Do you want to put your children's place value and number line knowledge to the test? Let them try our Year 4 Number Line to 1,000 Discussion Problem. This resource includes an open-ended problem-solving question that is designed to get children thinking, applying what they know and putting their reasoning and problem-solving skills into practice.

It can be used as a paired or small group activity to encourage mathematical discussion within your class. Alternatively, you could use this to extend children's understanding by using this in an intervention group, or open up the discussion to the whole class and display the question on your screen. An example answer is provided for children to compare their outcomes to, or display this to demonstrate the multiple possible answers to this question.
