Get children to put their thinking caps on with this Year 3 Subtract 10s Across a 100 Discussion Problem, which features two meaty questions about subtraction. Designed to get kids thinking deeper about their work, this resource includes a space-themed question as well as an investigation into subtraction. We have also included an answer page that provides an example answer for each question, though there may be more than one possible solution.

As this resource is trickier than your average question, we suggest giving your children our varied fluency and reasoning and problem-solving worksheets before this one.
