maths: Multiplication and Division
This week, we have been looking at the relationship between multiplication and division and how we can use this information to help us solve fluency, reasoning and problem solving questions.
Firstly, we have looked at comparing different mathematical statements using greater than, less than and equals symbols.
This is an example of a problem that the children have answered this week.
3×4 > 1×5
In words, this number sentence reads as three multiplied by four is greater than one multiplied by five.
Because 3×4 = 12 and 1×5 = 5, the statement is true.
We then moved on to looking at how we can use what we already know about or 12 times table, and apply it to calculations that may appear challenging.
This is an example of a problem that the children have answered this week.
If 4 x 4 = 16, I know that 40 x 4 is 160 because 40 is 10 times bigger than 4 so the answer will be ten times bigger.
Have a go at these at home:
3 x 3 = ? so 30 x 3 = ?
5 x 4 = ? so 50 x 4 = ? and 40 x 5 = ?
2 x 12 = ? so 20 x 12 = ? and 120 x 2 = ?
