Free Y1 maths worksheet: solve puzzles and investigate

Free maths worksheet from

The term investigation often seems a little frightening to parents and indeed, some teachers. But a maths investigation can be very simple, as shown by this year 1 maths worksheet.

The question is, “I am three years older than Sammy. How old could we be?”

This is a fairly open ended question, with many possible answers. However, some are not possible eg the elder can not only be 2 years old.

Investigations are all about asking questions; what is the oldest they could possibly be? Why? etc.
